Introduction:
A volcano occurs when hot substances (solids, liquids, and gases) from inside the earth are pushed out through the earth’s crust. This happens because the interior of the earth is very hot, and these substances escape through cracks or openings on the surface.
- Volcanoes erupt in the sea as they do on land. The same substances that come out during the eruption of a volcano on the land are ejected during the eruption of a volcano in the sea.
- Some islands are created due to the eruption of volcanoes in the sea. It is not possible to prevent the eruption of a volcano, to stop it after it erupts, or to control it.
- However, by means of science and technology, it is possible to predict an eruption and to take immediate steps for disaster management.
Volcano
Causes and Effects
Causes:
- Heat and pressure inside the earth push hot substances toward the surface.
- The movement of molten rocks and gases from beneath the earth’s crust causes eruptions.
Effects:
- Lava and ash collect on the surface, forming mountains or hills.
- Ash and gases pollute the atmosphere.
- Rain often follows a volcanic eruption.
- Temperature rises due to hot gases.
- Forests and settlements can get buried under hot mud.
- Volcanic eruptions in the sea can create new islands.
