When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperature and pressure cause the rock to melt and become liquid rock or magma. When a large body of magma has formed, it rises thorugh the denser rock layers toward Earth's surface
Lava (magma that has erupted onto the Earth's surface) is visually mesmerizing – as the molten rock flows downhill, lava exposed to the air cools to a deep black color, while the molten rock beneath glows bright orange.This magma can push through holes or cracks in the crust, causing a volcanic eruption.
There are many ways in which you can help conserve nonrenewable resources. You <span><span>could conserve nonrenewable resources by not using them. Hope it Helps
