GEOLOGY

Detailed explanation-1: –It is a conical-shaped landform that is built by repeated eruptions.-Volcanoes are different than other mountains they are not formed by uplift and erosion.-A volcano is built around a vent that connects with reservoirs of molten rock.-It is built by the slow accumulation of erupted lava.

Detailed explanation-2: -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-3: -A volcano is a landform, a mountain, where molten rocks erupt through the surface of the planet. The volcano mountain opens downwards to a pool of molten rocks underneath the surface of the earth. Pressure builds up in the earth’s crust and this is the reason why eruptions occur.

Detailed explanation-4: -A volcanic eruption is when lava and gas are released from a volcano-sometimes explosively. The most dangerous type of eruption is called a ‘glowing avalanche’ which is when freshly erupted magma flows down the sides of a volcano. They can travel quickly and reach temperatures of up to 1, 200 degrees Fahrenheit.

Detailed explanation-5: -An active volcano is one that is erupting or has erupted recently. The International Association of Volcanology (IAVCEI) defines a potentially active volcano as one that has erupted during the past 10.000 years.
