Weathering

Weathering and erosion both act on the surface of Earth. In what way is weathering similar to erosion?

• both are caused by freezing water

• wind and water are agents of both

• both move rocks

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

How do plants weather rocks?

• during photosynthesis

• when roots grow into cracks of rocks and expand the rock

• when the plant moves water from the roots to the leaves

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering

• chemical weathering

• erosion weathering

• deposition

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

• mechanical weathering

• chemical weathering

• erosion weathering

• deposition

How might a weathered mountain appear different than an unweathered mountain?

• Weathered mountain would be taller.

• Weathered mountain would be rounder and less jagged.

• Weathered mountain would be more jagged and less rounded.

• Weathered mountain would have no trees.
