One sample question with the full working. 3 more in the app, with instant feedback and repair sessions for the traps below.

Which of the following is a type of chemical weathering?

Aexfoliation
Bcarbonation
Cfrost action
Dabrasion

Show the answer and working

Answer: B

Carbonation = chemical.

Trap A Confuses weathering, erosion and mass wasting: Weathering breaks rock IN PLACE. Mechanical: exfoliation, frost action. Chemical: carbonation (limestone), oxidation, hydrolysis. Erosion involves transport by agents.

Trap C Picks a closely related feature or term: Learn related features as contrasting pairs: how each forms and what it looks like.

Trap D Credits a landform to the wrong agent: Link each landform to its agent and process: ox-bow lake – river meanders; mushroom rock – wind abrasion; U-shaped valley – glacier; Lake Volta – a dam.

Traps in Weathering

Confuses weathering, erosion and mass wasting
Weathering breaks rock IN PLACE. Mechanical: exfoliation, frost action. Chemical: carbonation (limestone), oxidation, hydrolysis. Erosion involves transport by agents.
Picks a closely related feature or term
Learn related features as contrasting pairs: how each forms and what it looks like.
Credits a landform to the wrong agent
Link each landform to its agent and process: ox-bow lake – river meanders; mushroom rock – wind abrasion; U-shaped valley – glacier; Lake Volta – a dam.
Reverses the process or effect
Trace the cause and effect step by step and check the direction at each step.
Gives only part of the answer
Recall the full definition or list of factors and check the option covers it.
