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: -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: -Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.

Detailed explanation-5: -Magma comes from an Italian word that means a thick, pasty substance, which is how molten rock behaves within the Earth. Lava, another Italian word, means to slide, which is what molten rock does once it reaches the surface.
