Question

a fault is a break in earth's crust where rock movement occurs. what type of fault is produced by tension, where a block drops drops down in relation to the blocks around it

Answer 1

The type of fault produced by tension, where a block drops down in relation to the blocks around it, is called a **normal fault**. In a normal fault, the block of rock above the fault plane, known as the hanging wall, moves downward relative to the block below the fault plane, called the footwall. This occurs due to extensional forces that pull the crust apart.
