What can you infer about ice?
It usually causes chemical weathering.
It expands as it freezes.
It barely causes weathering at all.
It does not exert pressure on rocks.
How is mechanical weathering different from chemical weathering?
Chemical weathering happens over a much shorter time frame than mechanical weathering.
Chemical weathering occurs in the tropics; mechanical weathering occurs in temperate climates.
Chemical weathering occurs in mountains; mechanical weathering occurs on flat surfaces.
Chemical weathering changes the chemical composition of materials; mechanical weathering does not.
How does freezing water cause the weathering of rocks? The freezing water—
keeps the rocks in place
makes the rocks last longer
expands, cracks, and breaks rocks
causes rocks to fall in landslides
Grinding away of rock by rock particles carried by wind, water, ice and gravity is
abrasion
gravity
carbon dioxide
thermal expansion (temperature)
When water and oxygen cause a chemical reaction in iron to form rust (iron oxide).
