Eduard Suess in 1875? Hydrosphere Thermosphere Atmosphere
Lithosphere Biosphere
The term which is not one of the four spheres defined by Eduard Suess in 1875 is Thermosphere.
Eduard Suess:
Eduard Suess was an Austrian geologist who is renowned for his contributions to geology and biology, especially in the theory of continental drift and the idea of the supercontinent Gondwana. Suess was one of the first people to describe the four spheres of Earth. These are the atmosphere, the lithosphere, the hydrosphere, and the biosphere. All of these spheres of the earth play an important role in the survival of living organisms on Earth and in maintaining balance. The thermosphere is not one of the four spheres of the Earth that Eduard Suess defined in 1875. The thermosphere is the layer of Earth's atmosphere that lies above the mesosphere and below the exosphere. It is the highest region of the atmosphere. The thermosphere is not a distinct sphere, unlike the four other spheres identified by Eduard Suess.The thermosphere is extremely hot, and the temperature may reach up to 1,500°C. Because of its high temperature, the thermosphere is home to phenomena such as the auroras and meteors.

is the part of the Moon we cannot see, which occurs the Sun is at the center of the Solar System.
The dark side of the Moon refers to the part of the Moon that is not visible from Earth due to its tidal locking, where one side always faces us. It does receive sunlight; however, it is often referred to as the "dark side" because it is unseen from our perspective.
The correct option is (a).
The dark side of the Moon is the part of the Moon we cannot see from Earth. This occurs because the Moon is tidally locked with Earth, meaning it takes the same amount of time to rotate on its axis as it does to orbit around Earth. As a result, one side of the Moon always faces Earth, while the other side remains hidden or "dark" to us. It is important to note that the term "dark side" does not imply that this side of the Moon is always in darkness, as all regions of the Moon receive light from the Sun except for some deep crevices.

Nicolaus Copernicus proposed that if the Earth orbited the Sun, the varying positions of Venus relative to the Sun and Earth would cause it to exhibit different phases like the Moon. However, in the geocentric model, Venus was always seen as a full or crescent shape. This inconsistency strongly supported the heliocentric model, which placed the Sun at the center and explained the observed phases of Venus as a result of its orbit around the Sun.

Would the introduction of (hypothetical) anthropogenic
pollutants into the river at an upstream site affect the chemical
composition of the coastal water?
Yes, the introduction of hypothetical anthropogenic pollutants into a river at an upstream site can indeed affect the chemical composition of the coastal water.
Rivers serve as natural pathways that transport water and various substances from inland areas to the coast. When pollutants are introduced into the river, they can be carried downstream and eventually reach the coastal water.
The pollutants can alter the chemical composition of the coastal water in several ways. They can introduce new chemical compounds or elements that were not originally present in the coastal water, thereby changing its overall composition. For example, if toxic chemicals or heavy metals are released into the river, they can contaminate the coastal water and potentially harm marine organisms.
Additionally, the pollutants can also affect the balance of nutrients and other essential elements in the coastal water. Some pollutants may act as fertilizers, leading to an excessive growth of algae and causing an imbalance in the ecosystem. This process, known as eutrophication, can result in oxygen depletion and the formation of "dead zones" where marine life cannot survive.
Moreover, certain pollutants can have long-term effects on the coastal water and its ecosystems. They can accumulate in the sediment or be taken up by organisms, leading to bioaccumulation and biomagnification in the food chain.
It is important to note that the specific impact of anthropogenic pollutants on the coastal water will depend on the nature and quantity of the pollutants, as well as the characteristics of the river system and coastal environment.

