Question

During the process of burial, parts of Earth’s crust descend into the mantle. This is caused by the movement of tectonic plates. Which type of plate boundary is responsible for plates coming together and one plate moving under the other?

Answer 1

The type of plate boundary responsible for plates coming together, where one plate moves under the other, is called a **convergent boundary**. At convergent boundaries, two tectonic plates collide, and one plate is typically forced down into the mantle beneath the other in a process known as subduction. This can lead to the formation of mountain ranges, earthquakes, and volcanic activity.
