FAQs on Flashcards: Atmosphere and Weather Video Lecture - Science for Class 4

1. What is the difference between weather and climate?
Ans. Weather refers to the short-term atmospheric conditions in a specific area, such as temperature, humidity, and precipitation, while climate refers to the long-term patterns of weather in a particular region over a period of time.
2. How does the atmosphere affect weather patterns?
Ans. The atmosphere plays a crucial role in shaping weather patterns by controlling the temperature, moisture levels, and air pressure in different regions. These factors interact to create weather phenomena such as rain, storms, and winds.
3. What are the different layers of the atmosphere and their characteristics?
Ans. The Earth's atmosphere is divided into five main layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique characteristics such as temperature changes, air composition, and altitude.
4. How do greenhouse gases contribute to climate change?
Ans. Greenhouse gases trap heat in the Earth's atmosphere, leading to an increase in global temperatures. This phenomenon, known as the greenhouse effect, is primarily caused by human activities such as burning fossil fuels and deforestation.
5. How do meteorologists predict the weather?
Ans. Meteorologists use various tools and technologies, such as satellites, radar systems, and computer models, to analyze atmospheric data and make informed predictions about future weather conditions. These forecasts help people prepare for potential storms, heatwaves, or other weather events.