The state of Georgia has come up with several strategies to balance forest conservation and economic development. The three strategies and the ways they can achieve the goals of both conservation and development are as follows ;
A clear-cutting method is adopted for timber harvesting. In a clear-cutting method, all trees in a given area are felled at the same time, and the soil is left to regenerate for a specific period. This strategy ensures that there is a balance between forest conservation and economic development. Trees that are harvested are replanted, and the land is left to regenerate and maintain its ecosystem. This ensures that forests remain as they are and remain a source of income.A strategy of controlling pollution in the area of forest preserves can help to conserve the forest and promote economic development. Preventing or managing pollution and minimizing environmental harm caused by development activities can help to protect and maintain forest land as well as promote sustainable economic growth. By protecting forests from pollution, you can create a healthy environment for the forest and promote biodiversity in the area. This, in turn, leads to economic development. Because forests can generate economic benefits from tourism and recreation, this leads to economic growth.The implementation of responsible forestry practices is another strategy that can help balance forest conservation and economic development. Georgia has adopted a certification scheme called the Forest Stewardship Council (FSC), which ensures that forestry operations adhere to sustainable forest management standards. This certification scheme ensures that forests are preserved and economically exploited in a responsible manner. This scheme also helps to ensure that the forest ecosystem is maintained, and the forest can generate economic benefits through sustainable forestry practices.Thus, the three strategies the State of Georgia has come up with are clear cutting method, controlling pollution in forest area and Forest Stewardship Council certification scheme.

A wind farm consisting of 10-m diameter wind turbines with efficiencies of 40% will be built. Evaluate the average output power in kW per km² if the wind blows at the average velocity of 6 m/s by considering that the air density, p is equal to 0.602 kg/m³. It is important to be noted that the average spacing of the wind turbines downwind will be 10 times the rotor diameter and the crosswind spacing will be 3 times the rotor diameter.
To evaluate the average output power of the wind farm, we need to consider the power captured by each wind turbine and the number of turbines per unit area.
The power captured by each wind turbine can be calculated using the formula:
Power = 0.5 * density * area * velocity^3 * efficiency
where density is the air density, the area is the swept area of the turbine, velocity is the wind velocity, and efficiency is the turbine efficiency.
The swept area of the turbine can be calculated as:
Area = pi * (diameter/2)^2
Considering the given values, we can calculate the average output power per unit area as follows:
Swept Area = pi * (10/2)^2 = 78.54 m²
Power = 0.5 * 0.602 kg/m³ * 78.54 m² * (6 m/s)^3 * 0.4 = 679.73 kW
The spacing of the wind turbines downwind is 10 times the rotor diameter, which is 10 * 10 m = 100 m. The crosswind spacing is 3 times the rotor diameter, which is 3 * 10 m = 30 m.
Therefore, the average output power per km² can be calculated by dividing the total power by the area covered by the wind farm:
Power per km² = Power / (1000 m * 1000 m / (100 m * 30 m)) = 67.97 kW/km²
Hence, the average output power of the wind farm is 67.97 kW per km².

A social scientist believes that the marital status of Malaysian men is dependent on their religious affiliation. A sample of 500 Malaysian men is surveyed, and the results are tabulated as shown below: Marital Status Religion A Religion B Religion C Non-Religion Divorced 46 26 19 25 Married 100 50 31 29 Single 90 29 30 25 Calculate the expected frequencies.
The null and alternative hypotheses can be formulated based on the data. The null hypothesis states that the marital status of Malaysian men is not related to their religious affiliation. In contrast, the alternative theory states that the marriage status of Malaysian men is related to their religious affiliation.
We will use the chi-square goodness-of-fit test to investigate whether the observed data significantly differs from the expected data. We will use a significance level of α = 0.05 for the test. The expected frequency for each category is the product of the marginal totals for that category divided by the total number of observations. Here are the calculations: Total number of observations = 500Divorced: Religion A: 500 × (46 + 26 + 19 + 25)/500 = 45.36 Religion B: 500 × (46 + 26 + 19 + 25)/500 = 45.36 Religion C: 500 × (46 + 26 + 19 + 25)/500 = 45.36 Non-Religion: 500 × (46 + 26 + 19 + 25)/500 = 45.36 Married: Religion A: 500 × (100 + 50 + 31 + 29)/500 = 101 Religion B: 500 × (100 + 50 + 31 + 29)/500 = 101 Religion C: 500 × (100 + 50 + 31 + 29)/500 = 101 Non-Religion: 500 × (100 + 50 + 31 + 29)/500 = 101Single: Religion A: 500 × (90 + 29 + 30 + 25)/500 = 79.64 Religion B: 500 × (90 + 29 + 30 + 25)/500 = 79.64 Religion C: 500 × (90 + 29 + 30 + 25)/500 = 79.64 Non-Religion: 500 × (90 + 29 + 30 + 25)/500 = 79.64.

