Weathering and Erosion

The breakdown of rock at or near the earth's surface Weathering
When rock is actually broken or weakened physically Mechanical Weathering
Alters a rock's chemical makeup by changing the minerals that form the rock, or combining them with new elements. Chemical Weathering
Chemicals in the polluted air combine with water vapor and fall back to earth Acid Rain
Is the movement of weathered materials such as gravel, soil, and sand. Erosion
Water expands when it freezes, the ice widens the crack and eventually splits the rock Frost Wedging
One of the major causes of erosion, expecially in areas with little water and few plants to hold soil in place. The Dust Bowl was an example. Wind Erosion
The greatest cause of erosion. Moving water--rain, rivers, streams and oceans. Water Erosion
Huge slow moving sheets of ice. Move over many years as layers of unmelted snow are pressed together Glaciers
The reaction of Iron and Oxygen. Rust
