Chemical weathering is the process by which rocks are broken down by the action of water, acids, and other chemicals.

Abrasion is the process of breaking down rocks into smaller pieces by the action of wind-blown sand and other particles.

Biological weathering is the process by which rocks are broken down by the action of living organisms, such as plants, animals, and microorganisms.

Exfoliation weathering is the process of breaking down rocks into smaller pieces by the action of temperature changes, causing the outer layers of the rock to flake off.

Mechanical weathering is the process by which rocks are broken down into smaller pieces by the action of pressure, such as the weight of overlying rocks or the movement of tectonic plates.

Frost wedging is the process of breaking down rocks into smaller pieces by the action of ice, which expands and contracts in cracks and crevices, causing the rock to break apart.

Chemical weathering is the process by which rocks are broken down by the action of acids, such as carbonic acid and nitric acid, which dissolve minerals in the rock.

Salt weathering is the process of breaking down rocks into smaller pieces by the action of salt, which crystallizes in cracks and crevices, causing the rock to break apart.

Biological weathering is the process by which rocks are broken down by the action of plants, which release acids that dissolve minerals in the rock.

Bioturbation is the process of breaking down rocks into smaller pieces by the action of animals, such as burrowing and digging, which exposes the rock to weathering agents.

Biological weathering is the process by which rocks are broken down by the action of microorganisms, such as bacteria and fungi, which release acids that dissolve minerals in the rock.

Deflation is the process of breaking down rocks into smaller pieces by the action of wind, which removes fine particles from the surface of the rock.

Mechanical weathering is the process by which rocks are broken down into smaller pieces by the action of gravity, such as landslides and rockfalls.

Abrasion is the process of breaking down rocks into smaller pieces by the action of waves, which carry sand and other particles that wear away the rock.

Mechanical weathering is the process by which rocks are broken down into smaller pieces by the action of glaciers, which scrape and grind the rock as they move.
