What is root pry?

Back

Root pry is a type of weathering where plant roots grow into cracks in rocks, causing them to split apart.

What is mechanical weathering by animals?

Back

Mechanical weathering by animals occurs when burrowing organisms loosen soil and rock, pushing them to the surface for further weathering.

How do weak acids contribute to weathering?

Back

Weak acids, produced by lichens and moss, slowly dissolve rock, releasing nutrients and contributing to chemical weathering.

What is ice wedging?

Back

Ice wedging is a mechanical weathering process where water freezes in rock cracks, expands, and then thaws, causing stress and weakening the rock.

What causes chemical weathering from air pollution?

Back

Air pollution can lead to unusually acidic rain, which chemically weathers rocks by dissolving them.

Front

Define abrasion in the context of weathering.

Back

Abrasion is the process of weathering where rocks and soil are worn away by friction and impact from particles carried by wind, water, or ice.

Front

What is exfoliation in weathering?

Back

Exfoliation is a type of mechanical weathering where layers of rock peel away due to temperature changes and pressure release.

Front

Explain the role of carbonic acid in weathering.

Back

Carbonic acid, formed when carbon dioxide dissolves in water, can chemically weather rocks by dissolving minerals.

Front

What is oxidation in weathering?

Back

Oxidation is a chemical weathering process where oxygen reacts with minerals in rocks, often leading to rusting of iron-rich rocks.

Front

How do lichens contribute to weathering?

Back

Lichens produce weak acids that can slowly dissolve rock surfaces, aiding in chemical weathering and nutrient release.
