Question 6
Global Science Final Exam.


The three types of plate boundaries are convergent, divergent and transform. Convergent plate boundaries occur when two or more tectonic plates or fragments of lithosphere move toward one another and collide. Divergent plates is the exact opposite of convergent plates, divergent plates occur when plate tectonics move away from one another. Transform plate boundaries occur when two plates slide past one another.

A geographic feature associated with a divergent boundary is mid Atlantic ridges and continental drifts. And example of a transform boundary would be the San Andreas Fault or the Alpine Fault, NZ. And an example of convergent plate tectonics coming together would be the India-Asia collision or the Himalayas.

Plate tectonics are a key component in the sea floor spreading. The sea floor is spreading due to divergent plate tectonics. Mid-ocean ridges, such as the mid-Atlantic ridge is a clear example of convergent plate tectonics. The moving of these plate tectonics is creating these natural phenomenons such as the mid-Atlantic ridge.
