the movement of rocks and soil is an example of
a erosion
b weathering
c deposition
how does alternate freezing and thawing of water cause weathering to occur?
a freezing chemically alters the rock surfaces

Explanation:

Erosion is the movement of rocks and soil by natural forces like water, wind, or ice. Weathering is the breaking - down of rocks in place, and deposition is the laying down of eroded material. Alternate freezing and thawing of water is a physical weathering process where water expands when it freezes, creating pressure that breaks rocks. It is a physical, not chemical, alteration.

Answer:

The movement of rocks and soil is an example of: A. erosion
How does alternate freezing and thawing of water cause weathering to occur? None of the given options are correct as it is a physical process of expansion and pressure, not a chemical alteration. If we assume the closest correct - type answer from the given ones is not provided, the key concept is physical break - down due to water volume change during freezing and thawing.
