A volcano is a mountain that has an opening to an inner magma chamber. As pressure builds, it will eventually erupt and can trigger other natural disasters and have large effects on the environment.
Volcanoes are able to produce landscapes over time, responsible for creating 80% of our planet’s surface. This means volcanoes are both vital to sustaining life, but also kill many living beings during their violent eruptions. Every volcano is different, varying in many sizes or types. Volcanoes also have large effects on the Earth’s landscape and biosphere. Withuot them, our entire planet would be forever changed.
The word “volcano” comes from the Roman name “Vulcan”.
Lava can reach 1,250° Celsius.
There are about 1,500 active volcanoes in the world.
The largest volcano on Earth is in Hawaii.
From sea level it is 4,169 metres high. However, under the sea it also goes down another 5,000 metres. This would make it higher than Mount Everest!
Since 1843, it has erupted 33 times.
Volcanoes often are located where tectonic plates meet.
Approximately 350 million people live within “danger range” of an active volcano.
Magma and lava are two different things!
Magma is the molten liquid inside a volcano. Once it leaves, it is known as lava.
Volcanoes can occur both underwater and on land.
The magma is stored in what's called a "magma camber" or "magma reservoir"
