Mechanical (physical) weathering is the breakdown of rock into smaller particles due to such factors as freezing and thawing, release of pressure, water absorption, salt crystal formation, landmass uplift, expansion and contraction from the sun or fire, plant root growth, actions of animals, abrasion, or other means that do not directly affect the rock's chemistry.
yes, liquid water is a unit of chemical weathering. ice is a unit of physical weathering.
Chemical weathering is the type of weathering caused by chemical reactions in water. This process involves the breakdown of rocks and minerals through chemical reactions with water, leading to the alteration of the rock's composition. Examples of chemical weathering processes in water include hydration, hydrolysis, and oxidation.
Chemical and physical weathering both involve the breakdown of rocks into smaller particles. Both processes are influenced by factors like temperature, moisture, and the type of rock being weathered. Additionally, both types of weathering contribute to soil formation by breaking down rocks into mineral particles.
Chemical weathering occurs when limestone is dissolved by chemicals in water. This process, known as carbonation, is caused by the reaction of carbon dioxide in rainwater with the calcium carbonate in limestone, forming calcium bicarbonate which is soluble in water.
Oxygen is not a type of weathering. However, oxygen can play a role in certain types of chemical weathering processes, such as oxidation, where oxygen reacts with minerals in rocks to break them down.
If you meant weathering that is caused by water; physical weathering is the answer.
weathing
Frost action is a type of physical weathering caused by the expansion of water when it freezes and contracts when it thaws. This repeated freeze-thaw cycle weakens rocks and can lead to the breakdown of rock surfaces.
Frost wedging
Physical Weathering (aka Mechanical Weathering) is the main type of weathering in deserts.
Physical weathering is the breakdown of rocks into smaller pieces without changing their chemical composition. It is caused by factors such as temperature changes, abrasion from wind or water, and ice formation in cracks.
Four types of weathering that can occur without water include mechanical weathering caused by temperature changes, chemical weathering due to oxygen in the air, biological weathering from plant roots and burrowing animals, and physical weathering caused by wind abrasion.

Abrasion caused by particles in water is a type of physical weathering, where rocks are broken down into smaller pieces through mechanical processes like grinding and wearing down by abrasive particles.
