Question

what are the 3 main types of tectonic plate boundaries

Answers

Answered by GPT 3.5
The three main types of tectonic plate boundaries are:

1. Convergent Boundaries: These occur when two plates collide with each other, resulting in the formation of mountains, trenches, and volcanic activity. There are three types of convergent boundaries: oceanic-continental, oceanic-oceanic, and continental-continental.

2. Divergent Boundaries: These occur when two plates move away from each other, leading to the formation of new crust. This process creates rift valleys on land and mid-ocean ridges under the ocean, where magma rises to the surface and solidifies.

3. Transform Boundaries: These occur when two plates slide past each other horizontally, resulting in earthquakes. Transform boundaries are characterized by a lack of volcanic activity and the formation of faults such as the San Andreas Fault in California.
