What are folds?Show answer
A fold is a bend in originally flat (horizontal) beds, produced by compression. The two basic folds are:
What are faults?Show answer

What is q1?Show answer
State which type of stress produces folds and which produces normal faults. [2 marks]

Describe the relative movement of the hanging wall in a reverse fault and what it does to the crust. [2 marks]
