What is air?
Air is a natural resource surrounding us. It's
invisible but can be felt when it moves – like
a friendly hug from nature.
Breathing: We need air to breathe. When we
breathe in, our lungs take in the oxygen from the
air, and that helps our body stay alive.
1.
Wind: Air makes wind. It can be a gentle breeze or
a strong wind. Wind can help kites fly and move
leaves and branches on trees.
2.
Weather: Air is part of the weather. It can be
sunny, rainy, or windy. Air helps make clouds and
rain.

the air.
1.
When we hang wet clothes outside, the air helps dry them by
taking away the wetness.
2.
Wind, which is moving air, helps lift kites up into the sky when we
fly them.
3.
Blowing air into soap bubbles with our breath makes them float
and fly around.
4.
Fans and air conditioners use air to cool us down when it's hot. 5.
Balloons get filled with air to make them big and float, which is
so much fun!

FAQs on PPT: Air Around Us - Science for Class 1

1. What is air?
Ans. Air is the invisible mixture of gases that surrounds the Earth. It is primarily composed of nitrogen (about 78%) and oxygen (about 21%), along with small amounts of other gases such as carbon dioxide, argon, and traces of water vapor.
2. How does air move?
Ans. Air moves due to differences in air pressure. When air is heated, it expands and becomes less dense, resulting in lower air pressure. This creates a pressure gradient, causing air to move from areas of high pressure to areas of low pressure. This movement of air is what we perceive as wind.
3. Why is air important for living beings?
Ans. Air is vital for living beings as it provides oxygen for respiration. Oxygen is necessary for the survival of all organisms, including humans. Additionally, air plays a crucial role in regulating temperature, enabling the transport of sound, and dispersing pollutants and odors.
4. What is the role of air in the water cycle?
Ans. Air plays a significant role in the water cycle. When water evaporates from the Earth's surface, it turns into water vapor and rises into the atmosphere. This water vapor condenses to form clouds, and when the conditions are right, it precipitates back to the Earth as rain, snow, or hail. Air currents help in the transportation of water vapor during this process.
5. How does air pollution affect the environment?
Ans. Air pollution has detrimental effects on the environment. It contributes to the depletion of the ozone layer, which protects us from harmful ultraviolet (UV) radiation. Moreover, air pollution leads to the formation of smog, acid rain, and contributes to global warming. It also adversely affects human health, causing respiratory problems, allergies, and other illnesses.
