100

A deep break or crack in the earth's surface alone which rocks can move

What is a fault 

200

Which type of fault movement do creation scientist think God used to create mountains, like the Himalayan mountains in Asia 

What is reverse faults

200

this type of fault happens when rocks move horizontally past each other.

What are strike-slip faults 

200

These waves are slow moving and are very destructive during an earthquake 

What are surface waves

200

this earthquake scale measures the magnitude of the earthquake

What is Pangaea 

500

This fault occurs at plate boundaries and as rocks move apart, a section of the rock my fall creating a separation between the plates
