Asthenosphere

3 ways minerals are formed

Igneous rocks form from molten material called magma. Sedimentary rocks form from sediments deposited out of water or the air. Metamorphic rocks form from the alteration of other rocks through temperature and pressure induced changes in the minerals.

Most abundant gas in atmosphere

Nitrogen

There are two known processes by which magma ceases to exist: by volcanic eruption, or by crystallization within the crust or mantle to form a pluton. In both cases the bulk of the magma eventually cools and forms igneous rocks.

Magma Formation Process

The explanation for why specific minerals tend tooccur with each other and not with other minerals in igneous rock. Mineral occurrence in igneousrocks is related to the actual temperature at which they crystallize (not therate).
