Yeah, its not really my field of expertise but there are some pretty interesting rocks under the sea. I think the most interesting parts are really when the rocks break apart and we get a crevasses, or vent into the earths interior. There are loads of these underwater volcanoes which shoot out really hot water into the deep ocean.
Hi kyle,
Rocks under the sea are really important. Firstly, the sea is where most sedimentary rocks are formed, as layers of sediment accumulate and are gradually turned into rocks. Oil is found only in sedimentary rocks, so the majority (but not all) of oil finds are offshore. So rocks under the sea are really important economically – think of all those oil rigs out in the North Sea, which is a major oil field.
On top of the rocks under the sea are huge thick layers of muddy sediments that contain the fossilised remains of plankton called foraminifera We can do chemical tests on their shells and from this work out the temperature of the sea when these foraminifera died and so we know what the climate was like in the past. This is really important for my work, and while not yet rocks, these sediments are also really important!
