Natural treasures are the elements and
resources that nature provides, crucial
for the survival of all living beings and
improving our quality of life. 
These treasures include air, water,
sunlight, soil, plants, animals, and
minerals. 
Each of these resources plays a crucial
role in maintaining ecological balance
and supporting life on Earth.

The air we breathe contains oxygen.
Our body requires oxygen to work
properly.
If we hold our breathe for too long, we
don't get enough oxygen, affecting our
ability to function. Thus, oxygen is
essential for our survival.
Similarly, most living things also depend
on oxygen to live.

Composition of Air
Air is a mixture of gases and it mainly
consists of:
Nitrogen (78%): This is the most
common gas in the atmosphere, and it
does not support burning.
Oxygen (21%): This gas is essential for
breathing and burning.
Other Gases (1%): This includes argon,
carbon dioxide, neon, helium, methane,
and a few others.

Characteristics of Air
Air is invisible, but its presence can be
observed through its effects. For
example:
Wind: Moving air, which can vary
from gentle breezes to strong
storms.
Physical Effects: Rustling leaves,
fluttering pages of a book, or
swaying clothes on a clothesline.
