What is volcano in short answer?

A volcano is an opening in the earth’s crust through which lava, volcanic ash, and gases escape. Beneath a volcano, liquid magma containing dissolved gases rises through cracks in the Earth’s crust.

What is the best definition of a volcano?

The definition of a volcano is a rupture in the Earth’s crust where molten lava, hot ash, and gases from below the Earth’s crust escape into the air. This then causes magma to rise up, and this creates a volcano. The volcanoes that form by this method are usually the most dangerous and the most volatile ones.

Can you describe the volcano?

Volcano. A volcano is a hole in Earth’s surface through which magma (called lava when it reaches Earth’s surface), hot gases, ash, and rock fragments escape from deep inside the planet. The word volcano also is used to describe the cone of erupted material (lava and ash) that builds up around the opening.

What is a volcano Class 7?

A volcano is a vent from which a combination of melted rock, solid rock debris and gas erupts. It has a reservoir of molten material below the surface (magma chamber) called magma, and when this magma rises to the surface, it is called lava.

What is a volcano kids explanation?

A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.

What is a volcano Class 5?

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. Volcano eruptions have been known to knock down entire forests.

What is a volcano Kid definition?

What is a volcano in geography?

A volcano is defined as an opening in the Earth’s crust through which lava, ash, and gases erupt. The term also includes the cone-shaped landform built by repeated eruptions over time. Teach your students about volcanoes with this collection of engaging material.

How do you explain a volcano to a child?

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. Hot ash and gases are thrown into the air.

Why does a volcano occur?

Volcanoes erupt when molten rock called magma rises to the surface. As the magma rises, bubbles of gas form inside it. Runny magma erupts through openings or vents in the earth’s crust before flowing onto its surface as lava. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises.

What is a volcano for Class 9?

Answer: Volcanoes are the vents in the earth’s crust erupting hot magma from the interior core motivated by endogenic forces.

What are 5 facts about volcanoes?

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 causes a volcano to form and then erupt?

To conclude, volcanoes are mainly formed in subduction zones or magmatic hotspots. And the volcanic eruptions are caused by the upthrust of magma, the pressure created by gases, and the influx of new magma in existing magma chambers. [1] “What Causes a Volcano to Erupt, and How Do Scientists Predict Eruptions?”

What does volcano stand for?

volcano(Noun) A vent or fissure on the surface of a planet (usually in a mountainous form) with a magma chamber attached to the mantle of a planet or moon, periodically erupting forth lava and volcanic gases onto the surface.

What are the advantages of a volcano?

Volcanic eruptions also bring forth precious gems, such as opals. Pumice stone , which is used in construction and as an excess-skin remover, also is created in volcanic eruptions.Volcanoes are also a large source of geothermal energy.
