1. Plate Tectonic Study Guide

2. Convergent with subduction
Oceanic plate is colliding with another oceanic plate and the denser plate is subducting.
Volcanic Island arc are formed
Hot Spot
Plate is sliding over a weak spot on the crust and magma is breaking through
Volcanic Island

3. Convergent boundary with suduction
Continental plate collides with an oceanic plate and the oceanic plate subducts.
Volcanic Mountain chain on continental plate
Divergent boundary
Two plates are moving away from each other.
Mid-ocean ridge, new crust, and rift valley(forms on land).

4. Along mid-ocean ridges and where a plate is subducted.
Transform boundary
Two plates slide past each other in opposite directions.
Earthquakes No No
Convergent without subduction
Two continental plates are colliding.
Mountains
Along mid-ocean ridges and where a plate is subducted.

5. Plate movement happens slowly on a global scale.
The heating and cooling of magma in the mantle.
Pushes lithospheric plates
Hot magma rises
Cool magma sinks
At transform boundaries because the plates just slide past each other.
Earthquakes

6. Both Earth’s climates and surface features have changed over time.
As the two plates separate magma fills in the gap and forms new crust.
When two continental plates collided it pushed up the fossils from the oceanic crust to the top of the mountains that it formed.
They would need to build them strong enough to withstand earthquakes.
