Divergent Boundaries and Convergent Boundaries

Places where convergent boundaries show up are where tectonic plates crash or crunch together. Divergent Boundaries are places where plates move apart. Plates barely move they are slower than a snail, so collisions can last REALLY long. Convergent Boundaries make mountains and sometimes volcanoes. Mountains were mostly created not volcanoes. Mountains are created when one plate goes down and one plate goes up, soon the water will erode the land into a mountain. Divergent Boundaries always make volcanoes but no mountains. Volcanoes are created when the plates move back and magma goes up it soon makes a active volcanoes. Earthquakes are caused when plates smash together.

Mid-Ocean Ridge

I can bet that you think that the Himalayas are the longest mountain range ever. Well your WRONG, the Mid-Ocean Ridge is actually the longest mountain range ever, even though it is underwater. The Mid Ocean Ridge shows the boundary between two tectonic plates. You can go there and watch them..... But i suggest you bring some diving gear
