GEOLOGY

Detailed explanation-1: -Magma is a molten and semi-molten rock mixture found under the surface of the Earth. On the rare occasions when magma breaks the surface, as in a volcanic eruption, it is called lava.

Detailed explanation-2: -Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth’s surface.

Detailed explanation-3: -Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. When magma flows onto Earth’s surface, it is called lava.

Detailed explanation-4: -The models showed that two factors–the ability of water vapor to bubble out of the magma, and the ability of the crust to expand to accommodate chamber growth–are the key factors constraining the depth of magma chambers, which are generally found between six and 10 kilometers deep.

Detailed explanation-5: -Magma is typically located within the crust and in the upper mantle. Magma is liquid rock found within Earth. Magma is found within the chemical layers of Earth: the crust, and upper mantle because the processes that occur in these locations create the circumstances in which rock can melt.
