The Structure of Hydrosphere
  • Oceans96.5 of water found here
  • Fresh water3.5 of water found here
  • Fresh water distribution
  • Ice 1.762
  • Groundwater 1.7
  • Surface Fresh Water 0.014
  • Atmosphere and soil 0.002

Understanding Where Your Water Is LocatedOceans
and Ice
  • What bodies of water hold the largest amount of
    water?
  • Oceansthe largest bodies of water on Earth
    (contain salt water only)
  • What features house water as ice?
  • Icebergs a large piece of freshwater ice
    floating in open waters
  • Glaciers any large mass of ice that moves
    slowly over land
  • permanent snow areas also house water as ice

Fresh Water LocationsSurface Water
  • What is the difference between a watershed and a
    river basin?
  • Both terms describe land that drains into a
    river, stream or lake
  • River Basin the term used to describe an area
    that drains into a large river
  • Watershed the term used to describe an area
    that drains into a smaller river or stream

7
Fresh Water LocationsRiver Basins and Watersheds
  • Larger river basins are made up of many
    interconnected watersheds
  • Example Cape Fear and Neuse River Basins are
    made of many small watersheds
  • The water in a watershed runs to the lowest
    pointa river, stream, lake, or ocean

8
Fresh Water LocationsRivers, Streams, and Lakes
  • What is a river?
  • A large channel along which water is continually
    flowing down a slopemade of many streams that
    come together
  • What is a stream?
  • A small channel along which water is continually
    flowing down a slopemade of small gullies
  • What is a lake?
  • A body of water of considerable size contained on
    a body of land

9
Fresh Water Locations--Groundwater
  • What is groundwater?
  • The water found in cracks and pores in sand,
    gravel and rocks below the earths surface
  • What is an aquifer?
  • A porous rock layer underground that is a
    reservoir for water

10
Other Surface Waters
  • What is a wetland?
  • An area where the water table is at, near or
    above the land surface long enough during the
    year to support adapted plant growth
  • What are the types of wetlands?
  • Swamps, bogs, and marshes
  • Swamp a wetland dominated by trees
  • Bogs a wetland dominated by peat moss
  • Marshes a wetland dominated by grasses
