Also, without the redistributions of heat energy by the ocean currents and atmosphere, the tropics would be much hotter, and the polar regions much colder. Weather can have both beneficial and harmful effects. Extremes in weather, such as tornadoes or hurricanes and cyclones, can expend large ...
The gases in our atmosphere and the climate conditions that result are NOT stable and are constantly changing over time. Many factors play into this including solar activity, volcanic activity, shifts in ocean currents and atmospheric currents, photosynthesis (plants converting atmospheric CO2 into ...
This amazing fact shows how much there is to discover in the ocean. Marine biologists are important because they are dedicated to studying this huge and complicated world. They explore the ocean using tools like scuba diving, submersibles, remote-operated vehicles, and advanced genetic analysis. ...
