Describe each plate boundary - transform, convergent, divergent. How do the plates move at each of these, what happens, and what features form (i. e. - trench, volcanic island, volcano on continent, mountain range, earthquake, rift valley, subduction).

Transform: The plates slide past each other, one going forwards, the other going back, kind of grinding each other. A Transform Boundary is also a fault, so it causes Earthquakes mostly.

Convergent: When two plates collide with each other. They form subduction mostly and trenches. They can also create volcanoes or volcanic islands.

Divergent: When two boundaries move away from each other. They form rift valleys, mountain ranges
