What is weathering?

Back

Weathering is the process of breaking down rocks into sediment.

Front

What causes physical weathering?

Back

Physical weathering is caused by mechanical processes such as abrasion, freeze-thaw cycles, and root growth.

Front

What is abrasion in the context of weathering?

Back

Abrasion is the process of rocks and sediment grinding against each other, leading to the physical breakdown of materials.

Front

What is ice wedging?

Back

Ice wedging is a type of physical weathering that occurs when water seeps into cracks in rocks, freezes, and expands, causing the rocks to break apart.

What role do tree roots play in weathering?

Back

Tree roots can grow into cracks in rocks, exerting pressure and causing the rocks to break apart, contributing to physical weathering.

How is carbonic acid formed in nature?

Back

Carbonic acid is formed when water combines with carbon dioxide, which can lead to chemical weathering of rocks.

What is the difference between physical and chemical weathering?

Back

Physical weathering breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the minerals within the rocks.

Front

What is permeability in relation to weathering?

Back

Permeability refers to the ability of a material to allow fluids to pass through it, which can influence weathering processes.

What is an example of weathering caused by acid rain?

Back

Acid rain can chemically weather limestone and marble, leading to the dissolution of these rocks.
