New Zealand and the outback
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
