Geology 101 Origin of Magma From our discussions of the structure
... A common answer that people give is that increased temperature will cause a rock to melt. Although this is true, there are two other factors that have an important affect in melting: the pressure on the rock and the amount of water present. In general, thermal energy causes the atoms to move more ra ...
