The Earth is made up of many plates that are:

• Moving in different directions at different rates

• Always in the same position and don't move.

• Stuck together in some places but move in others

• All moving away from each other

We have only been able to drill a few miles below the surface of the Earth because:

• There are road blocks in the way

• There is too much water

• We can't see past a few miles

• It's so hot the drill gets deformed and breaks

Deep below the earth's surface where it gets very hot, the rocks begin to:

• Crack

• Crumble

• Change Colors

• Creep

The movement of plates away from each other, causing a gap and often some kind of volcanic rock or activity to happen:

• Large mountains

• Mid-ocean ridge

• A trench

The movement of two plates pushing towards each other often causes

• A mountain to form

• An ocean to form

• A mid-ocean ridge
