GEOLOGY

Detailed explanation-1: -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-2: -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-3: -When magma reaches Earth’s surface and erupts from a volcano, it becomes lava. When magma reaches Earth’s surface and erupts from a volcano, it becomes lava.

Detailed explanation-4: -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. Magma is made of molten rock, crystals, and dissolved gas-imagine an unopened bottle of soda with grains of sand inside.

Detailed explanation-5: -Lava (which as you undoubtedly know, is partially molten rock erupted by volcanoes) typically comes from the mantle-the Earth’s middle layer, sandwiched between the crust and the core. Once it reaches the surface, lava quickly cools down and solidifies completely, creating new land.
