What type of rock is formed from the cooling and hardening of lava or magma?

Front

What is chemical weathering?

Back

Chemical weathering is the process where rocks are broken down by chemical reactions, such as acid rain wearing away marble.

Front

What is an example of chemical weathering?

Back

A metal statue turning green after years of exposure to the elements is an example of chemical weathering.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process where rocks are physically broken down into smaller pieces without changing their chemical composition.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things.

Front

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

Front

What is an example of mechanical weathering?

Back

Frost wedging, where water freezes in cracks of rocks and expands, is an example of mechanical weathering.

Front

What is the role of water in weathering?

Back

Water can cause both mechanical and chemical weathering, breaking down rocks and dissolving minerals.
