3. What is Atmosphere?
The atmosphere is a mixture of
gases that surrounds the Earth. It
helps make life possible by providing
us with air to breathe, shielding us
from harmful ultraviolet (UV) radiation
coming from the Sun, trapping heat
to warm the planet, and preventing
extreme temperature differences
between day and night.

11. Between 15 km and
30 km above the
earth
The ozone layer is a thin
part of Earth's
atmosphere that absorbs
almost all of the sun's
harmful ultraviolet light.
"Ozone holes" are
popular names for areas
of damage to the ozone
layer. This is inaccurate.
Ozone layer damage is
more like a really thin
patch than a hole.

13. The greenhouse effect is a natural phenomenon that warms the
Earth's surface. It occurs when some of the sun's energy that
reaches the Earth is trapped by gases in the atmosphere, such
as carbon dioxide, methane and water vapor. These gases act
like a blanket, preventing some of the heat from escaping back
into space. The greenhouse effect is essential for life on Earth, as
it keeps the planet at a comfortable temperature. However,
human activities have increased the concentration of greenhouse
gases in the atmosphere, causing more heat to be trapped and
leading to global warming and climate change.
