What will happen to a rock if the temperature rises above the melting point of all its component minerals and conditions are necessary for rocks to melt?
Rock melts when the temperature of the rock increases to above the melting point of minerals in the rock. Rock melts when excess pressure is removed from rock that is close to melting. Rock may melt when fluids, such as water, are added. The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius to melt a rock, turning it into a substance is magma.
