What happens when friction between the opposite sides of a fault is high?
a.
a plateau may form on one side of the fault.
b.
the fault locks, and stress builds up until an earthquake occurs.
c.
folding of the crust may occur.
d.
the rocks on both sides of the fault easily slide past each other.

The answer is B. As the two sides of the fault move against each other, they might get stuck at a point. Therefore as they try to continue moving, and cannot, stress builds up between the two. When the energy builds up too high, the point at which they are stuck may immediately release or break, hence releasing a huge wave of energy from the point of release to form an earthquake. This point is usually referred to as the epicenter of the earthquake.
