How volcanoes are formed and erupt? Magma rises from the hot spots and erupts as lava through cracks in the Earth’s surface forming volcanoes. As a plate moves slowly across a hot spot, a chain of volcanoes or volcanic islands can form.
What is a volcano how is it formed? A volcano mountain is formed by the surface eruption of magma from within the earth’s upper mantle. The magma that erupts to the surface forms a lava flow that deposits ash. As the volcano continues to erupt, a new layer of lava is added to the surface, accumulating to form a mountain.
How is a volcano formed short answer? Volcanoes occur when material significantly warmer than its surroundings is erupted onto the surface of a planet or moon from its interior. On Earth, the erupted material can be liquid rock (“lava” when it’s on the surface, “magma” when it’s underground), ash, cinders, and/or gas.
How are volcanoes formed essay? A volcano is a cone shaped hill or mountain which is built-up around an opening in the earth’s surface through which hot gases, rock fragments and lavas are ejected. Due to the accumulation of the solid fragments around the conduit a conical mass is built which increases in size to become a large volcanic mountain.
