Detailed explanation-1: -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-2: -Magma. 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-3: -Magma is a mixture of molten and semi-molten rock found beneath the surface of the Earth.
Detailed explanation-4: -The molten rock that is present beneath the surface of the earth is termed as Magma. The molten liquid that gets erupted out of the surface of the Earth is termed as lava.
Detailed explanation-5: -Computer models show why eruptive magma chambers tend to reside between six and 10 kilometers underground. A new study reveals why the magma chambers that feed recurrent and often explosive volcanic eruptions tend to reside in a very narrow depth range within the Earth’s crust.
