Volcanoes are really amazing. A phenomenon full of mystery that usually attracts the attention of the little ones. Volcano, by the way, comes from 'Vulcan', who was the God of fire according to Greek Mythology. You want to know more? We offer you a series of curiosities about this phenomenon that will help you answer some of your child's questions. Here are the most popular children's whys about volcanoes:

  1. How is a volcano formed? Perhaps your child thinks that the volcano is nothing more than a hollow mountain inside with fire waiting for the moment to go outside. In reality, volcanoes are formed from molten rock that is underground, in the deepest layers.
  2. How long does a volcano take to form? It is a very slow process, and it can take hundreds of years. For this reason, volcanoes sometimes surprise with a very powerful eruption.
  3. In which area of ​​the planet are there the most volcanoes? There is an area where more volcanoes are formed. It is the area of ​​Indonesia. In fact, the most powerful volcano in history erupted on Mount Tambora, on an Indonesian island, in 1815.
  4. Can a volcano be extinguished? Yes. Although the correct term is 'can be extinguished'. Just as the volcano is born, it can become extinct if it cools down over time. But be careful, the dormant volcanoes, which are those that are extinguished but can re-erupt, should not be confused with the extinct volcanoes, which are those that will never be active again.
  5. And how big can a volcano be? The largest volcano in the world is almost 4,000 meters high and is in Hawaii. It's called Mauna Loa. But it is not higher: the highest is Nevado Ojos del Salado and is between Argentina and Chile. It measures almost 7,000 meters.
  6. But ... is it that volcanoes grow and grow without stopping? Volcanoes grow, yes, like people. And they grow because lava and ash accumulates in their outer layers, so that their structure grows.
  7. And what is the gigantic crater with smoke coming from made of? That crater is called a caldera. It occurs when magma becomes trapped in an area and a bowl-shaped crater is created.
  8. What is lava made of? Lava is magma, which is made up of molten rock and volatile, solid compounds found on the Earth's surface. But in addition, along with these substances, there may also be gases and crystals in suspension. Of course, the temperature is very high. They can exceed 1000 degrees Celsius.
  9. Why does lava turn into stone when it cools? It's called a pumice stone, and it's so light that it could float on water. It is the only rock that can float! It is grayish and full of small holes. And yes, it is nothing but lava when it cools down.
  10. And why is the pumice stone full of holes? Those holes are made by hot gases on lava. When it cools down, the gas disappears and those characteristic little holes remain.
