“It is the origin of all life on earth,
the substance from which Allah
created man.”
(Al-Furqan 25:54)
Journey of Water Drop
Hi I am water drop and I am going
to Share my Journey on Earth…

A water drop journey never ends… It begins in rivers, lakes, and oceans and keeps
on moving in circles which is a process we called as “WATER CYCLE”. So the water on
the Earth a long time ago is the same water we have now.
Water can take many forms. It can be a liquid, a solid, or a gas. Think about when
ice cubes melt in your glass, that's an example of water in a solid form changing into a
liquid form.
I could really begin this story anywhere along the cycle, but I think the ocean is the
best place to start, since that is where most of Earth's water is… If the drop wanted to
stay in the ocean then it shouldn't have been sunbathing on the surface of the sea. The
heat from the sun found the drop, warmed it, and evaporated it into water vapor. So
water goes through something called “EVAPORATION”… Think of it as a stream coming
from a pan when you are boiling eggs or spaghetti.
It rise as tiny "droplets" into the air and continue rising until strong winds aloft
grab it and take it hundreds of miles until it is over land. There, warm updrafts coming
from the heated land surface take the droplets (now water vapor) up even higher, where
the air is quite cold.
DO YOU KNOW?
Each day the sun evaporates a trillion tons of water.

When the vapor gets cool it change back into a liquid. If it was cold enough, it
would have turned into tiny ice crystals, such as those that make up cirrus clouds. The
vapor condenses on tiny particles of dust, smoke, and salt crystals to become part of a
cloud. This process is called “CONDENSATION”… It is also the reason water droplets
form on the outer surface of cold water.
Once a cloud is filled with many water droplets the droplets fall to earth. This is
the process of “PRECIPITATION”. Water can fall in the form of snow, rain, sleet or hail.
Earth's gravity helps to pull them down to the surface. Once they start falling there are
many places for water drops to go. Maybe they would land on a leaf in a tree, in which
case it would probably evaporate and begin its process of heading for the clouds again. If
it misses a leaf there are still plenty of places to go…
DO YOU KNOW?
The earth's total amount of water has a volume of about 344 million cubic miles.

When water reaches the ground, it travels back to the ocean through streams and
rivers. This is called “Runoff”. Not all water runs off, it can be absorbed by plants or soil.
In this case it might sink into the ground to begin its journey down into an underground
aquifer as groundwater. The drop will continue moving downhill as groundwater, but the
journey might end up taking tens of thousands of years until it finds its way back out of
the ground. Water can also runoff to sewers as well. It leaves the ground through a plant
by the process of “TRANSPIRATION”… From these places, it is back again either into the
air, down sewers into rivers and eventually into the ocean, or back into the ground
restarting the steps of water cycle.
A lot of surface water is used for irrigation. Even more is used by power production
facilities to cool their electrical equipment. From there it might go into the cooling
tower to be reused for cooling or evaporated. Maybe a town pumps the drop out of the
river and into a water tank. From here the drop could go on to help wash your dishes,
fight a fire, water the tomatoes, or flush your toilet… Maybe the local steel mill will grab
the drop, or it might end up at a fancy restaurant mopping the floor. The possibilities are
endless. But it doesn't matter to the drop, because eventually it will get back into the
environment. From there it will again continue its cycle into and then out of the clouds,
this time maybe to end up in the water glass of the Prime Minister of Pakistan… Hence
the life of water drop is never ending.

Let’s have a look at quick trip back into the atmosphere as water vapor …this is it.
WHY WATER IS SO IMPORTANT?
It is important because every animal and plant must have water to live. Two-thirds of your body is made up
of water. But most of the world's water is not available for drinking. Ninety-seven percent of Earth's water is salt
water. The rest of the water is frozen in glaciers and some is polluted. Clean, fresh water is important.
Each day almost 10,000 children under the age of 5 in Third-World countries die as a result of illnesses
contracted by use of impure water. If all new sources of contamination could be eliminated, in 10 years, 98% of all
available groundwater would then be free of pollution.
