Weathering Rocks

And what causes them
Weathering Rocks
By: Jaime Lister

Rock Weathering
It breaks into soil, sand, silt, clay, and smaller pieces of rock.

Causes of Weathering
Rain
Ice Wedging
Plants
Acids
A mechanical type of weathering. The cycle of ice freezing and then thawing, breaks up rock.
Plants weather rocks by growing into cracks or rocks where they find nutrients. When the roots grow, they wedge the rocks apart.
Naturally formed acids can weather rocks chemically. Carbonic acid reacts with minerals such as calcite which causes the rock to weather.
