Plate tectonics is the theory that Earth's outer shell is divided into 35 plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle.
1 of 5
Collision Plate Boundary
At this plate boundary, two continental plates move towards one another. Both are of equal strength therefore none are destroyed. Instead they buckle and fold mountains are formed.
2 of 5
Conservative Plate Boundary
Here two plates are sliding past one another. Material is not destroyed or created, instead there is friction. When this friction is released, an earthquake occurs.
3 of 5
Destructive Plate Boundary
This boundary is found where two plates are moving towards one another and oceanic plate material is being destroyed. As the continental crust is forced above the oceanic crust subduction takes place. This boundary is associated with earthquakes.
4 of 5
Constructive Plate Boundary
At this boundary, you will find new material rising to the surface - which forces plates apart. New land is created which is often underwater volcanoes.
