Molten rock that flows beneath the earth's surface and is made up of gases, liquids, and crystals. When magma reaches the surface, it is called lava. Marble. A type of metamorphic rock formed when limestone is pushed down into the earth and subjected to intense heat and pressure for a long period of time. Melting. The process that turns any rock into magma. Melting a rock requires extremely high temperatures, which only occur far beneath the earth's surface. Metamorphic Rock. One of the three main rock types, formed deep within the earth, where rock material is subjected to intense heat and pressure (squeezing).
Transfer of Heat. Magma can also be created when hot, liquid rock intrudes into Earthâs cold crust. As the liquid rock solidifies, it loses its heat to the surrounding crust. Much like hot fudge being poured over cold ice cream, this transfer of heat is able to melt the surrounding rock (the âice creamâ) into magma. Transfer of heat often happens at convergent boundaries, where tectonic plates are crashing together.
