- Protection. The atmosphere blocks out harmful rays from the sun. …
- Water. The Earth's atmosphere contains water. …
- Oxygen and Carbon Dioxide. Life on Earth needs the atmosphere to breath. …
- Other Benefits. The atmosphere contains a large amount of nitrogen.
Why is the atmosphere important to life on earth?
The atmosphere
protects life on earth by shielding it from incoming ultraviolet (UV) radiation
, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
What are 3 facts about the atmosphere?
The atmosphere is made up of
78% nitrogen, 21% oxygen, and smaller amounts of argon, carbon dioxide, helium, and neon
. Contaminants in the atmosphere can include smoke, toxic gasses, dust, ash from volcanoes, and salt.
How is the atmosphere important to us?
It is very essential for life on earth. Complete Answer: The
atmosphere contains the air that we breathe
; protects us from the harmful radiation of the Sun; helps to keep the planet's heat on the surface, and plays a very important role in the water cycle.
What are 5 things the atmosphere does for us?
- protects us from the sun.
- protects from metors.
- gives us oxygen and protein.
- allows us to stay alive.
Why is the atmosphere important for humans?
The atmosphere protects us from UV and other short wavelength light that would otherwise do a lot of damage to the DNA of living organisms. … The atmosphere is also important
because it contains oxygen
, which we and other living organisms breathe.
How do we affect the atmosphere?
Burning fossil fuels, releasing chemicals into the atmosphere
, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
What are the advantages of atmosphere?
The Earth's atmosphere
protects and sustains the planet's inhabitants by providing warmth and absorbing harmful solar rays
. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun's energy and wards off many of the dangers of space.
What is the role of atmosphere?
The atmosphere is
a protective layer that safeguards the earth from the harsh conditions of the solar system
. … During the day, it prevents a sudden increase in the temperature of the earth and prevents the heat to escape to the outer space during the night. It keeps the average temperature of the earth steady.

What is 80% of the atmosphere?
Troposphere
. The troposphere is the atmospheric layer closest to the planet and contains the largest percentage (around 80%) of the mass of the total atmosphere. Temperature and water vapor content in the troposphere decrease rapidly with altitude.
What is the hottest layer of the atmosphere?
The thermosphere
is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 oC in this layer (Wallace and Hobbs 24).
What is the most important function of the atmosphere?
Atmosphere is essential
for life
on Earth as it supplies oxygen, water, CO
2
and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation.
Are we losing our atmosphere?
Around 90 tonnes of the atmosphere disappears into space every day
, according to the European Space Agency. This sounds like a lot, but it's just a tiny part of the atmosphere. “It would probably take more than 150 billion years before the atmosphere disappeared this way,” says Samset.
What are the disadvantages of atmosphere?
- The atmosphere holds in some “greenhouse” gases that retain the heat of the Sun. …
- Clouds regularly obscure good astronomical viewing.
- The atmosphere refracts light which means the position and clarity of star viewing is less accurate.
- Pollution from light and chemicals obscure observations.
How does Earth's atmosphere allow life to exist?
Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. … This mixture of gases is commonly known as air. The atmosphere protects life on Earth by
absorbing ultraviolet solar radiation and reducing temperature extremes between day and night
.
