1. What makes weathering different from erosion?Weathering breaks down rock in place; erosion involves its removal.Weathering only happens at the coast.Weathering always involves moving water.

2. Why can repeated freezing and thawing widen a joint in rock?Ice dissolves the rock.Water expands as it freezes, exerting pressure on the joint.Cold water makes the whole cliff slide.

3. Which process is an example of chemical weathering?Rock fallSalt crystallisationCarbonation of limestone

4. What is the main driving force behind mass movement?GravityEvaporationPhotosynthesis

5. How does rotational slumping differ from sliding?Slumping only happens in dry rock.Slumping moves along a curved slip surface; sliding typically follows a flatter surface.Slumping is the chemical breakdown of rock.

6. Why can heavy rainfall make a slope less stable?It removes gravity.It always freezes the slope.It can add weight and increase pore-water pressure, reducing resistance to movement.
