What Is Weathering? Weathering is the process that breaks down rocks into smaller and smaller pieces Weathering wears down mountains and breaks down statues.

Frost Action That process occurs when the water inside of rocks freezes and expands. That expansion cracks the rocks from the inside and eventually breaks.

WEATHERING: breakup of rock due to exposure to processes that occur at or near Earth’s surface TWO TYPES: Mechanical (physically) Chemical (chemically)

Chemical and/or Physical breakdown of rock Physical Weathering (mechanical) breakdown of rock into smaller pieces –Does not involve a chemical change.
