Water Resources ppt scinece project

  1. 1. Water Resources So. Science PPT
  2. 2. Contents:       Introduction. Prior Knoledge. About Water resources. Division of water resources. Source of Water resources. Uses of Water.
  3. 3. Introduction: This is virtual booklet of water resources is going to be about how people use water, how we would have to take care of it and many things that with this booklet you should learn. Also with this booklet you should learn how to not waste the water and enjoy you to practice it to save this beautiful world.
  4. 4. Prior knowledge: Are sources of water and they are useful from the humans and animals. Water resources is important on Earth and without it we can’t do many things or satisfied our needs. We would have to take care of the water because in few years there's not going to be enough water for us. Water is a renewable natural resources also like air and soil.
  5. 5. About Water resources:   Fresh water is renewable resources like soil and air. The worlds is supplied by clean and fresh water and itis decreasing. Water is one of our most critical resources, but around the world it is under threat. Water demand already exceeds supply in many parts of the world and as the world population continues to rise, so too does the water demand.
  6. 6.  Are sources of water that are useful to humans. Uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water.
  7. 7. Division of Water resources: Water resources are divisible into two distinct categories : the surface-water resources and the ground-water resources. Each of these categories is a part of the earth's water circulatory system, called the hydrologic cycle, and is derived from precipitation, which is rainfall plus snow.
  8. 8. Distribution of water:
  9. 9. Source of fresh water:
  10. 10. Ground Water: Sub-surface water, or groundwater, is fresh water located in the pore space of soil and rocks. It is also water that is flowing within aquifers below the water table. Desalination: Desalination is an artificial process by which saline water (generally sea water) is converted to fresh water.
  11. 11. Frozen Water: Several schemes have been proposed to make use of icebergs as a water source, however to date this has only been done for novelty purposes. Glacier runoff is considered to be surface water.
  12. 12. Uses of water:  Agricultural: It is estimated that 69% of worldwide water use is for irrigation, with 15-35% of irrigation withdrawals being unsustainable. Aquaculture is a small but growing agricultural use of water. Industrial: It is estimated that 15% of worldwide water use is industrial. The distribution of industrial water usage that is varies widely, but as a whole is lower than agricultural use.
