The document summarizes key aspects of the atmosphere and weather. It describes the main layers of the atmosphere, including the troposphere where weather occurs. It also explains that the atmosphere contains gases like nitrogen, oxygen, and water vapor. Greenhouse gases like carbon dioxide and methane trap heat in the atmosphere and contribute to the greenhouse effect. The document outlines factors that influence weather and issues like global warming from rising greenhouse gas levels.

2. The atmosphere is made
oh many gases. It
contains water in three
form:
A gas, called vapor, ice
cr ystals and droplets.
OTHER GASES: Argon,
neon kypton and xenon,
and harmful chemical
like nitrogen dioxide.
The atmosphere pushes
down on Ear th with a
force called air pressure
or atmospheric pressure.

3. THERE ARE FIVE LAYERS IN THE
ATMOSPHERE.
 THE TROPOSPHERE IS WHERE
WEATHER OCCURS.
 MANY AIRPLANES FLY IN THE
STRATOSPHERE BECAUSE IT IS VERY
STABLE.
 MANY ROCKS FRAGMENT FROM
SPACE BURN UP IN THE
MESOSPHERE.
 THE THERMOSPHERE IS VERY THIN.
5. THE UPPER LIMIT OF OUR
ATNOSPHERE IS THE EXOSPHERE.

5.  The aurora is formed
 The ozone is a gas a when particles from the
layer in the Sun enter the Earth’s
stratosphere. atmosphere.
 This layer absorbs high-
energy UV (ultraviolet
light) rays from the sun,
protecring us from
them.

6.  The greenhouse effect is the trapping of heat
around Earth.
 A tiny number of gases in the atmosphere can
trap heat around the Earth. This gases keep
the Earth warm.

7.  The traced gases 1%
regulate the
climate.
 These are the
gases:
Water
vapour.

8. The greenhouse gases:
Carbon dioxide.
Methane
Nitrous oxide
Ozone
Halocarbons
CFCs

9.  Not all the heat we feel on Eath comes from the
Sun. Most of this heat comec from Eath itself,
whitch is tappet and sent back down by
greenhouse gases.

10.  As Earth warms up, it gives heat as low-energy
infrared rays.
 Only a few pass through the greenhouse gases.

11.  The greenhouse gases trap most of infrared
rays. This heats the atmosphere and heats the
Earth.

13.  1. Recycle and Reuse.
 2. Consider alternative energy methods.
 3.Save power and conserve household energy.

14.  Is when the greenhouse effect gets stonger, the
Earth’s average temerature rises. The
conditions on Earth start to change.

15.  Three R:
Recycle
Reduce
Reuse

16.  Most governments are worried about rising
greenhouse gas levels in the atmosphere, and
defect they may have.
 In 1997, representatives from 160 countris
met in kyoto, Japan to create the kyoto
protocol.

17.  1. The Sun’s energy is turned into power by the
solar panels.
 2.Natural heat from beneath Earth’s surface is
the geothermal energy.
 3. Hydroelectric power stations, flowing water
from a dam, generate power.
 4. Wind farms and wave power use the motion
oh the sea or air to move the huge turbines.