Case Study 1: Calculating Ecological Footprints In 2004, coffee consumption in the United States topped 2.7 billion pounds (out of 14.8 billion pounds produced globally). Next to petroleum, coffee is the most valuable commodity on the world market, and the United States is its leading importer. Most coffee is produced in large tropical plantations, where coffee is the only tree species and is grown in full sun. However, approximately 2% of coffee is produced in small groves where coffee trees and other species are intermingled. These shade-grown coffee forests maintain greater habitat diversity for tropical rainforest wildlife. Given the information above, estimate the coffee consumption rates in the table below. Assess the following and fill in the table. Data from O'Brien, T. G., and M. F. Kinnaird. 2003. Caffeine and conservation. Science 300:587; and International Coffee Organization. Questions: 1. What percentage of global coffee production is consumed in the United States? If only shade-grown coffee were consumed in the United States, how much would shade-grown production need to increase to meet that demand? 2. How much extra would you be willing to pay for a pound of shade-grown coffee, if you knew that your money would help to prevent habitat loss or extinction for animals such as Sumatran tigers, rhinoceroses, and the many songbirds that migrate between Latin America and North America each year? Explain your answer. 3. If everyone in the United States were willing to pay as much extra per pound for shadegrown coffee as you are, how much additional money would that provide for conservation of biodiversity in the tropics each year?
1. What percentage of global coffee production is consumed in the United States? If only shade-grown coffee were consumed in the United States, how much would shade-grown production need to increase to meet that demand?Answer:
Out of the 14.8 billion pounds of coffee produced globally, coffee consumption in the United States tops 2.7 billion pounds. So, the percentage of global coffee production consumed in the United States is 18.24% (2.7/14.8*100 = 18.24%).If only shade-grown coffee were consumed in the United States, it would increase the shade-grown coffee production by 18.24% to meet the demand. Therefore, the required increase in the production of shade-grown coffee would be 0.36 billion pounds (2.7*0.02/0.98 = 0.36).
2. How much extra would you be willing to pay for a pound of shade-grown coffee, if you knew that your money would help prevent habitat loss or extinction for animals such as Sumatran tigers, rhinoceroses, and the many songbirds that migrate between Latin America and North America each year? Explain your answer.Answer:
The willingness of an individual to pay more for a pound of shade-grown coffee will differ.Here is an example:
If someone is willing to pay $0.25 extra for shade-grown coffee, which is an average price range, they would be spending an additional $ 675 million per year (0.25*2.7*10^9 = 675,000,000)for shade-grown coffee. This could help prevent habitat loss and extinction for animals such as Sumatran tigers, rhinoceroses, and the many songbirds that migrate between Latin America and North America each year.
3. If everyone in the United States were willing to pay as much extra per pound for shade-grown coffee as you are, how much additional money would that provide for the conservation of biodiversity in the tropics each year?Answer: If everyone in the United States were willing to pay $0.25 extra per pound for shade-grown coffee, this would generate an additional $6.75 billion per year for the conservation of biodiversity in the tropics (0.25*2.7*10^9*100/18.24 = 6,746,875,000).

Explain in your own words subglacial sediment
deformation, outlining under what conditions it occurs and the
endogenic and exogenic processes that may be associated with
it
Subglacial sediment deformation occurs when the weight and movement of ice cause the sediment beneath a glacier or ice sheet to compact and rearrange, resulting in the formation of landforms and processes such as subglacial till and erosion by meltwater.
Subglacial sediment deformation refers to the mechanical processes that occur within the sediment beneath a glacier or ice sheet. It happens when the weight and movement of the overlying ice cause the sediment to deform and rearrange. This process occurs under specific conditions where the ice exerts pressure on the sediment, causing it to compact and deform. Endogenic processes associated with subglacial sediment deformation include the formation of subglacial till, which is a mixture of sediment and water and the development of subglacial landforms such as drumlins and eskers. Exogenic processes can include erosion, transportation, and deposition of sediment by meltwater flowing at the base of the glacier. Overall, subglacial sediment deformation is a dynamic process that plays a significant role in shaping the landforms and geological history of areas covered by glaciers and ice sheets.

