World's biggest insect is so huge it eats carrots. Adventurer Mark Moffett has found the world's biggest insect - which is so huge it can eat carrots. Former park ranger Mark, 53, discovered the giant weta up a tree and his real life Bug's Bunny has now been declared the largest ever found.
The majority of the worldâs volcanoes are found deep underwater and now scientists have been able to record one of these eruptions as it happens to discover the sound it makes. The bubbling lava erupting from the volcanic vent Hades (above) produced a distinctive acoustic signature.
Many volcanoes occur near boundaries where two oceanic plates collide. Through subduction, the older, denser plate sinks beneath a deep-ocean trench into the mantle. Some of the rock above the subducting plate melts and forms magma. Because the magma is less dense than the surrounding rock, it rises toward the surface.
