Magma Versus Lava: How It Melts, Rises, and Evolves

2/4/2018· That''s because high pressure counteracts high temperature. Put another way, high pressure raises the melting point. Given that situation, there are three ways to create magma: raise the temperature over the melting point, or lower the melting point by reducing the pressure (a physical mechanism) or by adding a flux (a chemical mechanism).
