Explanation:

Magma refers to molten rock which is stored in the earth’s crust from which igneous rocks are formed. It is a combination of minerals and small quantity of dissolved gases which include: water vapor, carbon dioxide and sulfur. Magma is of three basic types, which are: basaltic, andesitic, and rhyolitic and each of these three has different mineral composition. Magma is in its fluid state whenever there is high temperatures and pressure under earth’s crust.
