What is a volcano simple definition?
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 called volcano?
A volcano is a vent or chimney which transfers molten rock (known as magma) from depth to the Earth’s surface through eruptions. Magma erupting from a volcano is called lava. Lava builds up around the vent and forms a cone.
What is the definition of 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 would you describe a volcano?
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.
What is the best meaning of 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.
What causes a volcano?
Most of the world’s volcanoes are found around the edges of tectonic plates, both on land and in the oceans. On land, volcanoes form when one tectonic plate moves under another. When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
What kind of volcano erupts without warning?
White Island is one of several volcanoes in New Zealand that can produce sudden explosive eruptions at any time. In this case, magma is shallow, and the heat and gases affect surface and ground water to form vigorous hydrothermal systems. In these, water is trapped in pores of rocks in a super-heated state.
How do you know when a volcano is not going to erupt anymore?
When there are no signs of an active magma chamber beneath the volcano (no unusual seismic activity, no volcanic gasses escaping etc.), and when there hasn’t been any activity for a long time span (at least 10,000 years).

What are the two definitions of the term volcano?
Strictly speaking, the term volcano means the vent from which magma and other substances erupt to the surface, but it can also refer to the landform created by the accumulation of solidified lava and volcanic debris near the vent.
What does the word volcano mean?
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. Origin: From vulcano, from Vulcanus the Roman god of fire and metalworking.
