Question

What happens to the plates and the mantle at plate boundaries?

Try to include the following terms in your response: plate, mantle, convergent boundary, divergent boundary.

Answer 1

At plate boundaries, different interactions occur depending on the type of boundary. Convergent boundaries involve subduction and can lead to mountain ranges and volcanic activity. Divergent boundaries involve the creation of new crust through magma rising up from the mantle. Transform boundaries usually result in earthquakes.

Step-by-step explanation:

At plate boundaries, the plates and the mantle can undergo different interactions depending on the type of boundary. In a convergent boundary, where plates are moving toward each other, one plate may be forced underneath the other in a process called subduction. This can lead to the formation of mountain ranges and volcanic activity. In a divergent boundary, where plates are moving away from each other, magma from the mantle can rise up to fill the gap and create new crust. This can result in the formation of mid-ocean ridges and volcanic activity. Transform boundaries, where plates slide past each other, usually result in earthquakes along the fault line.
