The earth’s hydrosphere

  1. 1. THE EARTH’S HYDROSPHERE<br /><ul><li>The Earth’s liquid water constitutes the hydrosphere.
  2. 2. The vast majority of Earth’s water is in the oceans (salt water), with smaller, but geologically important, quantities of fresh water in lakes, rivers, and ground water.
  3. 3. The components of the hydrosphere, as well as the cryosphere (frozen water), the atmosphere, and the biosphere, participate in the global hydrologic cycle.
  4. 4. Earth’s water supply has had, since Earth was created, major influences on Earth’s climate, its landscape and mineralogy, the composition of its atmosphere, and on the origin and evolution of life.
  5. 5. The total mass of Earth’s water is about 300 times the mass of the atmosphere.
  6. 6. Without water, which facilitates the formation of carbonate rock, the atmospheric content of CO2 would be far higher than it is.</li></li></ul><li> Volume Percent of Total_<br />OCEANS 1,350 x 1015 m3 97.3<br />CRYOSPHERE 29 x 1015 m3 2.1<br />(Glaciers & Polar Ice)<br />UNDERGROUND 8.4 x 1015 m3 0.6<br />(Aquifers)<br />LAKES & RIVERS 0.2 x 1015 m3 0.01<br />ATMOSPHERE 0.013 x 1015 m3 0.001<br />BIOSPHERE 0.0006 x 1015 m3 4 x 10-5<br />THE EARTH’S HYDROSPHERE:Distribution of Water on Earth<br />
