How volcanoes are formed on Earth?
O Divergent plates cause mountains to separate, leaving room for magma to enter and erupt.
O Water just under the crust heats the magma, moves from the mantle to the bottom of the crust, until pressure increases and it erupts.
● Weathering and erosion carve out an opening at the tops of mountains, which allows magma in the ground to rise and cause eruptions.
O Hot magma in the mantle convects, slowly moving as heat circulates from the core to the surface, pulling or pushing the tectonic plates
