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.
Volcanic activity occurs at two types of plate boundaries: mid-ocean ridges and subduction zones. At mid-ocean ridges, basaltic eruptions produce new sea-floor crust. These underwater eruptions don't produce big mountainous volcanoes, which is why they are often overlooked as the most volcanically active features on Earth.
