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.
The greatest number of the Earth's volcanoes occur on the ocean floor. ROV Jason gets a close view of magma explosions and lava flows on West Mata volcano. Volcanic eruptions occur only in certain places and do not occur randomly.This is because the Earthâs crust is broken into a series of slabs known as tectonic plates. These plates are rigid, but they âfloatâ on a hotter, softer layer in the Earth's interior.lthough most of the active volcanoes we see on land occur where plates collide, the greatest number of the Earth's volcanoes are hidden from view, occurring on the ocean floor along spreading ridges.
