= = There are three different types of boundries there is convergent,divergent and transform.

Convergent boundries are when the plates move into each other.Also whenn the crust crumples and turns into a mountain.About 55 million years ago Asia and India crashed and slowly making the Hymalaya.They can also form where a plate of ocean divides.The earths crust is a unchanging that means that the crust is destroyed at the same rate that it is being created. transform boundries are when plates move sideways in relation to each other. Transform boundries grind past each other along what is called strike-slip faults these do not make oceans or mountains but they are what cause earthquakes.

DIvergent boundries are when the plates move apart from each other.When magma rises from the earths mantle it rises towards the surface and pushes apart two or more plates.mountains and volcanoes rise along the seam.That prossess renews the ocean floor.A single mid-ocean range system conects the worlds ocean.Making the ridge the longest mountain range in the world "moving and shaking." //science.nationalgeographic.com/science/earth/the-dynamic-earth/plate-tectonics-article//.
