What is the important of the atmosphere?
The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight (figure below). The atmosphere shields Earth from the most harmful solar rays.
How does atmosphere affect our daily life?
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.
What is the importance of atmosphere Class 9?
It acts as a protective blanket for organisms existing on earth. As air in the atmosphere is bad conductor of heat, it helps to maintain the erth’s temperature by preventing the sudden increase in temperature during day and also during the night, it slows down the escape of heat into the outer space.
What is the importance of presence of greenhouse gases in the atmosphere?
These include water vapor, methane, nitrous oxide, and ozone. Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth’s heat energy so that it doesn’t all escape into space. This heat trapping is known as the greenhouse effect.
How climate affects our life Explain with examples?
The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels. These impacts threaten our health by affecting the food we eat, the water we drink, the air we breathe, and the weather we experience.
What are 5 things the atmosphere does for us?
Terms in this set (5)
- protects us from the sun.
- protects from metors.
- gives us oxygen and protein.
- allows us to stay alive.
Which gas is maximum in atmosphere?
nitrogen
What will happen if the percentage of oxygen and carbon dioxide are reversed?
If the oxygen and carbondioxide concentrations are reversed then humans will not survive. The air we breath in has higher percentage of oxygen and so in lung cells hemoglobin preferentially binds to oxygen releasing carbondioxide which is breathed out.
What percentage of oxygen is dangerous?
19.5 percent
