  1. WATER CLASS VI

  2. USES OF WATER • DRINKING • BRUSHING • WASHING UTENSILS,CLOTHES,VEHICLES • CLEANING PLATES, FLOOR • PRODUCING ELECTRICITY • AGRICULTURE, GARDENING • USED IN INDUSTRIES

  3. NEARLY 2/3 OF EARTH IS COVERED WITH OCEAN/SEA WATER

  4. WATER IN OCEANS AND SEAS IS SALTY [SALINE] AND UNFIT FOR DRINKING , INDUSTRIAL PURPOSE AND AGRICULTURE

  5. SOURCES OF FRESH WATER • 1.RIVER

  6. 2.SPRING

  7. 3.POND

  8. 4.WELL

  9. 5.HAND PUMP

  10. WATER IN TAPS COME FROM RIVER USUALLY

  11. Cycling of water in nature- WATER CYCLE • Basic processes in water cycle • 1.EVAPORATION • 2.CONDENSATION • GAS [VAPOUR] • LIQUID [WATER] cooling evaporation condensation heating

  12. EVAPORATION • THE PROCESS OF TURNING WATER TO WATER VAPOUR BY HEATING. WATER EVAPORATES FROM WATER BODIES AND OTHER SOURCES DUE TO SUN’S HEAT

  13. THIS WATER VAPOUR JOINS THE ATMOSPHERE CONTINUOUSLY AS A SLOW PROCESS. • WATER VAPOUR ALSO REACHES THE ATMOSPHERE BY TRANSPIRATION IN PLANTS.

  14. FORMATION OF CLOUDS • THE WATER VAPOUR MOVES UP AND UNDERGO COOLING , AND CONDENSATION TO FORM CLOUDS.

  15. MANY TINY DROPLETS OF WATER IN THE CLOUD COME TOGETHER TO FORM LARGER DROPS WHICH ARE HEAVIER AND FALL AS RAIN.

  16. CONDENSATION • THE PROCESS BY WHICH WATER- VAPOUR TURNS TO WATER ON COOLING.

  17. EXCESSIVE COOLING OF WATER VAPOUR RESULTS IN SNOW FALL / HAIL

  18. THE WATER THAT FALLS ON LAND AS RAIN AND SNOW AGAIN UNDERGO CIRCULATION RAIN WATER SURFACE RUN OFF JOIN RIVERS LAKES AND OCEAN INFILTRATION GO DEEP IN THE SOIL SOIL WATER USED BY PLANTS GROUND WATER SOUCE FOR BOREWELL

  19. WATER CYCLE

  20. Ground water is an important source of water

  21. DEPLETION OF WATER TABLE infiltration • Water table may go down if the water is not sufficiantly replenished. Consumption of ground water Ground water

  22. REASONS OF DEPLETION OF WATER TABLE • 1. DEFORESTATION

  23. 2 . SCANTY RAINFALL

  24. 3.EXCESSIVE CONSUMPTION BYINCREASING POPULATION

  25. DECREASE IN THE SEEPAGE AREA

  26. 5. EXCESSIVE USE BY Agricultural activities

  27. 6. INCREASING INDUSTRIES

  28. CONSERVATION OF WATER • AVOID WASTAGE

  29. CONSERVATION OF WATER • REPAIR LEAKING TAP

  30. CONSERVATION OF WATER

  31. CONSERVATION OF WATER • REUSE /RECYCLE IF POSSIBLE

  32. WATER WISE HABITS DIRECT USED KITCHEN WATER TO YOUR GARDEN .

  33. Drip irrigation for your garden

  34. WATER WISE HABITS • WASH VESSELSUSING COLLECTED WATER INSTEAD OFWASHING DIRECTLY UNDER TAP.

  35. WATER WISE HABITS • MOP THE FLOOR INSTEAD OF WASHING

  36. WATER WISE HABITS • TURN OFF TAP WHILE BRUSHING

  37. ROOF TOP RAINWATER HARVESTING • RAINWATER IS COLLECTED FROM THE ROOF OF BUILDINGS AND STORED IN TANKS AFTER FILTRATION.

  38. Roof top rainwater harvesting

  39. SURFACE RUN OFF WATER PERCOLATION

  40. PLANTING VEGETATION

  41. Roof to rainwater harvesting

  42. POND- A TRADITIONAL WAY OF COLLECTING WATER

  43. INFILTRATION PITS • IT SOAKS WATER & DIRECT IT TO UNDER GROUND TO RECHARGE GROUND WATER Pit filled with gravel

  44. GRASSY PATCHES & OTHER VEGETATIONS • HELPS IN INFILTRATION

  45. DRIP IRRIGATION- saves water • A TECHNIQUE OF WATERING PLANTS BY USING NARROW TUBES WHICH SUPPLY WATER AT THE BASE OF PLANTS AS TINY DROPS.

  46. DRIP IRRIGATION

  47. IF IT RAINS HEAVILY---CAUSES FLOOD

  48. NO RAIN FOR A LONG PERIOD –CAUSES DRAUGHT

  49. Save every drop of water !
