Question

Name the different types of physical weathering.

Answer 1

1. Block Weathering - rocks crack due to temperature fluctuations.
2. Granular Weathering - different expansion rates of minerals cause rock to break into small pieces.
3. Exfoliation - outer layers peel off in concentric layers.
4. Frost Wedging - water freezes and expands in rock cracks, causing them to widen and break.
