What is volcano Wikipedia?
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
What is volcano short paragraph?
A volcano is a mountain that has lava (hot, liquid rock) coming out from a magma chamber under the ground, or did have in the past. Volcanoes are formed by the movement of tectonic plates.

Top 10 Facts About Volcanoes
- Volcanoes are openings of the Earth’s surface.
- The word volcano comes from the word ‘vulcan’.
- Volcanoes can be active, dormant or extinct.
- The liquid inside the volcano is called magma.
- Lava is the liquid that is expelled from the volcano.
- Lava is very, very hot!
What are three facts about volcanoes?
More than 80% of the earth’s surface is volcanic in origin. The sea floor and some mountains were formed by countless volcanic eruptions. Gaseous emissions from volcano formed the earth’s atmosphere. There are more than 500 active volcanoes in the world.
What causes volcanoes?
Volcanoes occur when material significantly warmer than its surroundings is erupted onto the surface of a planet or moon from its interior. On Earth, the erupted material can be liquid rock (“lava” when it’s on the surface, “magma” when it’s underground), ash, cinders, and/or gas.
What are 3 good things about volcanoes?
6 ways volcanoes benefit Earth, our environment
- Atmospheric cooling.
- Land formation.
- Water production.
- Fertile land.
- Geothermal energy.
- Raw materials.
What are the 3 types of volcanoes?
The Three Classic Types of Volcanoes
- Cinder Cone Volcanoes.
- Composite Volcanoes (Stratovolcanoes)
- Shield Volcanoes.
Why are volcanoes called volcanoes?
The name volcano comes from Vulcan, the Roman god of fire! A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth’s surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope.
What are types of volcanoes?
Strictly speaking there are two broad types of volcano, a stratovolcano and a shield volcano, although there are lots of different volcanic features that can form from erupted magma (such as cinder cones or lava domes) as well processes that shape volcanoes.
What is a volcano for kids?
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments.
Why do we need volcanoes?
Volcanic materials ultimately break down and weather to form some of the most fertile soils on Earth, cultivation of which has produced abundant food and fostered civilizations. The internal heat associated with young volcanic systems has been harnessed to produce geothermal energy.
What is a volcano?
A volcano is a mountain with a hole where lava (hot, liquid rock) comes from a magma chamber under the ground. Most volcanoes have a volcanic crater at the top.
Where are volcanoes found?
Volcanoes are often found where tectonic plates are moving apart or coming together. Volcanoes can also form where there is stretching and thinning of the crust’s plates, e.g., in the East African Rift.
How are volcanoes classified in the United States?
The United States Geological Survey (USGS) has adopted a common system nationwide for characterizing the level of unrest and eruptive activity at volcanoes. The new volcano alert-level system classifies volcanoes now as being in a normal, advisory, watch or warning stage. Additionally, colors are used to denote the amount of ash produced.
