sinking water

http://aquarius.nasa.gov/pdfs/density_SWmix_sink.pdf

this is something like a power point but isnt one. it talks about the fatthat the colder/ more saltier the ocean gets the more the water will sink

it is credilbe because it is by nasa and is by the government.

http://en.wikipedia.org/wiki/Thermohaline_circulation

this is by wikipedia but it has the sources of information that seem more credible

the source says that since the earth is heating up, the oceans start to sink because the water is becoming less dense causing it to sink.

there are many sources that look credible, even though there is no specific author.

i do belive this source because i has so many sources that look credible.

http://www.ncdc.noaa.gov/paleo/ctl/thc.html

this source breifly explains that since the earth is melting the ice in the poles causing the water to become more dense and sink in the ocean and resurface in another part of the world with even more dense water.

this website is credible because it is sponsered by the government.

i believe that this fact is true
