see if you could step off
of a continent and walk
across the ocean?
The
Continental Shelf
What are 3 geologic
events/formation that
happen on Earth due to
plate tectonics?

True or False?
If convection currents
stopped moving it would
mean that the inner core is
no longer heating the

TRUE!
The heat from the inner core
heats the mantle. The

make the plates of the
lithosphere move slowly.
