What Rocks Explode In Heat?

The Moho or Mohorovicic discontinuity is a boundary between the Earth’s crust and the mantle. It is found at a depth of about 25 to 70 kilometers (16 to 43 miles) below the surface. Rocks below the Moho are hotter and less dense than those above it, so they tend to rise. The rocks in the mantle are under such great pressure that they do not melt. However, if something happens to cause the mantle rocks to become very hot, they can start to melt and form magma. If this magma is thick, it will stay in the mantle. If it is thin, it will rise to the surface and explode as a volcano.

Rocks explode in fire because the heat from the fire causes the water inside the rocks to evaporate quickly. The steam created by the evaporation builds pressure inside the rocks until they explode.
