What are three ways you can melt a rock to make magma?

In this regard, what are three ways you can melt a rock to make magma quizlet? Extrusive igneous rocks form by the freezing of lava above ground, in contact with air or water, after it erupts. Describe the three primary ways that magma is formed in the Earth. Decompression- pressure prevents melting but a decrease in pressure can trigger melting as long as the rock remains hot.

· Thus, diffusion during aqueous fluid-rock interactions may also explain NAM H 2 O contents that are too high to reflect residues of melting. These relatively short timescales at low temperatures suggest that the origin of water contents measured in peridotite NAMs requires additional constraints on sample petrogenesis, including petro-graphic ...

Melting Points of Rocks and Minerals

· Melting Points of Rocks Igneous rocks form through the crystallization of magma.There is a considerable range of melting temperatures for different compositions of magma. All the silicates are molten at about 1200°C (when a part of rock) and all are solid when cooled to about 600°C. Often the silicates are grouped as high, medium and low-melting point solids.
