- Oceanic plate collides with (meets) Continental plate
- The Oceanic plate is denser than the continental plate so it sink under the continental plate (Subduction)
- Creates volcanoes and Ocean Trenches
- Trenches: very deep sections of the ocean floor where the oceanic plate goes down
- Crust is DESTROYED
- Creates friction which then causes earthquakes
- Creates volcanoes and Ocean Trenches
- PLATE MARGINS
- Destructive
- Where two plates are moving TOWARDS each other

- Crust is DESTROYED
- Creates friction which then causes earthquakes
- Creates volcanoes and Ocean Trenches
- Conservative
- Where two plates are moving PAST each other
- OR moving the same direction but at different speeds
- Occur close to the Earth's surface and when occur can be very destructive
- Crust is never CREATED or DESTROYED
- Where two plates are moving PAST each other
- Constructive
- Where two plates are moving AWAY from each other
- Magma rises up from the mantle to fill the gap and cools
- New crust is CREATED
- Magma rises up from the mantle to fill the gap and cools
- Happens under the Atlantic Ocean along the Mid-Atlantic Ridge
- Where two plates are moving AWAY from each other
- Destructive
