What are the two main types of weathering?

Back

The two main types of weathering are mechanical (physical) weathering and chemical weathering.

Front

What is mechanical weathering?

Back

Mechanical weathering is the physical breakdown of rocks into smaller pieces without changing their chemical composition.

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often leading to their breakdown.

Front

How do plant roots contribute to weathering?

Back

Plant roots can grow into cracks in rocks, exerting pressure and causing the rocks to break apart.

What role does water play in weathering?

Back

Water can seep into cracks in rocks, freeze, and expand, leading to mechanical weathering.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle, which is broken into tectonic plates.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer beneath the lithosphere that allows tectonic plates to move.
