The real edge of a continent under the water
Richter
The amount of damage caused
In the North
Based on evidence, cannot be proven
The plates grind past each other, get stuck, build pressure, and release
Shield
Focus is under the crust, epicenter is directly above it.
Where the magma collects.
Mantle- solid but flows like liquid
In current positions, metals in rocks do not point to a common north, but if you put them together, they do.
Convergent
At plate boundaries
A type of tephra
The crust
2 cm/year
Mantle, crust
Two plates colliding under water. Forms island arcs.

Asthenosphere
