Plate Tectonics
 

Transform Boundaries

In plate tectonics there are three types of boundaries; divergent boundaries, convergent boundaries and transform boundaries. We have already discussed the first two types of boundaries, the third type of tectonic plate boundaries is transform boundaries.

What are transform boundaries?

With transform boundaries, when tectonic plates come near each other horizontally, the neight colliede nor pull apart but they slide past each other forming large transform faults or fracture zones. No new earth crust is formed and no existing crust is lost in transform boundaries. Many earthquakes occur along faults created by transform tectonic boundaries.

Where to find transform boundaries?

Most of the Earth's transform boundaries of tectonic plates are on the ocean floor along the edges of the mid ocean ridges. There are a few transform boundaries on land.

Examples of transform boundaries of tectonic plates

The most famous of the transform boundaries is the San Andreas Fault zone in Southern California where the Pacific Plate and the North American Plate slowly grind past each other.
