      Hi Rhiana,
      Volcanoes come in all shapes and sizes. Some are smal and flat, some are big and pointy.

      Yellowstone is one of the biggest explosive volcanoes on Earth. It is so big, that it wasn’t recognised as being a big volcanoes for many many years.

      The worlds largest volcano is Mauna Loa on Hawaii. Its taller than over 43 Big Bens stacked on top of each other. Thats tiny though compared to Olympus Mons on Mars – the solar systems biggest volcano. Olympus Mons is 3 times bigger than Mount Everest – thats over 221 Big Bens stacked on top of each other!
