GENERAL GEOLOGY

Detailed explanation-1: -Physical weathering, also called mechanical weathering or disaggregation, is the class of processes that causes the disintegration of rocks without chemical change.

Detailed explanation-2: -Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth’s surface.

Detailed explanation-3: -Chemical weathering is the dominate weathering process in warm, humid environments. It happens when water, oxygen, and other reactants chemically degrade the mineral components of bedrock and turn them into water-soluble ions which can then be transported by water.

Detailed explanation-4: -The weathering of rocks occurs through both physical and chemical processes. Physical weathering is the breakdown of rock into smaller pieces without altering the chemical composition of the rock.

Detailed explanation-5: -Physical, or mechanical, weathering happens when rock is broken through the force of another substance on the rock such as ice, running water, wind, rapid heating/cooling, or plant growth. Chemical weathering occurs when reactions between rock and another substance dissolve the rock, causing parts of it to fall away.
