GEOLOGY

Detailed explanation-1: -A volcano is defined as an opening in the Earth’s crust through which lava, ash, and gases erupt. The term also includes the cone-shaped landform built by repeated eruptions over time.

Detailed explanation-2: -Eventually, some of the magma pushes through vents and fissures to the Earth’s surface. Magma that has erupted is called lava.

Detailed explanation-3: -Magma-Molten rock beneath Earth’s surface capable of intrusion and extrusion. Vent-The opening or place at Earth’s surface through which magma, rock fragments, and/or volcanic gases are emitted. Volcanic edifice-A mountain or cone that is the main portion of a volcano.

Detailed explanation-4: -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. Like solid rock, magma is a mixture of minerals.

Detailed explanation-5: -Volcanic mountains are formed due to volcanic activity. The molten lava, after cooling down, deposits around the volcano continuously to form a mountain.
