Normal faults are
associated with forces that push rocks together
a type of strike-slip fault
associated with anticlines and synclines
produced by shearing tectonic forces
associated with tensional tectonic force

Normal faults are ​associated with tensional tectonic force.

Explanation:

A Fault , in geology represents a planar fracture in a rock , there can be large faults , which are formed by the action of the tectonic forces , even the rapid movement of these tectonic plates on any active fault can lead to an earthquake.

There are two types of fault possible ,  

Normal fault and Reverse fault.

In a normal fault , the hanging wall moves in downward direction with respect to the footwall , and , in reverse faults, the footwall moves in downward direction with respect to the hanging wall.

developed countries have tended to improve the environment, while developing countries have tended to damage it.
