Atmosphere is a layer of gasses surrounding the earth
The atmosphere is made up of oxygen, nitrogen, argon
carbon dioxide, some of helium, hydrogen, ozone gasses
and water vapour dust particles.
Atmosphere protects the life on earth by absorbing
ultraviolet solar radiation.
Without atmosphere life wouldn’t exist on earth.
Atmosphere warms up the earth by the process of green
house effect. It helps reduce the extreme temperatures
between day and night.

5 layers determined by whether temperature increases or decreases
with altitude. From highest to lowest, these layers are:

Exosphere: The exosphere is the uppermost layer of
the atmosphere.

Thermosphere: The thermosphere is the biggest of all the layers of
the earth's atmosphere directly above the mesosphere and directly
below the exosphere. International space station orbits in this layer.

Mesosphere: The mesosphere extends from the stratopause to 80–
85km (260,000–280,000 ft). It is the layer where most meteors burn
up upon entering the atmosphere.

Stratosphere: The stratosphere is the second major layer of Earth's
atmosphere, just above the troposphere, and below the
mesosphere.

Troposphere: The troposphere begins at the surface and extends to
between 7 km (23,000 ft) at the poles
 Ozone
layer protects the earth from harmful
rays from the sun
 It protects life
 Ozone gases exist in the
stratosphere.
 Absorption of UV radiation.
 Photochemical smog in
troposphere.
 Emission test on cars every
two years.
 Definition:
A natural process whereby gases and
clouds absorb infrared radiation emitted
from the Earth’s surface and radiates it,
heating the atmosphere and Earth’s surface.

The greenhouse effect is the rise in
temperature that the Earth experiences
because certain gases in the atmosphere
(water vapour, carbon dioxide, nitrous oxide,
and methane, for example) trap energy from
the sun. Without these gases, heat would
escape back into space and Earth’s average
temperature would be about 60ºF colder.
Because of how they warm our world, these
gases are referred to as greenhouse gases.

Weather
 State of the atmosphere, including temperature,
precipitation, wind, and humidity in a particular
location over a short period of time.
 Climate
 The average of the weather in a region over a
long period of time.
 Climate Change is the change in the statistical
distribution of weather over periods of time,
that ranges from decades to millions of years.
Climate change can be limited to a specific
region or it may occur across the whole earth.

they call Global Warming
