Convergent Boundary
- Convergent plate boundaries are places where lithospheric plates are moving towards one another.
- Plates only move a few centimeters every year so collisions are slow and can last millions of years.
- When the plates collide the result can vary from earthquakes, volcanic activity, and deformation of the crust.
- Are convergent boundaries dangerous places to live in?
- Millions of People live and visit beautiful mountain ranges being built by plate collisions.
Eg. Rocky's, Alps, Himalayas.
- Each year thousands of people are killed by earthquakes and volcanic eruptions in those areas.
- Although, earthquakes and volcanic eruptions occurring in places where no one lives doesn't harm
anybody.
- If you choose to live in convergent plate boundaries, you can build houses that can withstand
earthquakes, and you can evacuate areas around volcanoes when they are about to erupt.
- Convergent plates boundaries are dangerous places to live although we can somewhat lessen the
danger.

Oceanic-Continental Convergence
- When an oceanic plate collides with a continental plate, the oceanic plate is pushed below the continental plate.
- When the oceanic plate pushes the continental plate up it can become a mountain.
- The place where an oceanic plate goes down under into the mantle is called the subduction zone.
- When the subduction zone is along an oceanic-continental boundary, it creates a deep-sea trench.
- Volcanoes can also be created by oceanic-continental convergence.
- High temperatures cause rocks to melt around the oceanic plate during the time when it's going
under the continental plate.
- When the magma is formed it is pushed through the upper plate forming volcanoes.
- This is how many volcanoes and mountain ridges are formed.

Oceanic-Oceanic Convergence
- When two oceanic plates collide the older, colder, and denser one bends and sinks into the mantle.
- Magma then rises to create volcanoes and new crust.
- When two oceanic plates collide it could also create deep-sea trenches like Challenger Deep.
- Challenger Deep is more than two kilometers larger than Mount Everest.

Continental-Continental Convergence
- When two continental plates collide neither are subducted.
- Instead they crumple up and tall mountain ranges form.
- Earthquakes are commonly found at these convergent boundaries.
- Volcanoes are not formed at continental-continental boundaries.
