Earth’s atmosphere is a layer of gases that surrounds the planet and supports life by regulating temperature and protecting living organisms. It plays a crucial role in weather formation, climate regulation, and the water cycle. Without the atmosphere, life on Earth would not be possible.
Major Functions
- Protects Earth from harmful ultraviolet radiation
- Maintains a stable climate and temperature
- Enables weather and precipitation
- Supports respiration and photosynthesis
Layers of the Atmosphere
- Troposphere – where weather occurs
- Stratosphere – contains the ozone layer
- Mesosphere – burns meteors
- Thermosphere – absorbs high-energy radiation
- Exosphere – outermost layer
Examples
- Rainfall and cloud formation
- Ozone layer protecting life
- Wind and weather patterns
