FAQs on Air and Atmosphere Video Lecture - Chemistry Class 6 ICSE

1. What is the composition of air?

Ans. Air is a mixture of gases. It is primarily composed of nitrogen (about 78%), oxygen (about 21%), and small amounts of other gases such as carbon dioxide, argon, and water vapor. These gases are essential for life on Earth.

2. Why is the atmosphere important for life on Earth?

Ans. The atmosphere is crucial for life as it provides oxygen for breathing, protects living organisms from harmful solar radiation, and helps regulate the Earth's temperature. It also plays a role in weather patterns and the water cycle.

3. What are the different layers of the atmosphere?

Ans. The atmosphere is divided into several layers based on temperature changes. These layers are: 1. Troposphere – where we live and where weather occurs. 2. Stratosphere – contains the ozone layer, which protects us from UV radiation. 3. Mesosphere – where meteors burn up. 4. Thermosphere – contains the ionosphere, where auroras occur. 5. Exosphere – the outermost layer, where satellites orbit.

4. How does air pollution affect the atmosphere?

Ans. Air pollution occurs when harmful substances are released into the atmosphere, often from vehicles, industries, and burning of fossil fuels. This can lead to health problems, climate change, and damage to the ozone layer, affecting both the environment and human health.

5. What is the greenhouse effect and its significance?

Ans. The greenhouse effect is a natural process where certain gases in the atmosphere trap heat from the sun, keeping the Earth warm enough to support life. However, human activities have increased the concentration of these greenhouse gases, leading to global warming and climate change, which poses significant risks to ecosystems and human society.
