Question

When two plates that differ in _________ collide, volcanoes often form nearby.

Option 1: Thickness
Option 2: Density
Option 3: Temperature
Option 4: Speed

Answer 1

When two plates that differ in density collide, volcanoes often form nearby. Plates can slide parallel to each other or collide. Subduction of an oceanic plate beneath another can lead to volcanic activity due to the release of water.

Step-by-step explanation:

When two plates that differ in density collide, volcanoes often form nearby. As tectonic plates move, they can slide parallel to each other in opposite directions or collide. When two plates collide, one plate is often forced beneath another, in a process called subduction. If the subducting plate has an oceanic crust type, it can cause volcanic activity due to the release of water contained in hydrated minerals in the subducted plate.
