What is a volcano?

Hint: Volcanoes are natural phenomena of the earth where a mountain opens downward to a pool of molten rock between the surface of the earth. And there are three types of volcanoes that are spatter cons, composite volcanoes and shield volcanoes.

Complete step by step answer:
Volcanoes are defined as the openings or vents where the lava, small rocks and the steam erupt on the Earth’s surface. Many of the mounts are formed by folding, faulting, uplifting and erosion of the Earth’s crust. Volcanic terrain is built by the slow accumulation of the erupted lava. The vent may be visible as a small bowl shaped depression at the summit of a cone shaped mountain. Hence through a series of cracks within and beneath the volcano. The vent is connected to one or more linked storage areas of molten or partially molten rock. And due to this connection to fresh magma allows the volcano to erupt over and over again in that same location. The volcano grows ever larger until and unless it is no longer stable. The pieces of the volcano collapse as rock falls or as landslides.

Note: There are so many side effects due to this erosion. It spews hot lava and releases dangerous gases, ash lava and rocks which are very destructive elements for our earth. Many people also died from these volcanic blasts. Remember that this eruption can result in additional threats to our environment such as floods, wildfires, mudslides, crop damages etc.
