17
Q

What is a destructive plate boundary?

A

Where two plates are forced into each other and the oceanic plate subducts under the continental plate. This causes large pressure build-up and high magnitude earthquakes.

18
Q

What is a conservative plate boundary?

A

Where two plates move alongside each other and rocks and other material gets caught together resulting in medium amounts of pressure build up.

19
Q

What is a constructive plate boundary?

A

Where two plates pull apart from each other, creating a ridge. Low amounts of pressure builds up and low magnitude earthquakes occur.
