Most of the Earth is covered in water, including oceans, seas, rivers, lakes, underground in caves and rocks. Water exists in three forms: liquid, solid (ice) and gas (water vapor). The water cycle describes how water evaporates from the oceans into clouds, falls as rain or snow over land, and flows into rivers and lakes before returning to the oceans to repeat the cycle. Rivers have three courses - upper, middle and lower - before reaching the sea. Water is essential for life and is used for drinking, washing, cooking and by plants but must be conserved and not wasted.

2.  MOST OF THE EARTH IS COVERED IN WATER.
WATER
 THE WATER IN OCEANS,THE SEA, RIVERS AND LAKES IS SURFACEWATER.
 THE WATER UNDERGROUBD IN CAVES AND ROCKS IS GROUNDWATER.
 THE WATER IN SEAS AND OCEANS HAS A LOT OF SALT AND IS CALLED
SALTWATER.
 THE WATER IN RIVERS AND MOST LAKES DOES NOT CONTAIN MUCH
SALT AND IS CALLED FRESHWATER.
 BE CAREFUL!!! NOT ALL WATER IS DRINKING WATER

3. W A T E R H A S T H R E E F O R M S :
THE THREE FORMS OF WATER
WATER HAS NO
COLOUR , IT DOES
NOT SMELL AND
DOES NOT TASTE
OF ANYTHING.
LIQUID WATER CAN
CHANGE FORM.WHEN
WE COOL WATER WE
MAKE ICE (SOLID
WATER).WHEN WE
HEAT WATER IT
PRODUCESWATER
VAPOUR (WATER IN
THE FORM OF GAS)
LIQUID, SOLID AND VAPOUR.

4. THE WATER CYCLE
1.- THE SUN HEATS THE
WATER IN THE SEA. THIS
WATER EVAPORATES AND
FORMS CLOUDS.
2.- THE WIND MOVES THE
CLOUDS. THEY COOL AND
IT RAINS OR SNOWS.
3.- THE WATER FALLS
INTO LAKES AND RIVERS.
4.- THE WATER FROM
RIVERS AND LAKES GOES
TO THE SEA AND THE
CYCLE STARTS AGAIN.

5. RIVERS
THE COURSE OF A RIVER.
 UPPER COURSE: A RIVER BEGINS IN THE MOUNTAINS.
 MIDDLE COURSE: THE RIVER CONTINUES DOWN
THE MOUNTAINS AND HILLS
 LOWER COURSE: THE RIVER GOES INTO THE SEA.
 RIVERS HAVE 3 COURSES:

6. WE USE WATER TO:
USE OFWATER
WATER PLANTS
WASH
DRINK
COOK
DON’T WASTE WATER!!
Have a shower.
Turn off the tap
when you brush
your teeth.
Keep tap water in
the fridge.

7. THE GROUND
 SAND, SOIL AND ROCK COVER THE GROUND.
 MOST ANIMALS LIVE ON THE SURFACE,
BUT SOME LIVE UNDERGROUND.
 PLANTS GROW IN THE GROUND.
PROTECT OUR PLANET!!
 PUT THE RUBBISH IS THE BIN. DO NOT
LEAVE PLASTIC BAGS, PAPER OR GLASS ON
THE GROUND. IT IS BAD FOR PLANTS AND
ANIMALS!
