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.
