GEOLOGY

Detailed explanation-1: -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-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: -Magma is a molten and semi-molten rock mixture found under the surface of the Earth. On the rare occasions when magma breaks the surface, as in a volcanic eruption, it is called lava.

Detailed explanation-4: -Extrusive Igneous Rocks: Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth’s surface. These are the rocks that form at erupting volcanoes and oozing fissures.

Detailed explanation-5: -Mantle. Underneath the Earth’s crust lies a thick layer of very hot rock. Most of the mantle is very solid-like, but there are areas that are more liquid-like which can move around more quickly. Mantle ›
