Transform Boundaries and Seismic Activity

The video explains the three main types of plate boundaries: transform, divergent, and convergent. Transform boundaries are unique as they do not create or destroy crust, unlike the other two types. They are characterized by significant seismic activity and dispersed volcanoes. The San Andreas Fault is a notable example of a transform boundary, where two plates slide past each other, causing numerous earthquakes. Despite lacking dramatic features, transform boundaries demonstrate the power of tectonic movements, evident in the shifting of landforms over time.

What are the three main types of plate boundaries?

• Transform, Divergent, and Convergent

• Transform, Convergent, and Parallel

• Divergent, Convergent, and Parallel

• Transform, Divergent, and Parallel

Which feature is NOT commonly observed at plate boundaries?
