  At the bottom of the ocean at what we can ‘oceanic plates’. These a a specific type of tectonic plate, the top part of which is made up of types of rock called basalts and gabbros. They’re often covered by a layer of sediment, deposited from the sea (along with all sorts of other things – dead whales, sunken ships, etc).

  In addition to what Tim said, we also find organisms that are adapted to living in deep water – there is little/no light, and the pressure of all that water means that far fewer animals are able to survive. That means we find some really unique and interesting animals down there too!

  An awful lot of mud, been there seen it. Surface is better, lots of life
