Title: Where is the Earth


1
Hydrosphere
  • Where is the Earths water located?
  • What are the processes of the water cycle?

2
What is the hydrosphere?
  • The hydrosphere is all the water on the surface
    of the earth.

3
What is the hydrosphere?
  • The hydrosphere includes oceans, lakes and
    glaciers.

How much of Earths surface is covered by water?
  • More than 70 of Earths surface is covered by
    water.
  • 97 is salt water.
  • 3 is fresh water.

7
How much of Earths surface is covered by water?
  • We can only use a small amount of fresh water
    becausemost fresh water is found frozen in
    glaciers and ice caps. The rest is groundwater or
    water vapour.
  • Only about 0.3 of fresh water is found in
    rivers, swamps and lakes within our reach.

8
What is the water cycle process?
  • 1. EVAPORATION
  • Liquid water becomes water vapour.

9
What is the water cycle process?
  • 2. TRANSPIRATION
  • Plants absorb water from the ground then the
    water evaporates as water vapour.

10
What is the water cycle process?
  • 3. CONDENSATION
  • A gas is changed into a liquid. When cold air
    makes water vapour condense to form clouds.

11
What is the water cycle process?
  • 4. PRECIPITATION
  • Clouds are a mixture of air, water vapour and
    tiny drops of condensed water. These tiny drops
    form into bigger drops and create precipitation
    (water). Precipitation falls from the air as
    rain, hail or snow.

12
What is the water cycle process?
  • 5. SURFACE RUN-OFF
  • Water from precipitation that runs off the
    surface of the Earth, filling lakes, streams,
    rivers and oceans.

13
What is the water cycle process?
  • 6. INFILTRATION
  • Not all water flows into rivers. Some water
    infiltrates through porous land surfaces into the
    ground.
