explain the type of volcanoes on the basis of periodicity of eruption with example.
Answers
Answer:
On the basis of periodicity of eruption, volcanoes are classified into three types:
(i) active volcanoes,
(ii) dormant volcanoes
(iii) extinct volcanoes. (i) Active Volcanoes: ... The Stromboli volcano emits so much fire and incandescent gases that it is known as 'the Light House of the Mediterranean Sea'.
A volcano is a land-form, a mountain, where molten rocks erupt through the surface of the planet. The volcano mountain opens downwards to a pool of molten rocks below the surface of the earth.
A volcano is a land-form, a mountain, where molten rocks erupt through the surface of the planet. The volcano mountain opens downwards to a pool of molten rocks below the surface of the earth.When the pressure builds up in the earth’s crust, eruptions occur. Gasses and rock shoots up through the opening and spill over or fill the air with lava fragments. The volcano eruption can cause lateral blasts, hot ash and lava flow, mud-slides, and more.
Categories of volcanoes:
Volcano are categorised into three main categories:
- Active
- Dormant
- Extinct
=> An active volcano is one which is recently erupted and there is a possibility that it may erupt soon.
=> A dormant volcano is one that has not erupted in a long time but there is a possibility it can erupt in the future.
=> An extinct volcano is one which has erupted thousands of years ago and there’s no possibility of an eruption.
