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 an 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. When magma flows or erupts onto Earth’s surface, it is called lava.

Detailed explanation-3: -When magma reaches Earth’s surface and erupts from a volcano, it becomes lava. This material is available primarily for archival purposes.

Detailed explanation-4: -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-5: -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.
