Plate Tectonic Study Guide

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

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).

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.

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

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.
