FAQs on Air and Water Video Lecture - Social Science for Class 1

1. What are the main components of air?

Ans. The main components of air are nitrogen (N₂), which makes up about 78%, and oxygen (O₂), which comprises about 21%. The remaining 1% includes argon (Ar), carbon dioxide (CO₂), and other trace gases. These gases are essential for life, as oxygen is needed for respiration, while carbon dioxide is used by plants for photosynthesis.

2. How does water travel in nature?

Ans. Water travels in nature through the water cycle, which consists of several key processes: evaporation (water turning into vapor), condensation (vapor forming clouds), and precipitation (rain, snow, or hail falling back to the ground). This cycle helps distribute water across the planet, supporting ecosystems and human needs.

3. Why is weather important for our daily lives?

Ans. Weather is crucial for our daily lives as it influences our clothing choices, outdoor activities, and even our mood. Additionally, it affects agriculture, transportation, and energy consumption. Understanding weather patterns helps people prepare for various conditions, ensuring safety and efficiency in daily activities.

4. What is the difference between weather and climate?

Ans. Weather refers to the short-term atmospheric conditions in a specific place at a specific time, including temperature, humidity, precipitation, and wind. Climate, on the other hand, is the average weather patterns observed over a long period, typically 30 years or more, in a particular region. This distinction is important for understanding environmental changes and planning.

5. How do changes in weather affect air quality?

Ans. Changes in weather can significantly impact air quality. For example, high temperatures can lead to the formation of ground-level ozone, while stagnant air can trap pollutants close to the ground. Additionally, rainfall can help clear pollutants from the air, improving air quality. Understanding these interactions is vital for public health and environmental protection.
