The Earth's Spheres and Where Water Comes From
1. The Earth and its living World
Where do you get water from?
2. On the surface of the
earth, there is
some land and
water
Spheres of the Earth
Lithosphere - Land
Hydrosphere - Water
Atmosphere - Air
constituents
Biosphere - Living things.
4. Continent
Large or Vast continuous stretch of Land.
Divided into seven continents Africa, Asia,
Europe, North America, South America
Australia, Antarctica
5. Land forms
Land is not even in all places
Give rise to different shapes
eg. Plain, Hill, Mountain
6. Hydrosphere
2/3 part of earth
covered with water.
Water part is divided
into : Ocean- salty
water, Surface water
and fresh water
7. Oceans
Salty water - five oceans Atlantic, Pacific, Arctic,
South Ocean, Indian Ocean.
Land along margins of ocean called coastal
region
Water bodies of different shapes and sizes.- sea,
bay, strait, Gulf etc.
8. Rivers
Fresh water reservoirs
streams of water flowing over the land
Streams are - Rills, Brook, Rivers
Rills, brooks, streams - join to form rivers
Rivers join to make bigger river tributaries
Rivers cascade down a sudden drop - water fall
Rivers flow to the ocean.
10. Ice form of water, Glacier
water particles in the clouds freeze in cold
regions
come down in the form of snow
Layer of snow pile up on ground to form ice.
In low - lying area ice pile become huge mass
slips down; a slope - glacier
Blocks of ice floting in sea- Iceberg
11. Groundwater- (Well)
water stored in underground layer
well, bore wells, under ground springs
Hydro Sphere :water on earth is surface,
Ground water, Water vapours
12. Atmosphere
Air around Earth
Higher from the surface air becomes rarer.
Consists- mixture of gases, nitrogen, oxygen,
water vapour, carbon dioxide
Layers of Atmosphere
Troposphere, Stratosphere, Mesosphere
Ionosphere, Exosphere
13. Troposphere
13 km from earth's surface
conditions changes continuously
Go higher in troposphere air becomes cooler
Weather related phenomena rain, fog, clouds, Winds, Storms.
Aeroplanes fly in higher parts (mountaineers)
16. Water evaporates due to
sun's heat
Water vapour lighter than air,
Goes higer,cools,condenses-
Fine drop lets of water
Droplets forms clouds.
Smaller droplets Bigger drop
can not float
Fall down on the earth- Rain
17. Water Cycle
Rain water flows into rills, streams, rivers and
finally into sea
Evaporation of this water
Condensation, rainfall continuously processes
are done
18. Biosphere
Variety of living things in different regions.
Snowbound polar-bear , Africa –Zebras,
Australia-Kangaroos, Hot climate- Elephants,
Lions.
Living things exist in litho, hydro, atmo
Living world- biosphere
19. Plants, animals, microbes are dependent on one
another
Biosphere is where living things take birth, live
and die
20. Three Layer of Earth
Earth is surface
occupied by land 1/3
and water 2/3
Litho - soil, rock
Hydro - Salty, fresh
water reservoir
Atom –Tropo, strato
Bio - All living things
