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: -Molten rock below the surface of the Earth that rises in volcanic vents is known as magma, but after it erupts from a volcano it is called lava.

Detailed explanation-4: -The first, magma, refers to any molten rock that is below Earth’s surface. Earth’s outer core is pure molten rock at a very high temperature. Magma is also found in the mantle in between the core and the crust. When magma comes to the surface through a volcano, however, it becomes known as lava.

Detailed explanation-5: -Extrusive Igneous Rocks: These are the rocks that form at erupting volcanoes and oozing fissures. The magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere.
