1. The MAIN cause of increased erosion, especially for soil, is C) human activity.
To explain why human activity is the main cause of increased erosion, we can consider some examples. Human activities such as deforestation, construction, and agriculture often involve removing vegetation cover, which leaves the soil exposed to the forces of wind and water. This can lead to increased erosion as the wind can blow away loose soil particles and water can wash away the topsoil. Additionally, human activities may also involve the removal of natural barriers like trees and shrubs that help to protect the soil from erosion. Therefore, human activity is the primary factor contributing to increased erosion, particularly for soil.
To arrive at this answer, you can eliminate the other options by considering their relevance to erosion. Strong winds (option A) can contribute to erosion, but it is not the main cause, especially for soil erosion. Flash floods (option B) can lead to erosion, but they are not the primary cause. The movement of glaciers (option D) can cause erosion in certain regions, but it is not the main cause globally. Therefore, the correct answer is C) human activity.
2. The oceanic landform that is similar to a canyon is C) ocean trench.
To explain why an oceanic trench is similar to a canyon, we can compare their characteristics. Both canyons and ocean trenches are long, narrow, and deep depressions in the Earth's surface. Just as canyons are formed by the erosive action of rivers cutting through the land, ocean trenches are formed by tectonic plate activity where one tectonic plate is subducted beneath another. These processes create deep, narrow channels in the Earth's crust. Therefore, an ocean trench is the oceanic landform that is most similar to a canyon.
To arrive at this answer, you can eliminate the other options by considering their characteristics. A valley (option A) is a more general term for low-lying areas between hills or mountains, which can have various shapes and sizes. A seamount (option B) is an underwater mountain, but it lacks the long, narrow, and deep characteristics of a canyon. The mid-ocean ridge (option D) is a long underwater mountain range formed by diverging tectonic plates and is not similar to a canyon. Therefore, the correct answer is C) ocean trench.
3. The statement that does NOT describe how rocks may be weathered is B) rock pieces are moved from place to place.
To explain why rock pieces being moved from place to place does not describe weathering, we can discuss the process of weathering. Weathering refers to the breakdown, disintegration, or decomposition of rocks and minerals at or near the Earth's surface. It can occur through physical, chemical, or biological processes.
Options A, C, and D all describe different types of weathering processes. Water filling tiny spaces inside a rock (option A) can contribute to physical weathering through freeze-thaw cycles and the expansion of water. Plant roots growing between cracks in rocks (option C) can exert physical pressure on the rocks, leading to their fragmentation. Living things, like moss and lichens, chemically breaking down rocks (option D) is an example of biological weathering.
However, rock pieces being moved from place to place (option B) is not a process of weathering. While the movement of rock fragments, such as through erosion or transportation by wind or water, can result from weathering, it does not describe the weathering process itself. Therefore, the correct answer is B) rock pieces are moved from place to place.
