TECTONIC PLATE INTERACTIONS

There are 3 types of tectonic plate interactions.

Divergent Boundary- plates move away from each other create new rock with volcanoes rift zone examples Mid-Atlantic Ridge & Great Rift Valley in eastern Africa earthquakes

Convergent Boundary- plates collide, 3 of them due to the type of plate material 2 ocean plates (basalt) converge both will go down into the mantle destroying rock subduction zone trenches and volcanoes these volcanic islands are called island arc example- Japan earthquakes

1 ocean plate (basalt) 1 continental plate (granite) converge subduction zone- ocean plate will go down into the mantle destroying rock trenches and volcanoes these volcanic mountains are called a volcanic arc example- Andes Mountains earthquakes

2 continental plates (granite) converge neither goes down into the mantle folded mountains example- Himalayas earthquakes

Transform Faults (strike-slip) 2 plates slide past each other horizontally no mountains are created earthquakes example- San Andreas fault
