GEOLOGY

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 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, molten or partially molten rock from which igneous rocks form. It usually consists of silicate liquid, although carbonate and sulfide melts occur as well. Magma migrates either at depth or to Earth’s surface and is ejected as lava.

Detailed explanation-4: -If this molten rock reaches the surface and continues to flow as a liquid, it is called lava. Magmas vary in their chemical composition, which gives them and their volcanoes different properties.

Detailed explanation-5: -Molten rock that is inside the surface of the earth is known as Magma.
