Answer:
C. terrigenous sediments
Explanation:
In oceanography, terrigenous sediments are those derived from the erosion of rocks on land; that is, they are derived from terrestrial (as opposed to marine) environments
The oozes on the seafloor mostly consist of ____.
The oozes on the seafloor mostly consist of biogenic sediments such as calcium carbonate (from shells of marine organisms) or silica (from the remains of diatoms).
Oozes are deposits of sediments that accumulate on the ocean floor. These sediments are typically composed of the remains of dead marine organisms, such as shells, skeletons, and other organic matter, that have settled on the ocean floor over time. Oozes are named according to their predominant composition, such as calcareous ooze, siliceous ooze, or red clay, which is primarily composed of fine-grained clay particles. The distribution of oozes across the ocean floor is influenced by various factors, such as water depth, temperature, and nutrient availability, which affect the types of organisms that live in the ocean and contribute to the sediment. Oozes play an important role in the global carbon cycle and the formation of deep-sea ecosystems, as well as in the study of past climate and ocean conditions through the analysis of sediment cores.

dissolved ions freed during the process of metasomatism can precipitate to form mineral-filled cracks called veins
true or false
True. Dissolved ions that are freed during the process of metasomatism can precipitate to form mineral-filled cracks called veins.
Metasomatism is a geological process that involves the alteration of a rock's chemical composition due to the introduction of fluids that contain dissolved ions. These fluids can react with the minerals in the rock, causing some minerals to dissolve and others to precipitate. When minerals precipitate from these fluids, they can form veins or other types of mineral deposits within the host rock. These veins can be filled with a wide variety of minerals, depending on the specific conditions and the nature of the host rock. Veins can be an important source of valuable minerals and ores, and their formation is an important process in many geological settings.

What happens when a stream overtops it's banks during a flood? (what is the velocity and how does it change)
When a stream overtops its banks during a flood, it means that the water level in the stream has risen above the level of the surrounding land. This can happen when there is too much water in the stream, such as during heavy rain, snowmelt, or other weather events.
As the stream overtops its banks, the velocity of the water slows down. This is because the water is no longer confined to the narrow channel of the stream and is instead spreading out over a wider area. When the water spreads out, the friction between the water and the land surface increases, which causes the water to slow down.
As the velocity slows, the stream's carrying capacity decreases, which means that it can no longer transport as much sediment and debris as it could when it was flowing at a faster rate. This can cause sediment deposition and the formation of levees along the stream banks.
In extreme cases, when the stream overtops its banks, it can cause flooding in nearby communities and cause damage to homes, buildings, and infrastructure. This is why it is important for communities to be prepared for floods and have plans in place to evacuate residents and protect property.
Overall, when a stream overtops its banks during a flood, the velocity of the water slows down, which can lead to sediment deposition and the formation of levees. It can also cause flooding and damage to nearby communities if precautions are not taken.

Air flow is initiated by different forces including the pressure gradient force, Coriolis force, and friction force.
Explanation:Air flow is initiated by the pressure gradient force. This force occurs when there is a change in pressure over a distance. For example, air flows from an area of high pressure to an area of low pressure.
The Coriolis force is a force that is experienced due to the rotation of the Earth. It affects the motion of objects, including air flow, causing them to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
The friction force can also initiate air flow. When air molecules come into contact with a surface, such as the ground or a solid object, their movement is slowed down due to friction.

Exfoliation Dome
sheeting, where concentric slabs of rock break loose in reaction to the unloading of pressure.
Exfoliation domes are geological features characterized by large, rounded rock formations that appear to be peeling away in layers like an onion.
They are typically found in areas with large expanses of exposed bedrock, such as mountain ranges and deserts. The process by which exfoliation domes form is known as sheeting, which is a type of mechanical weathering caused by the unloading of pressure on the surface of the rock.
Sheeting occurs when the pressure that has been holding a rock mass together is reduced. This can happen as a result of erosion, uplift, or other geological processes.
As the pressure is released, the rock begins to expand and crack, leading to the formation of concentric slabs or sheets of rock that are separated by joints or fractures. Over time, these slabs can break loose from the underlying rock and peel away, creating the characteristic dome-like shape of an exfoliation dome.
The formation of exfoliation domes can have important implications for geological processes and human activities. For example, exfoliation can create unstable rock formations that are prone to rockfall and landslides, which can pose a danger to people and infrastructure.

