Aesthenosphere
San Andreas fault is an example of a ______________________boundary
Transform Plates slip by one another
Temperature and pressure ________ as you go deeper into the Earth
increase
In this type of boundary the older denser oceanic crust dives below the oceanic crust, heats up, and melts -- finds a weak spot in the crust resulting in a volcano.
Oceanic/Oceanic continental crust Example Japan
In this type of boundary the older dense oceanic crust dives below the continental crust. The oceanic crust will melt and push up through a weak spot in the continental crust form a volcano.
Continental/oceanic convergent boundary Example-Cascade Mountains
