Global Warming Today and the Worlds Oceans

The worlds oceans are shown below in order of size (descending order)

Pacific Ocean
Atlantic Ocean
Indian Ocean
Southern Ocean
Arctic Ocean

These five oceans together complete one connecting body of sea water, which is referred to as the world ocean, although these bodies of water are seen as separate oceans from each other.

The Pacific and Atlantic oceans can also be divided again by the equator, and so into Northern and Southern divisions, the Aral Sea and Great Salt Lake are examples of other large bodies of water that are not connected to any of the other oceans

Oceans cover the majority of the earth’s surface - 71% and can have a huge effect on the biosphere.
We get our rainfall from the evaporation of sea water, ocean temperatures are also responsible for climate and wind patterns. Life in the ocean started three billion years before plant and animal life on the earths surface.

The ocean and all ocean life will be permanently affected by the effects of global warming and climate change. Scientists believe that global warming, will cause sea water temperatures to rise, will therefore raise sea levels and change ocean currents effecting all life on earth.

All oceans are regions of oceanic crust’s that are covered with water, an Oceanic crust is a very thin layer of volcanic basalt, that has been solidified, it covers the earths mantle in areas where there are no continents.

The Mediterranean Sea is linked to the World Ocean via the Strait of Gibraltar, over the last few million years the movement of the African continent has closed this strait off totally. The Mediterranean is also linked to the Black Sea via the Bosporus, this is a natural event that occurred over 7,000 years ago.
