  2. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Bernoulli's principle is a key concept in fluid dynamics that relates pressure, density, speed and height. Bernoulli's principle states that an increase in the speed of a parcel of fluid occurs simultaneously with a decrease in either the pressure or the height above a datum. [1]:

  3. Tide - Wikipedia

    en.wikipedia.org/wiki/Tide

    Since the Sun and the Moon have practically the same diameter in the sky, the tidal force of the Sun is less than that of the Moon because its average density is much less, and it is only 46% as large as the lunar, [f] thus during a spring tide, the Moon contributes 69% while the Sun contributes 31%.

  4. Tidal range - Wikipedia

    en.wikipedia.org/wiki/Tidal_range

    Mean ranges near coasts vary from near zero to 11.7 metres (38.4 feet), [4] with the range depending on the volume of water adjacent to the coast, and the geography of the basin the water sits in. Larger bodies of water have higher ranges, and the geography can act as a funnel amplifying or dispersing the tide. [5]

  5. Meteorology (Aristotle) - Wikipedia

    en.wikipedia.org/wiki/Meteorology_(Aristotle)

    The terrestrial region was composed of the four elements: water, earth, fire, and air; These elements were arranged in spherical strata, with Earth as its center and the Moon on the outskirts of the sphere; They were in constant interchange with one another, e.g: heat from the Sun collides with cold water, creating air and mist

  6. Orders of magnitude (pressure) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(pressure)

    Water pressure of a garden hose [58] 300 to 700 kPa 50–100 psi Typical water pressure of a municipal water supply in the US [59] 358 to 524 kPa: 52-76 psi Threshold of pain for objects outside the human body hitting it [60] 400 to 600 kPa 60–90 psi Carbon dioxide pressure in a champagne bottle [61] 520 kPa 75 psi

  7. Aphotic zone - Wikipedia

    en.wikipedia.org/wiki/Aphotic_zone

    Depending on how it is defined, the aphotic zone of the ocean begins between depths of about 200 m (660 ft) to 800 m (2,600 ft) and extends to the ocean floor. [ 1 ] [ 2 ] [ 3 ] The majority of the ocean is aphotic, with the average depth of the sea being 4,267 m (13,999 ft) deep; the deepest part of the sea, the Challenger Deep in the Mariana ...

  8. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The water cycle is powered from the energy emitted by the sun. This energy heats water in the ocean and seas. Water evaporates as water vapor into the air. Some ice and snow sublimates directly into water vapor. Evapotranspiration is water transpired from plants and evaporated from the soil. The water molecule H

  9. Sea - Wikipedia

    en.wikipedia.org/wiki/Sea

    Earth is the only known planet with seas of liquid water on its surface, [3]: 22 although Mars possesses ice caps and similar planets in other solar systems may have oceans. [11] Earth's 1,335,000,000 cubic kilometers (320,000,000 cu mi) of sea contain about 97.2 percent of its known water [12] [c] and covers approximately 71 percent of its ...
