Earthquakes and volcanoes

At least ____ seismographs are needed to accurately locate an earthquake epicenter.

• two

• five

• four

• three

Along a(n) ____ fault, rock above the fault surface moves upward in relation to rock below the fault surface.

• normal

• reverse

• elastic

• strike-slip

A normal fault occurs where forces pull two blocks of rock apart. At which kind of plate boundary does this occur? Why?

• . convergent plate boundary - This is where plates are coming closer together.

• convergent plate boundary - This is where plates are moving apart.

• divergent plate boundary - This is where plates are moving apart.

• divergent plate boundary - This is where plates are coming closer together.
