How does Earth's atmosphere make conditions on Earth suitable for living things?
Answer (3)
Earths atmosphere makes conditions on Earth suitable for living things because it contains oxygen and other gases that you and other living things need to live.
Earth's atmosphere has mainly** five layers** as **exosphere, thermosphere, mesosphere, stratosphere and troposphere. **The composition of atmosphere is 78 % of N₂, 21 % of O₂, 1 % of Ar and rest is CO₂ and trace gases. Earth's atmosphere helps to make suitable conditions for living things by
1. blocking harmful uv rays by ozone layer **
2. trapping heat to maintain the temperature on Earth's surface** **
3. having O₂ gas for breathing of living things** **
4. having CO₂ gas which is used to make foods by photosynthesis** **
5. creating pressure on Earth's surface to keep water in its liquid form.**
The Earth's atmosphere enables life by supplying essential gases like oxygen and carbon dioxide, protecting against harmful UV rays, and regulating temperature. It also plays a crucial role in the water cycle and maintaining liquid water. This combination of factors creates a stable and suitable environment for living organisms.
