'Volcano Facts and Causes - Info about Volcanoes for Kids | Types of Volcano for Kids | Volcanos Kids Pop over to www.learningmole.com for more fabulous videos. In this educational video, kids will get to know all what they might think about when it comes to volcanoes and every single question they might have will be answered - if you have any question that is not answered here, please send us over and we will provide you with the right answer. At the beginning of the journey and the first question asked is, what is a volcano? Volcanoes are openings in the earth\'s surface. A volcano is a landform, that is usually a mountain, where molten rock erupts through the surface of the planet. How are these volcanoes formed? These volcanoes are formed when magma from the earth\'s upper mantle works its way to the surface. At this surface, it erupts to form lava flows and ash deposits. As the volcano continues to erupt, it will get bigger and bigger. Are there different types of volcanoes? Yes, actually there are four types of volcanoes. The first type is called the Cinder Cones which are circular or oval cones and they are made up of small fragments of lava. The second type is the Composite Volcanoes which are steep sided volcanoes and are made of many layers of volcanic rocks, they are usually made of high-viscosity lava, ash and rock debris. The third type is the Shield Volcanoes, these volcanoes are shaped like a bowl or shield in the middle with long gentle slopes made by basaltic lava flows. The fourth and last type if known as the Lava Volcanoes; lava domes are formed when erupting lava is too thick to flow and makes a steep-sided mound as the lava piles up. Since volcanoes are part of the earth and happen in it, it is important that kids know more about the earth and its layers. How many layers is the earth made of and what are they? There are three different layers that the earth is made of and they are the crust which is about 18 miles thick and this is the one we live on, the second layer is called mantle and this is about 1,800 miles thick and the third layer is called the core. What are the different stages of volcanoes? There are three main stages of volcanoes out there, these stages include the active, the dormant and the extinct. An active volcano is the one that has recently erupted and there is a possibility that it might erupt soon. A dormant volcano has not erupted in a long time but there is also a possibility for it to erupt soon. An extinct volcano is the one that erupted thousands of years ago and there is no possibility for it to erupt anytime soon. How do these volcanoes erupt? The earth\'s crust is made up of huge slabs called plates, these fit together like a jigsaw puzzle. Between the earth\'s crust and the mantle is the magma, which is made of rock and gases. When two plates collide, one section slides on top of the other, the one beneath is pushed down and magma is squeezed up between the two plates. Continuing with the different questions that kids might ask when it comes to volcanoes and understanding everything related to them, they might also ask about what will happen in an eruption? Actually eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. Volcanic eruptions have been known to knock down entire forests, and an erupting volcano can also trigger tsunamis (https://www.youtube.com/watch?v=q1mozwcqKBE), flash floods and earthquakes (https://www.youtube.com/watch?v=cu_PBjBIFKI). What is the difference between lava and magma? When the magma erupts through the earth\'s surface, it is called lava and this is the first difference. Magma is actually the liquid rock inside the volcano, while the lava is the liquid rock that flows outside the volcano. What is the Ring of Fire? Over half of the world\'s volcanoes arise in a belt around the pacific ocean called the Ring of Fire. How many volcanoes are there in the world? A good question to be asked because kids will be wondering! There are around 1,510 active volcanoes in the world! and some of them are even under the oceans. What is the largest active volcano? Mauna Loa in Hawaii, where famous coffee is actually grown in the rich volcanic soils! This active volcano in Hawaii is actually taller than Mount Everest, it is 13,677 feet above sea level. There are general information related to volcanoes which are interesting to know about, it starts with the origin of the word \"volcano\" itself which is believed to come from the name of the Roman God of Fire, Vulcan. The second interesting yet scary piece of information is about the 350 million people who actually live in the world within danger range of an active volcano!'
