briefly about Dormant volcano
Answers
Answer:
A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.

A volcano is an opening in the Earth’s crust that allows magma, ash and gasses to erupt from below the surface. It is made up of a magma chamber, a vent, a crater and a cone shaped mountain made of layers of ash and lava.
Magma chamber → Magma from the Earth’s mantle collects in a large underground pool. The magma in a magma chamber is under great pressure trying to force its way upward to the surface.
Vent → The magma forces its way up through the vent which is like a chimney for the volcano. There is the main vent but there can also be secondary vents on the side or flank of the volcano. These secondary vents produce secondary cones on the flank of the volcano.
Crater → The crater or caldera is the bowl shaped feature on top of the volcano that the magma from the vent erupts form.
Cone shaped mountain → The majority of volcanoes are cone shaped mountains. They are formed of alternating layers of lava and ash from multiple eruptions. As the volcano erupts a layer of lava forms, the ash cloud formed during the eruption later cools and falls, this is known as pyroclastic flow. This forms a layer of ash on top of the lava. This process is repeated each time the volcano erupts.
