How do observations of earthquake and volcanic activity support the theory of plate tectonics?

1 answer:

3 0

They provide evidence that movements of the crust are a result of slow moving currents in the mantle. Since earthquakes and volcanic eruptions are usually a result of stick-slip movements between 2 more plates and it is tension changes that are responsible for this sudden movement, the plates must be moving overtime or this tension would remain fairly constant.
