Tectonic Theory
Tectonic theory is that the earth is made up of different plates, all of the plates float on liquid mantle. Because the plates move on liquid mantle the plates move around the earth, but the pull of the mantle pushes the plates in multiple different directions. because of this we get different types of plate boundaries.

Because the plates move on liquid mantle the plates move around the earth, but the pull of the mantle pushes the plates in multiple different directions. because of this we get different types of plate boundaries.
The Plates
The different plates all move in different directions this creates 3 different types of plate boundaries.
The Divergent Plate Boundary
This is when the two plates that are touching are moving apart from each other. the convection currents pull the two plates apart from each other then the liquid mantle rises up to fill the gap between the two plates, creating new land. Although at the other end a destructive convergent boundary is being created.

The Destructive Convergent Plate Boundary
This is when the two plates are moving towards each other the lighter one (generally the oceanic crust) gets pushed underneath the continental crust/plate, into the subduction zone. In the subduction zone the oceanic crust melts. Once the crust melts it rises up and forms a volcano.

The Crumple and Buckle Convergent Plate Boundary
This is when there are two plates moving towards each other The two plates collide with such force that the two plates crust crumples up. This forms mountain ranges like the Himalayas or under water mountain ranges like the mid-Atlantic ridge.

The Transform Plate Boundary
This is when the two plates slide past each other they can go the same way or different ways. The two plates can also go at different speeds.

The Normal Fault Line
This is when the less stable plates drops below the more stable one.
This is when the less stable plates drops below the more stable one.
The Reverse Fault Line
the pressure compresses the two sides so that eventually one moves up and the other drops down.

The Strike-Slip Fault
This is when the two plates slide past each other, they go in the same direction.

The Hypocenter
The Hypocenter is where the earth quake starts, it is the point below ground where the plates of faults are moving.
The Epicenter
The Epicenter is the point at ground level in which the earth quake effects.
