Reveal answer ↓
What it is
The atmosphere is Earth's protective blanket of air that supplies gases and steadies temperature.
Answer
The atmosphere is a blanket of air that supports life in several ways: it provides oxygen for breathing and carbon dioxide for photosynthesis, keeps the temperature of the Earth steady by preventing sudden day-to-night changes, and shields us from the Sun's harmful ultraviolet rays through the ozone layer. Winds and the water cycle also depend on it.
- •Provides oxygen and carbon dioxide
- •Keeps temperature steady (day and night)
- •Ozone layer blocks harmful UV rays
- •Drives winds and the water cycle
Why learn this
It gives us oxygen, blocks harmful UV rays (ozone) and drives weather - no atmosphere, no life.
💡 Memory trick
The air blanket does 3 B's: Breathe, Block UV, Balance temperature.
