L7-L9 | WATER, SOIL, WASTE RESOURCES

• WATER INVOLVES -> WATER CYCLE:

  1. evaporation
  2. condensation
  3. precipitation
• WATER DISTRIBUTION

  • 71% water
  • 97% ocean water
  • 3% fresh water
• WATER SOURCES:

  1. surface water
  2. ground water
• SURFACE WATER

  • Water collects on the surface of the earth
  • Maintained by rainfall or other precipitation
• SURFACE WATER SOURCES:

  1. river
  2. lake
  3. gulf
  4. dam
  5. sea
  6. ice caps
  7. glaciers
  8. bay
• GULF

  large inlet from an ocean into a landmass, typically narrower opening than a bay.
• RIVER

  Naturally flowing water course
• LAKE

  An area filled with water, localized in a basin that is surrounded by land.
• DAM

  Barrier that stops or restricts the flow of water or underground stream
• SEA

  Expanse of salt water
• ICE CAPS

  Mass of ice that covers less than 50,00 km2 of land area
• GLACIERS

  Persistent body of dense ice that is constantly moving under its own weight
• BAY

  Recessed, coastal body of water that directly connects to a larger main body of water.
• 2. GROUNDWATER

  • Water is found beneath the surface of the Earth in conditions
• SOURCES OF GROUNDWATER

  1. open wall
  2. tube wall
  3. artesian walls
  4. infiltration
  5. springs
• OPEN WALL

  A hole in the ground
• TUBE WALL

  Tube is underground
• ARTESIAN WALLS

  Simply a wall that doesn’t require a pump to bring water to the surface
• INFILTRATION

  Flow of water from above ground into subsurface; interception walls
• SPRINGS

  Result of an aquifer being filed to the point that the water overflows onto the land surface
• SOIL RESOURCES:

  1. agricultural land
  2. housing
  3. community / industry
• HUMAN ACTIVITIES THAT DAMAGE SOIL RESOURCES:

  • farming
  • construction and development
  • mining
  • waste disposal
• 3 TYPES OF WASTE

  • solid
  • liquid
  • gas
