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.)

What is a zeugen?
Rock masses are composed of horizontal layers of hard & soft rocks. Mechanical weathering causes the opening of such joints on the rock surface. Wind abrasion through the joints wear away the softer rocks & form grooves & fissures, while the harder rocks stand above as ridges. These features are known as Zeugen, which are common in Soneran Desert of U.S.A.
