6. the breaking down and changing of rocks at or near earth's surface is called
a sheet erosion
b uplift
c weathering
d mass movement

The correct answer is C. Weathering

Explanation:

The term "weathering" refers to the breaking down or alteration of rocks, minerals and similar that are on the surface. This occurs due to different factors such as physical forces for example pressure or air; chemical reactions such as extreme temperatures or due to organisms. Additionally, weathering leads to changes on rocks and in general terms on soil and the surface. Also, this differs from erosion because it does not imply the movement of oil or rocks but occurs in one place. According to this, it is weathering the term that describes the breaking down and changing of rocks.
