Weathering Notes

Weathering: Breaking of rocks into Piece - Sediment

Mechanical Weathering: Crushing of Rocks.

Chemical Weathering: Dissolving of Rocks.

6 Types of Weathering• 1. Water• 2. Plants• 3. Wind• 4. Temperature Change• 5. Gravity• 6. Glaciers

1. Weathering by Water:- Water pounds on rock, or grinds rock with sediment causing it to break.- Water freezes in the cracks of rocks. Expands and cracks the rock.- Water dissolves the minerals out of rocks causing them to weaken and break.

2. Weathering by Plants: Plant roots grow in rocks causing the rocks to crack.

3. Wind Weathering: Carries sediments that get blown into other rocks causing them to chip & break.

4. Temperature Change causes Weathering:Expansion and contraction from temperature change weakens and cracks rocks.

5. Weathering by Gravity:The pull of gravity can weaken and crack the rocks.

6. Glaciers Cause Weathering:Weight of glaciers scratch and crack rocks.
