Apr 24, 2024 · Weathering describes the breaking down or dissolving of rocks and minerals on the surface of Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Weathering is the deterioration of rocks, soils and minerals (as well as wood and artificial materials) through contact with water, atmospheric gases, sunlight, and biological organisms. It occurs in situ (on-site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as ...
Jul 11, 2024 · weathering, disintegration or alteration of rock in its natural or original position at or near the Earth’s surface through physical, chemical, and biological processes induced or modified by wind, water, and climate.
Physical weathering is also referred to as mechanical weathering. It is the weakening of rocks followed by disintegration due to the physical or mechanical forces including the actions on the rocks by abrasion, frost chattering, temperature fluctuations and salt crystal growth.

Weathering is traditionally subdivided into two sets of processes: chemical weathering, the chemical decomposition of some or all of the constituent minerals or the bedrock. physical weathering, the mechanical breakdown or disintegration of the bedrock itself into particles large and small.
Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition.
