The
continental plates or lithospheric plates are also called tectonic plates and are like a giant jigsaw. Continuously moving around they
push each other at a speed of 2 to 20 cm each year. When the plates move apart, lava streams out of the break making new ocean or continental
crust. Sometimes the plates grind together and one of the plates slowly sides under the other plate to form a deep ocean trench. The opposite of this is when the plates collide and mountains are formed, but one plate still slides under the other. This is called subduction.
