Thus, our picture of Venus at around the time life was getting started on earth is one of warm oceans, probably rich with organic molecules splashing around rocky shores and volcanic vents.
From these studies, scientists have concluded that the surface of the primitive Earth was covered with oceans containing the molecules fundamental to life.
Stephanie Dutkiewicz, a scientist in MIT's Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century.
The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past.
Clouds are formed from the evaporation of the oceans' water that is warmed by the Sun and rises high into the atmosphere, condensing in tiny droplets on minute particles of dust.
Heavier isotopes tend to be left behind when water evaporates from the ocean surfaces, the remaining ocean water becomes progressively enriched in oxygen 18.
Marlin finds himself the unlikely hero on this epic13 journey. And the oncefearful Marlin becomes a true hero in the eyes of his son, and the entire ocean.
In the colorful and warm tropical waters of the Great Barrier Reef2, a Clown-fish named Marlin lives safe and secluded in a quiet cul-de-sac3 with his only son, Nemo.
