The atmosphere is the air that surrounds us and makes up
the environment we live in. It is composed of a mixture of
gases, primarily nitrogen and oxygen, and is made up of
layers with different temperatures, pressure, and chemical
composition.

composition.
COMPOSITION OF THE
ATMOSPHERE
The composition of the Earth's atmosphere
is predominantly made up of nitrogen and
oxygen gases, with smaller quantities of
carbon dioxide, helium, ozone, argon,
hydrogen, and dust particles. This diverse
mixture plays a crucial role in sustaining life
on our planet.

STRUCTURE OF
THE ATMOSPHERE
The troposphere is the closest to the Earth's surface and is the layer
in which we live. It extends from the surface up to around 10-15 km
and is characterized by temperatures that decrease with altitude.
