Question

Which statements about the cycle of weathering, erosion, and deposition are true? Check all that apply.

1) Deposition leads to the breakdown of mountains.
2) Erosion occurs even when mountains are forming.
3) Gravity does not affect the rate of erosion.
4) When new mountains or plateaus form, the cycle starts over.
5) Weathering, erosion, and deposition have almost leveled Earth's riverbank.

Answer 1

Deposition does not lead to the breakdown of mountains. Erosion occurs even when mountains are forming. Gravity affects the rate of erosion. When new mountains or plateaus form, the cycle of weathering, erosion, and deposition starts over. Weathering, erosion, and deposition do not level Earth's riverbank.

Step-by-step explanation:

1) Deposition does not lead to the breakdown of mountains. Deposition is the process by which sediments are dropped or laid down in a new location. It does not cause the breakdown of mountains, but rather contributes to the formation of new landforms, such as deltas and floodplains.

2) Yes, erosion can occur even when mountains are forming. Erosion is the process of wearing away and transporting sediments. It can occur due to various factors like wind, water, and ice, regardless of whether mountains are being formed or not.

3) No, gravity definitely affects the rate of erosion. Gravity plays a crucial role in the movement of sediments down slopes, determining the speed and direction of erosion.

4) Yes, when new mountains or plateaus form, the cycle of weathering, erosion, and deposition starts over. The process of mountain building is called orogenesis, during which weathering and erosion wear down existing land while deposition builds up new landforms.

5) Weathering, erosion, and deposition have not leveled Earth's riverbank. These processes help shape the Earth's surface, but they do not level riverbanks completely. Over time, they may erode and deposit sediments, causing changes in the shape and form of riverbanks, but they do not lead to complete leveling.
