Learn how volcanoes form, how they erupt, and how they affect the world around them. See stunning images of volcanoes from around the world and discover the difference between explosive and effusive eruptions.
- Put simply, a volcano is an opening in the Earth’s surface. Usually found in a mountain, the opening allows gas, hot magma and ash to escape from beneath the Earth’s crust.
- The word “volcano” comes from the Roman name “Vulcan”. “But who was Vulcan?” you might ask. He was the Roman god of fire! Love animals? You’d love our magazine!
- Volcanoes are often found at meeting points of “tectonic plates”. These plates are pieces of the Earth’s surface that fit together just like a jigsaw puzzle.
- Volcanoes can also occur over “mantle plumes”. Ever heard of mantle plumes? They’re super-hot areas of rock inside the Earth! Did you know that we have a FREE downloadable Volcanoes of Ecuador primary resource?

If you go outside and touch the ground it will probably be quite cool. If it's a hot day then the ground may be a little warm from the sun, but it will quickly cool down again in the night. Underground, it's a different story. If you dig down far enough, you will break through the hard, cool, surface of the Earth and reach a much hotter and softer ...
The surface of the Earth is known as the crust. Just like the crust of an apple pie. Mmmm, apple pie. Er, anyway, the crust is broken into seventeen huge parts. These parts are called 'tectonic plates'. The tectonic plates float on top of a hot layer of softer rock. It's a bit like sheets of broken ice floating on top of a lake. But much, much hott...
The liquid rock is called magma when it is below the surface. Once it has emerged it is called lava. When the lava is escaping from the volcano, the volcano is said to be 'erupting'. Eruptions can be started by explosions caused by water or gas coming into contact with the liquid rock under the ground. Eruptions can be very powerful, with lava expl...
Before a volcano erupts there is often an explosion that throws volcanic ash into the air. Volcanic ash is made of small fragments of rock, glass and minerals. Sometimes it can be even more dangerous than the lava, as it is very hot and heavy. The ash settles around the volcano, and the lava then flows over it and solidifies. Every time a volcano e...
Volcanoes can either be active, dormant or extinct. However, because volcanoes can be around for millions of years, these definitions aren't awfully scientific. Active volcanoesare ones which are still likely to erupt, or have done so recently. By recently I mean in the last 10,000 years! That can be quite a short time when you're talking about roc...
The most obvious danger is the lava. It is so hot that it will burn anything it touches. In 1950, Lava from an erupting volcano was flowing towards the Hawaiian city of Hilo. The US Air Force had to drop bombs on the lava to divert the flow away from the city.
The explosions from a volcano are also very dangerous. In 1883, a volcano on the island of Krakatoa began to erupt. After some minor eruptions, the volcano exploded violently. Very violently, in fact. The explosions were heard over 5,000 miles away! The cloud of ash from the volcano darkened the sky all around the world, and made the whole north pa...
So there are the explosions. And the lava. But often the worst part of all is the ash. It's a bit like the ash from a bonfire in the garden. But there's much, much more of it, and it's much, much hotter. And it's made of rock, not wood. One of the most famous of all volcanoes is Vesuvius, in Italy. A long time ago, in AD79, it suddenly erupted. The...
A volcano is created when molten rock from deep below the groundescapes through the Earth's crust.The molten rock comes from 'magma chambers'; large underground pools of liquid rock.Volcanoes are named after the island of Vulcano, which itself was named after Vulcan, the Roman god of fire.The molten rock is called magma before it reaches the surface, and lavaonce it is out.Learn what volcanoes are, where they are found and how dangerous they can be. See pictures and examples of different types of volcanoes, lava and eruptions.

Aug 14, 2018 · Boom! A volcano is a mountain or hill with an opening. When a volcano erupts, magma is pushed up through the opening with great force. When magma reaches the Earth’s surface, it is called lava. Lava can be as hot as 2,200°F (1,204°C). Some volcanic eruptions are explosive. Lava shoots into the sky.
