GEOLOGY

Detailed explanation-1: -Magma is a molten and semi-molten rock mixture found under the surface of the Earth. This mixture is usually made up of four parts: a hot liquid base, called the melt; minerals crystallized by the melt; solid rocks incorporated into the melt from the surrounding confines; and dissolved gases.

Detailed explanation-2: -Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava.

Detailed explanation-3: -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-4: -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-5: -Is the Earth’s mantle made of liquid magma? The Earth’s mantle, on which the crust is lying on, is not made of liquid magma. It is not even made of magma. The Earth’s mantle is mostly made of solid rock.
