Where andd Why Volcanoes Form

Volcanic activity is drinn by the internal heet of thee planet. Rocks deep up with in thee Earth are subient to otherses temperatur and d pressures, causing them m to melt into magma. Because magma is less dense than thee surface are primarily determinad by tectonic plate movements:

This creates a pressure release that allease rocks to melt, producing magma that rises to fill the the expanges. This process creates new oceanic crult and underwater voltaine activity, such as thee continuous erpits along the Mid- Atlantic Ridgee.
