GEOLOGY

Detailed explanation-1: -A volcano is a feature in Earth’s crust where molten rock is squeezed out onto the Earth’s surface. This molten rock is called magma when it is beneath the surface and lava when it erupts, or flows out, from a volcano. Along with lava, volcanoes also release gases, ash, and solid rock.

Detailed explanation-2: -Magma is molten rock deep underground. Much of Earth’s mantle is made of magma. That magma can rise up through Earth’s crust and erupt out of volcanoes. Molten rock that has reached Earth’s surface is called lava.

Detailed explanation-3: -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-4: -When magma reaches Earth’s surface and erupts from a volcano, it becomes lava.

Detailed explanation-5: -A volcano is an opening in a planet or moon’s crust through which molten rock and gases trapped under the surface erupt, often forming a hill or mountain.
