Physical Weathering

Question 1

Frost shattering

Answer 1

Freeze-thaw weathering

Question 2

Salt crystallisation

Answer 2

The salt forms into crystals through evaporation, as they grow they exert pressure within the rock causing it to crack

Question 3

Wetting and drying

Answer 3

This happens in the tidal zone and where the clay are present and are expanding and contracting which causes the rock to weaken

Question 4

Solution

Answer 4

Involving the dissolving of soluble minerals particularly limestone and chalk, the effect of it is to enlarge joints in the rocks creating jagered rock surfaces

Question 5

Biological action

Answer 5

Involving marine organisms, they have adapted to break rocks especially chalk

Question 6

Chemical weathering

Answer 6

Tend to occur in either wetting and drying and or the bottom of slopes where material and moisture often accumulates.
