His is the geologic process of breaking down rocks into smaller and smaller pieces. There are two main types: chemical and mechanical. A) weathering
B) erosion
C) Deposition

Weathering

Explanation:

The geologic process of breaking down rocks into smaller and smaller units or pieces is known as weathering.

The physical disintegration and chemical decomposition of rocks to form sediments and soils is known as weathering.

The agents of weathering are wind, water and glacier.

Therefore, weathering breaks down rocks.

Erosion removes the weathered materials.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
