Sci 8 Earth's Surface HW #2

Rocks along a riverbed that are smoothed from continuously moving water and sediment rubbing against them is an example of:

• physical weathering

• chemical weathering

A piece of sandstone changing color (from brown to rusty red) from exposure to water and air is an example of:

• physical weathering

• chemical weathering

Lichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of:

• physical weathering

• chemical weathering
