Title: Does the type of plate boundary determine the magnitude of earthquakes?
Question: Does the type of plate boundary determine the magnitude of
earthquakes?
Hypothesis: If we compare the magnitude of earthquakes at convergent and
divergent boundaries, earthquakes at convergent boundaries will have a
greater magnitude because there is greater kinetic energy released when two
plate boundaries collide.
IV: Type of plate boundary where earthquakes occur.
No control
Convergent
(Aleutian
Trench)

(Mid-Atlantic
Ridge)
