Weathering

When you see rock split, broken or crumbling, you see weathering. Dissolving, rusting and dulling are also forms of weathering.

Look at some types of weathering.

Lichen grows on rocks causing them to crumble into bits.

A waterfall is carving away the rocks beneath it over a
long period of time.

Acid rain is breaking down the sidewalk.

Rain and oxygen are causing some of the rocks in a
canyon to turn red in color.

A glacier carves lines into Earth’s surface as it moves

Ice gets in the cracks of a rock, freezes and expands
which cracks the rock apart.
