GEOLOGY

Detailed explanation-1: -Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption.

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: -batholith, large body of igneous rock formed beneath the Earth’s surface by the intrusion and solidification of magma.

Detailed explanation-4: -Answer and Explanation: Magma, the melted rock below the surface of the earth, only exists in the crust layer of the Earth. This may be surprising because the mantle and the core are much hotter layers.
