Difference Between Physical and Chemical Weathering

Jun 08, 2012· What is Physical Weathering? Physical weathering is also called as mechanical weathering. This is the process where rocks breakdown without altering their chemical composition. Physical weathering can occur due to temperature, pressure or snow. There are two main types of physical weathering. They are freeze thaw and exfoliation.

What Is Chemical Weathering? ThoughtCo

Feb 18, 2019· Chemical weathering does not break rocks into smaller fragments through wind, water, and ice (that's physical weathering). Nor does it break rocks apart through the action of plants or animals (that's biological weathering). Instead, it changes the chemical composition of the rock, usually through carbonation, hydration, hydrolysis or oxidation

Weathering Wikipedia

Physical weathering. Physical weathering, also called mechanical weathering or disaggregation, is the class of processes that causes the disintegration of rocks without chemical change.The primary process in physical weathering is abrasion (the process by which clasts and other particles are reduced in size). However, chemical and physical weathering often go

Examples of Physical Weathering YourDictionary

Physical weathering is a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition. Over time, movements of the Earth and environment can break apart rock formations, causing physical weathering. Physical weathering can also refer to other things in the environment breaking down, like soil and