a gas that can reach the upper atmosphere after a large-scale volcanic eruption
A gas that can reach the upper atmosphere after a large-scale volcanic eruption is sulfur dioxide (SO2).
During volcanic eruptions, various gases are emitted, including water vapor, carbon dioxide, and sulfur dioxide. Among these gases, sulfur dioxide plays a significant role in impacting the atmosphere and climate.
When a large-scale volcanic eruption occurs, vast amounts of sulfur dioxide are released into the atmosphere. Due to the explosive nature of the eruption, this gas can be propelled high into the stratosphere, which is the second layer of Earth's atmosphere, located above the troposphere.
In the stratosphere, sulfur dioxide reacts with water vapor to form tiny sulfuric acid droplets known as aerosols. These aerosols can stay suspended in the upper atmosphere for months to years, depending on the size of the eruption and the amount of sulfur dioxide released.
These aerosols have a cooling effect on Earth's climate because they reflect incoming sunlight back into space, reducing the amount of solar energy that reaches the Earth's surface. This can lead to a temporary drop in global temperatures, which has been observed following major volcanic eruptions such as the 1991 eruption of Mount Pinatubo in the Philippines.
In summary, sulfur dioxide is a gas that can reach the upper atmosphere after a large-scale volcanic eruption. Its presence in the stratosphere leads to the formation of sulfuric acid aerosols, which can reflect sunlight and contribute to a temporary cooling effect on Earth's climate.

P-wave arrives 3 minutes 19 seconds before an S-wave, how far away is the epicenter from the point where the time-difference in wave arrival was measured?
The epicenter is approximately 298.5 kilometers away from the measuring point.
To determine the distance of the epicenter from the point where the time-difference in wave arrival was measured, we can use the time difference between the arrival of P-wave and S-wave and the knowledge of their velocities.
Since P-waves travel faster than S-waves, we can assume that the P-wave arrived first, followed by the S-wave. The time difference between the two waves is 3 minutes and 19 seconds, or 199 seconds.
The speed of P-waves through the Earth's crust is approximately 6 kilometers per second, while the speed of S-waves is approximately 3.5 kilometers per second. Using the formula distance = velocity x time, we can calculate the distance of the epicenter from the measuring point as follows:
distance = (velocity of P-wave - velocity of S-wave) x time difference
distance = (6 km/s - 3.5 km/s) x 199 s
distance = 1.5 km/s x 199 s

In July, isotherms in the Northern Hemisphere shift toward the poles over land since higher temperatures occur in continental interiors.
T or F
The given statement " In July, isotherms in the Northern Hemisphere shift toward the poles over land because higher temperatures occur in continental interiors." is true because the continental interiors are farther from the moderating influence of the oceans, causing temperatures to be higher.
During the summer months, the landmasses in the Northern Hemisphere heat up faster than the oceans, creating a temperature gradient that causes warm air to rise over the land and cool air to sink over the ocean. This creates a high-pressure zone over the ocean and a low-pressure zone over the land, which draws in moist air from the oceans.
As this moist air is lifted over the continents, it cools and releases its moisture, creating a band of precipitation along the boundary between the land and ocean. This band is known as the Intertropical Convergence Zone (ITCZ).

When using longitudinal lines, convergence towards the ______ must be taken into consideration.
When using longitudinal lines, convergence towards the poles must be taken into consideration.
Longitudinal lines, also known as meridians, run from the North Pole to the South Pole and converge as they approach the poles. This convergence is an important consideration for accurate mapping and navigation.
When creating maps that cover large areas, it is essential to adjust for the convergence of longitudinal lines towards the poles. Otherwise, the resulting map will be distorted, and accurate measurements or navigational calculations cannot be made. This convergence effect becomes more significant as one moves toward the poles, making it more critical to adjust for it when working with maps or models that cover high latitudes. To account for the convergence effect, cartographers use a technique called conformal projection, which preserves the shape of features on the map while distorting their size and distance from each other.
