List the 3 types of tectonic plate boundaries
What is convergent, divergent, transform
100
How are compression and tension different
What is compression squeezes together while tension pulls rocks apart
200
_______ _______ are Pieces of the lithosphere that move around on top of the asthenosphere
What is tectonic plates
200
Which layer of the Earth contains most of the Earth's mass
What is mantle
200
What is the name of the single landmass that is now our 7 continents
What is Pangea
200
What type of tectonic plate boundary is associated with earthquakes
What is transform boundary

What is the difference between folding and faulting
What is folding is when the rock layers bend and fold but do not break, a fault is when the rock layer is stress enough to where a break occurs and the layer slide past each other

How do scientist know about the Earth's interior?
What is through underwater volcanos and the molten rock that flows from them

Name 2 examples of evidence that helps prove the continental drift theory
What is animal fossils, plant fossils, glaciers, sea-floor spreading

What type of stress occurs during a reverse fault
What is compression
500
_____ _______ ______ is the process by which new oceanic lithosphere is created as older materials are pulled away
