Huw James took a trek up Mount Etna and decided to show us what actually happens when a volcano erupts! With a little bit of help from Dr Suze Kundu and using a simple demonstration heating a glass beaker of wax, stone, sand and water we can see what happens when a volcano erupts. We can actually tell a lot about a volcano looking at the lava that comes out. If the lava is quite dense and thick we know it contains a lot of the compound silica. If it is less dense it has less silica and spreads out a lot more. Thick lava will generally erupt from one vent and follow one flow down the side of the volcano. Thinner lava, lava that is less dense, generally erupts from the surrounding magma chambers and flows in many different channels. Did you know that Mount Etna erupted recently? Check out this amazing video from BBC News! http://www.bbc.co.uk/news/world-europe-24980153 Have you found yourself half way up an active volcano and need to find north quickly? Well Check out Huw's vid on How to find North: http://www.youtube.com/watch?v=HalWPa6Ef5E&list=PLMrtJn-MOYmd9qywSe0JaCOed0t4CVV1l&index=3 Wonder why it's colder when you're high up a mountain?

Scientists believe they've discovered the largest volcano on Earth! But it's not the biggest one out there. Trace looks at the greatest volcanoes in our Solar System. Read More: Underwater volcano is Earth's biggest http://www.nature.com/news/underwater-volcano-is-earth-s-biggest-1.13680 "Geophysicists have discovered what they say is the largest single volcano on Earth, a 650-kilometre-wide beast the size of the British Isles lurking beneath the waters of the northwest Pacific Ocean." The Tallest Mountains in the Solar System http://blogs.smithsonianmag.com/science/2012/01/the-tallest-mountains-in-the-solar-system/ "If asked to name the tallest mountain on Earth, most people would answer Mount Everest. They'd be wrong--Everest is the highest peak on the planet, but mountains are measured from their base to their peak, and Everest's base sits far above sea level on the Tibetan Plateau. And when you start looking at the tallest (known) mountains in the solar system, Mount Everest, at only 2.3 to 2.9 miles tall (depending on where you decide the mountain's base is located), doesn't even make the list:" Io: Overview http://solarsystem.nasa.gov/planets/profile.cfm?Object=Jup_Io "Looking like a giant pizza covered with melted cheese and splotches of tomato and ripe olives, Io is the most volcanically active body in the solar system. Volcanic plumes rise 300 km (190 miles) above the surface, with material spewing out at nearly half the required escape velocity." Deep In The Pacific, Scientists Discover Biggest Volcano On Earth http://www.npr.org/blogs/thetwo-way/2013/09/06/219690370/deep-in-the-pacific-scientists-discover-biggest-volcano-on-earth "The world's largest volcano has until now been lurking undiscovered in the depths of the Pacific Ocean, according to a team of scientists who identified the massive object and reported their findings in the latest issue of Nature Geoscience." OLYMPUS MONS http://marsprogram.jpl.nasa.gov/gallery/atlas/olympus-mons.html "The largest of the volcanoes in the Tharsis Montesregion, as well as all known volcanoes in the solar system, is Olympus Mons." Olympus Mons: Giant Mountain of Mars http://www.space.com/20133-olympus-mons-giant-mountain-of-mars.html "Olympus Mons is the largest volcano in the solar system. The massive Martian mountain towers high above the surrounding plains of the red planet, and may be biding its time until the next eruption." Plate tectonics confirmed on Mars http://io9.com/5933638/plate-tectonics-confirmed-on-mars "After nearly forty years of research, scientists have finally proven that plate tectonics exist on Mars. A recently published paper by An Yin in the journal Lithosophere reveals that the origin of Valles Marineris on Mars — the longest trough system in the solar system — was formed by rifting, strike-slip faulting, and subsurface mass removal. Yin's research now shows that Earth's surface is not the only one in the solar system subject to the forces of plate tectonics."
