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: -Complete answer: Igneous rock or magmatic rock is made up of molten magma. It is one of the three main rock types; sedimentary and metamorphic.

Detailed explanation-4: -A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards.

Detailed explanation-5: -Magma is an extremely hot liquid and semi-liquid rock located under Earth’s surface.
