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.
Volcanoes occur inland on the continental plates due to the subduction of an oceanic plate, or at weak points in the oceanic plates where magma is being heated from below. They can occur anywhere there is liquid rock (magma) welling up into spaces in the rocks above them.
