4. Atmosphere
The atmosphere is a vital layer of gases that supports life on Earth by providing oxygen, regulating temperature, and safeguarding against harmful solar radiation. Understanding its composition, structure, and function is imperative for addressing significant environmental challenges, such as pollution and climate change. The intricate balance maintained by the atmosphere is influenced by both natural phenomena and human activities.

What we have learnt
- The atmosphere is crucial for the survival of life on Earth as it provides necessary gases and regulates temperature.
- The structure of the atmosphere is divided into distinct layers, each with unique characteristics and functions.
- Human impact on the atmosphere, including air pollution and greenhouse gas emissions, significantly affects climate patterns and environmental health.
Key Concepts
- -- Atmosphere
- A layer of gases surrounding the Earth, essential for sustaining life by providing oxygen and regulating temperature.
- -- Troposphere
- The lowest layer of the atmosphere where weather occurs and which contains most of its mass.
- -- Greenhouse Effect
- A natural process by which certain gases trap heat in the atmosphere, keeping the Earth's surface warm enough to support life.
- -- Climate Change
- Long-term changes in temperature and weather patterns often linked to human activities that increase greenhouse gas concentrations.
- -- Ozone Layer
- A region within the stratosphere that absorbs most of the Sun's harmful ultraviolet radiation.
