Continental Drift
True or False: Continental Drift is a theory that is still very unlikely according to scientists.
False
What happens to the tectonic plates during a convergent boundary?
The more dense plate slides beneath the less dense plate
What is a divergent boundary 'filled up' with?
Magma from the mantle
True or False: Transform Boundaries cause volcanoes
Which boundary causes the most earthquakes
Transform
What is the huge landmass that was on Earth before the continents split up?
Pangea
Which plate is more dense: a Continental Plate or a Oceanic Plate?
Oceanic Plate
What happens as a divergent boundary occurs?
