How the Water Cycle Work
Solar energy evaporates exposed water
from seas, lakes,rives, and wet soil; the majority of this ecaporation takes places over
the seas. Water is also released into the atmosphere by the plants through photosynthesis. During this prosess, known as
evapotranspiration, water vapour rises into
the atmosphere
Clouds from when air becomes saturated
with water vapour. The two major types of
cloud fomation are stratified or layered grey
clouds called status and billowing white or
dark grey cloud called cumulus. Nimbostratus clouds and cumulonimbus cluods are the
two cloud types that are associated with rainy
weather; nimbostratus clouds will bring
steady rain, and cumulonimbus couds will
bring stromy wather.

Precipitation as rain, or hail ensures that
water return to Earth’s surface in a fresh
form . Some of this rain, however, falls into
the seas and is not accessible to human.
When rain falls, it either washes down hill
slopes or seeps underfround; when snow
and hail melt, this water may also sink into
the ground.

You’d better keep your promise
I admit I forgot to turn out the light
I’m afraid that wasn’t true, Mom
I do apologise,Mom
OkK, it,s my fault

Acid Rain
Acid rain is rain that is highly acidic because of sulphur,nitrogen oxidesmand other
air pollutans dissolved in it. Normal rain is
slightly acidic, with a pH of 6. Acid rain may
have a pH value as low as 2.8.
Acid rain can severely damage both plant
and animal life. Certain lakes, for example,have lost fist and plant life because of

acid rain.
Acid rain comes from sulphur in coal
and oil. When they burn, they make sulphur
dioxide (SO2). Most sulphur leaves factory
chimneys as gaseous sulphur dioxide (SO2)
and most nitrogen is emitted as nitrogen oxides (NO or NO2), both of which are gases.
The gases may be dry deposited-absorbed
directly by the land, by lakes or by the surface vegetation, If they are in the atmospgere for any time, the gases will oxidise (gain
an oxygen atom) and go into solution as acids. Sulphuric acid (H2SO4) and the nitrogen
oxides will become nitric acid (HNO3). The
acids usually dissolve in cloud droplets and
may travel great distance before being precipitated as acid rain. Catalysts such as hydrogen peroxide, ozone and ammonium help
promote the formation of acids in clouds
ammonium (NH4) can be formed when
some of the acids are partially neutralised by
airborne ammonia (NH3). Acidification increases with the number of active hydrogen
(H+) ions dissolved in acid. Hydocarbons
emitted by for example, car exhausts will react in sunlight with nitrogen oxides to produce ozone. Althgough it is invaluable in the
atmosphere, low level ozone causes respiratory problems and also hastens the formation of acid rain.
When acid rain falls on the ground it dissolves and liberates heavy metals and alumunium (AI). When it is washed into lakes, alumunium irritates the outer surfaces of many

fish. As acid rain falls or drains into the lake
the pH of the falls. Forests suffer the effect
of acid rain through damage to leaves,
through the loss of vital nutrients, and
through the increased amounts of toxic metals liberated by acid, which damage roots and
soil micro organisms.

What Does Rain Come from?
Rain always comes from clouds. But
where do clouds come from? How does all
that water get into the sky?
Think about your bathroom. There is
hot water in your bath. Steam goes up from
the hot water. The steam makes small clouds
in the bathroom. These warm clouds meet
the cold walls and windows, and then we see
small drops of water on the walls and windows.
The world is like your bathroom. The
water is in the oceans warms when the sun

shines on it. Some of this water goes up into
the sky and makes clouds. The wind carries
the clousds for hundreds of kilometres.
Then the clouds meet cold air in the sky, and
we see drops of water. The drops of water
are rain.
The rain falls and runs into rivers. Rivers
run into oceans. And the water from oceans
makes clouds and more rain. So water is always moving from oceans. So the rain on
your head was on other heads before! The
water in your gardaen was in other garden in
other countries.
(1) Rain doesn’t always come from clouds.
(2) Steam rises from the hot water.
(3) The water in the oceans warms when
the sun shines on it.
(4) Some of the water goes down into the
sky and makes clouds.
(5) The rain falls and runs into rivers
