Multiple Choice

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

• convergent, this is where plates are coming closer together

• convergent, this is where plates are moving apart

• divergent, this is where plates are moving apart

• divergent, this is where plates are coming together

Normal Fault

divergent, this is where plates are moving apart
