What are the three processes to mechanical weathering?

Answer 1

The processes for mechanical weathering are what change the rock completely. In chemical, it's what changes the rock into something different.

For mechanical, there are four types of weathering.

1) Abrasion: Sand and rock particles are carried by wind, water or ice and wear away exposed rock surfaces.

2) Exfoliation: (heating and cooling of the rock)

3) Bioturbation: * roots of trees and other plants enter cracks in rocks and eventually break them. * An animal that burrows in the ground.

4) Frost action/ ice wedging: When water enters a rock and freezes which makes the rock expand and therefore, make the crack bigger. (Think of this like snow and ice and the side walks.)

Answer 2

the three types of mech. weather are organic matter,ice wedging, and abrasion

Answer 3

Chemical Weathering, Physical Weathering, and Mechanical Weathering

Answer 4

Weathering, erosion, and deposition. Earth's surface could also be built up by volcanism.

Answer 5

ice wedging,pressure release, plant root growth,and abarsion.