An eruption that produced fountaining lava usually produces a Shield volcano.
What is a Shield volcano?
A shield volcano is a wide volcano that has gently sloping sides and is formed by the slow flow of basaltic lava from a central crater. Shield volcanoes are named after their shape, which resembles a Roman shield lying on the ground.
What are the characteristics of a Shield volcano?
Shield volcanoes have the following characteristics: They are composed of a wide, flat cone with gently sloping sides that are formed by the slow flow of basaltic lava from a central crater. They are frequently found in oceanic settings and are mostly composed of basaltic lava. They are very large and may cover several hundred square kilometers. For instance, Mauna Loa, which is the largest volcano on Earth, covers an area of around 2,035 square miles (5,271 square kilometers).They are not usually explosive. However, they can create fissure eruptions that can cause significant destruction and damage to the environment. They have a more gradual, passive flow of lava that typically does not travel far from the volcano.
How do Shield volcanoes erupt?
When a shield volcano erupts, it spews out lava, which flows down the sides of the volcano in rivers or streams. The lava is typically very fluid and has a low viscosity. As a result, it can flow long distances and may travel several kilometers away from the volcano.Shield volcanoes can also have explosive eruptions, particularly if water or other volatile substances come into contact with the lava. These explosions can create pyroclastic flows, which are hot, fast-moving clouds of ash and gas that can be very dangerous to people and animals in the vicinity of the volcano.

[10 marks] b) Give ONE (1) example of seismic processing method using data of geological model and ideal seismic response to process seismic acquisition data. [4 marks] c) Illustrate ONE (1) example of hot spot formation using appropriate sketch. [6 marks] d) Give TWO (2) examples of basin development from crustal deformation.
a) The five (5) differences between seismic reflection and seismic refraction are given below:
i. Seismic reflection: It measures the time taken for sound waves to reflect off subsurface boundaries and return to the surface. Seismic refraction, on the other hand, measures the time it takes for sound waves to pass through different layers of rock or sediment. ii. Seismic reflection provides information about subsurface layers' geometry and structural features, whereas seismic refraction provides information about the depth and velocity of subsurface layers. iii. Seismic reflection can be used to locate oil and gas reserves, while seismic refraction is used to detect geologic formations such as faults and folds. iv. Seismic reflection uses high-energy sources such as dynamite or air guns, while seismic refraction uses small energy sources like hammer blows or weight drops. v. Seismic reflection is more accurate in shallow waters, while seismic refraction is more accurate in deep waters.
b) One example of a seismic processing method that uses data of geological model and ideal seismic response to process seismic acquisition data is seismic inversion. Seismic inversion is the method of constructing a geological model from seismic data. It is used to estimate rock and fluid properties from seismic data. It converts seismic data into quantitative rock property estimates, such as porosity, lithology, and fluid content.
c) The example of hot spot formation can be illustrated using the following sketch: Image: https://imgur.com/x2tUwTJ The sketch shows a mantle plume rising from the Earth's core-mantle boundary, heating up the overlying rock and forming a hot spot. As the tectonic plates move over the hot spot, they create a trail of volcanic islands and seamounts. An example of a hot spot is the Hawaiian-Emperor seamount chain in the Pacific Ocean.
d) The two (2) examples of basin development from crustal deformation are given below: i. Rift Basin: It is formed by the extensional forces that pull apart the Earth's crust, creating a series of faults and fissures. These basins are often associated with volcanic activity and are found along the edges of tectonic plates, such as the East African Rift. ii. Foreland Basin: It is formed by the compression of the Earth's crust due to the collision of tectonic plates. The basin is located in front of the mountain range, and it is filled with sediments eroded from the mountains. An example of a foreland basin is the Persian Gulf Basin.
