Oceanography is a very important discipline for understanding the oceans, which are essential for all life on Earth and cover the majority of the Earth's surface. Oceanography is extremely multidisciplinary, covering the physics, chemistry, geology and biology of the world's oceans. No understanding of Earth's climate or the chemical cycles essential to life is complete without the insights of oceanography.Know More
Oceanography covers both the deep oceans and the much shallower coastal regions. The breadth of knowledge in oceanography means oceanographers tend to be rather specialized around one specific subject. Many different sorts of tools and instruments are used in oceanography. While ships are certainly a part of this, other methods, such as stationary underwater observatories, are also used to study the ocean. Modern oceanographers also use automated underwater vehicles and sophisticated scanning devices to uncover information more quickly than direct human effort could accomplish.
The importance of oceans to life cannot be overstated, even on land. Oceans are a critical source and absorber of heat, moderating worldwide temperatures. Also, the majority of oxygen generation comes from single-celled algae in the oceans, not from land plants. As the bodies containing the vast majority of water on Earth, oceans are also the major source of cloud formation and thus, a driver of weather.Learn more about Environmental Science
As the wind hits the surface of the water, the energy transfer of the wind to the water causes the water level to rise and fall, producing waves. To generate wave energy, a technological device that sits in the water is then used to make electricity from the waves, and a cable is used to transfer this electricity to the power grid for use. One of the main benefits of this type of energy is that it is highly renewable.Full Answer >
An ice age is a long period of time in which the average temperature on Earth is greatly reduced. The reduction in the Earth's temperature results in an expansion of the continental ice sheets, polar ice sheets and mountain glaciers.Full Answer >
Global winds help to distribute heat and water vapor around the Earth, which influences temperature and precipitation patterns around the entire globe. Global winds are caused by pressure differences in the atmosphere from warm air rising to the poles. The flowing air carries water vapor and creates specific weather patterns, such as increased rainfall in the tropics.Full Answer >
In ecology, a community refers to a grouping of species living collectively and interactively with the environment in a specified area, while the term biosphere refers to the total extent of all of the ecological systems on Earth. The natural communities in an ecosystem can change in a process referred to as succession, which can encompass lengths of time ranging between a few years and centuries. In the biosphere, the totality of living organisms on Earth have been interacting with each other and the elements of the hydrosphere, lithosphere and atmosphere for what is believed to be a span of about 3.5 billion years.Full Answer >
