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.
Divergent plate boundaries usually occur deep in the oceans. The mid-oceanic ridges are an example of this type of volcanic action. Occasionally, as is the case with Iceland, oceanic ridges rise above the surface of the ocean. Contrarily, convergent plate movement causes more visible volcanic action. Famous volcanoes, such as Vesuvius or Mount St. Helens, were caused by converging tectonic plates. In a process known as subduction, an oceanic plate collides with, and slides under, a continental plate.
