what is Lithosphere?
Answers
On Earth, the Lithosphere is best described as the outer part of the Earth which includes the crust and upper mantle.
Where does the Lithosphere exist?The Lithosphere is the part of the Earth that we are on. It consists of the crust and the upper mantle.
It is above the mantle and is made up of pieces called tectonic plates that are constantly in motion.
It is these tectonic plates that the continental crust rests on. This is why continents are said to be shifting. Oceanic crusts are also part of the lithosphere and are more denser.
The Lithosphere is approximately 62 miles thick which is quite thick but not as thick as the mantle which is about 1,802 miles thick. The core is even thicker as it is separated into two parts - inner core and outer core.

Answer the 1. Discuss briefly the causes, and consequences of climate change and how can we respond to the changing climate in the context of Ethiopia? (2%) Discuss in detail about the population characteristics of the Ethiopia. Your discussion needs 2
Answers
The causes of the climate change of Ethiopia are rapid deforestation, rapid population growth and agricultural expansions, air pollution etc. The consequences of climate change of Ethiopia are increase in the average temperature and the level of precipitation.
What is meant by climate change?Climate change is a long-term shift in global or regional climate patterns. Often climate change refers specifically to the rise in global temperatures from the mid-20th century to present. It results in the unexpected weather patterns and the change in the same making it quite unpredictable. It has been connected with other damaging weather events such as more frequent and more intense hurricanes, floods, downpours, and winter storms.
What are the Causes of Climate Change?More than 85 percent of emissions are due to agriculture and deforestation, while the power, transport, industrial and building sectors contribute 3 percent each. Globally, Ethiopia accounts for less than 0.1 percent of emissions, yet it is already experiencing the adverse effects of climate change. The major reasons or the causes of climate change in Ethiopia is rapid deforestation, rapid population growth and agricultural expansions, along with air pollution etc.
What are the Consequences of Climate Change?Climate change is expected to increase heatwaves, droughts, flooding, and sea levels around the world, and also cause important health risks in Ethiopia. Ethiopia is vulnerable to many of the effects of climate change, including increases in average temperature and changes in precipitation.
Discuss in detail about the population characteristics of Ethiopia?According to the 2022 revision of the World Population Prospects, the total population was 120,283,026 in 2021, compared to 18,434,000 in 1950.

- Calcite dissolves rapidly releasing visible bubbles of carbon dioxide gas so the acid test is useful for identifying if the mineral calcite is present.
- Luster is the way in which a mineral reflects light.
- Some minerals have a natural magnetism such as a magnetite which is why geologists test minerals with magnets to check for this characteristic.
- Pyrite has a metallic luster and is a yellowish mineral but it will not streak the same color as gold.
- Fluorescent minerals emite visible light when they are exposed to radiation.

Answers
The sentence that is not a true statement about mineral properties is option A. Calcite dissolves rapidly releasing visible bubbles of carbon dioxide gas so the acid test is useful for identifying if the mineral calcite is present. Hence, the correct answer is option A. Read below why option A. is the sentence that is not true of the minerals.
Why is option A not true?The bubbling release of carbon dioxide gas is so weak that one needs a hand lens to observe single bubbles slowly growing in the drop of hydrochloric acid - or so vigorous that a flash of effervescence is produced. This is the case as against the proposition stated in the option that it is visible whereas, it is not visible without a hand lens.
Therefore the correct answer is as given above.

Answer:
The statement "Pyrite has a metallic luster and is a yellowish mineral but it will not streak the same color as gold" is not a true statement about mineral properties.
In reality, pyrite, also known as fool's gold, does have a metallic luster and is often a brassy yellow color. However, when pyrite is streaked on a streak plate or any other rough surface, it leaves a greenish-black or dark gray streak, which distinguishes it from gold. Gold, on the other hand, leaves a golden-yellow streak.
Explanation:
The other statements you mentioned are true:
Calcite does dissolve rapidly in acid, releasing visible bubbles of carbon dioxide gas, which makes the acid test useful for identifying its presence.Luster refers to the way in which a mineral reflects light, and it is one of the important properties used in mineral identification.Some minerals, such as magnetite, exhibit natural magnetism, and geologists can use magnets to test for this characteristic.Fluorescent minerals do emit visible light when exposed to certain types of radiation, which is why they are used in fluorescent mineral displays.Remember that understanding the properties of minerals is crucial for their identification and classification in the field of geology.
Understanding the properties of minerals is an essential aspect of mineralogy and geology. Here are some additional details about mineral properties:
Hardness: Hardness is a measure of a mineral's resistance to scratching or abrasion. It is often assessed using the Mohs scale of hardness, which ranks minerals from 1 (softest) to 10 (hardest). For example, talc has a hardness of 1, while diamond has a hardness of 10.Cl34vage and Fracture: Cl34vage refers to the way a mineral breaks along planes of weakness, producing smooth, flat surfaces. Fracture describes the manner in which a mineral breaks when no cl34vage planes are present, resulting in irregular or rough surfaces.Color: Color can be a useful property for identifying minerals, but it can also be misleading. Many minerals exhibit a range of colors, while others may be colorless. Additionally, impurities within a mineral can cause variations in color.Streak: Streak refers to the color of a mineral's powder when it is scraped across a rough surface. It is often determined by rubbing the mineral on a streak plate, which is an unglazed porcelain tile. Streak color can differ from the mineral's external color and can aid in identification.Density: Density is the measure of a mineral's mass per unit volume. It helps distinguish between minerals with similar appearances but different compositions. Density is typically reported in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).Crystal Habit: Crystal habit refers to the characteristic shape and arrangement of crystals in a mineral. Different minerals exhibit distinct crystal habits, such as cubic, prismatic, tabular, or fibrous.Specific Gravity: Specific gravity is the ratio of a mineral's density to the density of water. It provides a measure of a mineral's heaviness compared to water and can aid in identification.These properties, among others, contribute to the identification and classification of minerals. It's important to note that some properties, such as luster and streak, are observable with the bare eye, while others, like hardness and specific gravity, may require specialized tools for accurate measurement.

Please explain!
Answers
High grade
Explanation:
Granite is converted into granitic gnesis in high grade of metamorphic phase The high grade refers to the temperature above 50°C or 323K around.Because increasing temperature decreases water crystals in graniteAnswer:
High Grade
Explanation:
The metamorphic grade responsible for the conversion of granite into granitic gneiss is generally high grade metamorphism.
Gneiss is a foliated metamorphic rock that is typically formed from the metamorphism of pre-existing rocks such as granite. During high grade metamorphism, the temperature and pressure conditions are high enough to cause recrystallization of the minerals in the parent rock, resulting in the formation of new minerals and the development of a foliated texture.
In the case of granite, high grade metamorphism can cause the feldspar and quartz grains to recrystallize and form elongated grains that are aligned parallel to the direction of greatest stress. This results in the development of a foliated texture that is characteristic of gneiss.
While low and medium grade metamorphism can also cause changes in the mineralogy and texture of rocks, they are generally not sufficient to produce the distinctive foliated texture of gneiss. Very low grade metamorphism typically results in the formation of non-foliated rocks such as quartzite or marble.
