Plate Margins
- Conservative Plate Margin
- Two plates rubbing against each other in almost similar direction but at different angles and speeds.
- One is going faster than the other and eventually they get stuck.
- As they remain stuck, pressure builds up between the two plates causing them to move apart, releasing the pressure.
- This release in pressure causes an Earthquake.
- Two plates rubbing against each other in almost similar direction but at different angles and speeds.
- Destructive Plate Margin
- Oceanic crust subducts under continental crust
- Collision boundary
- This is when two continental plates collide head-on
- But instead of one sinking under the other, they buckle.
- This is when two continental plates collide head-on
- Collision boundary
- Friction and heat from mantle cause Oceanic crust to melt
- Pressure is exerted when Oceanic crust melts, this results in an Earthquake.
- Magma rises up and forms a volcano in the continental crust
- Oceanic crust subducts under continental crust
- Constructive Plate Margin
- In a constructive plate margin, the plates are moving apart.
- This means there is a gap where there once was solid land.
- Cracks and fissures begin to open up in the land and magma and ash make their way through.
- The magma then goes through to the atmosphere and ocean and this forms volcanoes.
- In a constructive plate margin, the plates are moving apart.
