Question

Explain in detail normal faults.

Answer 1

The term, 'normal fault' actually comes from coal mining, but more about that later. A fault, which is a rupture in the earth's crust, is described as a normal fault when one side of the fault moves downward with respect to the other side. The opposite of this, in which one side moves up, is called a reverse fault. To remember what a normal fault is, think about it this way: it seems more normal for earth to slide down (because of gravity) than it is for it to go up. Earth moving down is normal; moving up is reverse.

Answer 2

A normal fault is a geological fault in which hanging wall has moved downward to the relative footwall, they occur when 2 blocks of rocks are pulled apart as by tension.
