GEOLOGY

Detailed explanation-1: -Eventually, some of the magma pushes through vents and fissures to the Earth’s surface. Magma that has erupted is called lava.

Detailed explanation-2: -When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals. It also contains small amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur. The high temperatures and pressure under Earth’s crust keep magma in its fluid state.

Detailed explanation-3: -/ˈlɑː.və/ hot liquid rock that comes out of the earth through a volcano, or the solid rock formed when it cools: molten lava.

Detailed explanation-4: -Main Vent: A volcano’s main vent is the weak point in the Earth’s crust where hot magma has been able to rise from the magma chamber and reach the surface.
