3 Types of boundries
1. Divergent-magma rises and pushes plates apart. 2. Convergent-A plate collides with or dives under another. 3. Transforms-two plates grind against each other.

Convergent Boundries- Plates serving landmasses collide, and crust crumbles plus hockles into mountain ranges like india and asia crashed about 55 million years ago but slowly rising to the himalaya. Is the highest mountain system on earth then the continental plates melt then rise and that is what causes the volcanoes to eruped because of the oceanic plates.

Divergent Boundries- In the oceans magma from deep mantles and rises to the surface. The mountains and volcanoes rise along the seam. Single Mid-ocean ridge system connects the worlds oceans which means the ridge is the longest mountain range in the world it makes the new crust become wider its also makes shallow earthquakes to europed and it moves along the oceans mid-ocean ridge system.

Transform-San andreas fault in california transform boundry,two plates who grind with each other along called strike--slip faults. These boundries produce spectacular mountains or oceans the haulting motion often triggers large earthquakes,, such as the 1906 that devestated sanfrancisco and destroyed everything in its path just from the fault. And it all got caused by the plates and the melting and the cooling and stuff and the just went over top of each other and just caused a devestating earthquake and how the volcanoes europe "Dynamic Earth ." //National Geographic//.
