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.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
