👉 Subduction is a process in which two tectonic plates move closer to each other, causing significant changes in their position and shape. This can occur due to friction between the plates or through the movement of magma beneath them. The primary cause of subduction is the loss of heat from the surface of the Earth as it cools down. The process starts with a magma chamber forming where molten rock rises up from the Earth's crust, reaching temperatures that are far higher than what would be required
