Weathering and Erosion

The wind picks up all the smaller particles leaving behind only bigger rocks.

• Weathering
• Erosion

A rock hits another rock as it is carried downstream causing both rocks to break.

• Weathering
• Erosion

A rock is broken apart by the water in a crack that freezes and turns to ice.

• Mechanical Weathering
• Chemical Weathering

Water mixed with carbon forming carbonic acid that eats away at marble and limestone.

• Mechanical Weathering
• Chemical Weathering
