3. Structure of a volcano A volcano constitutes a vent, a pipe, a crater, and a cone. The vent is an opening at the Earth's surface. The pipe is a passageway in the volcano in which the magma rises through to the surface during an eruption. The crater is a bowl-shaped depression at the top of the volcano where volcanic materials like, ash, and lava are released. Lava, ashes, and cinder form the cone. Layers of lava, alternate with layers of ash to build the steep sided cone higher and higher.

5. Why volcanoes are important? When a volcano erupts, it throws out a lot of ash. At short notice this ash can be very harmful to the environment, but ash contains many useful minerals, that will be converted to a very fertile soil. People use the rich soil for farming. Even after an eruption, people still return because of the fertile soil around the volcano.

6. Fun Fact The island of Hawaii was formed by a volcano erupting.
