What is the importance of the atmosphere essay?
It acts like a greenhouse and keeps the average temperature of the earth around 35°C and also protects the earth from the harmful radiation of the sun. The atmosphere is a storehouse for water vapour and serves as the medium of faster air transport.
What is the importance of 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.
What is atmosphere in simple words?
The atmosphere is the layer of gases around the Earth. It is held in place by Earth’s gravity. It also has plentiful oxygen (20.9%) and small amounts of argon (0.9%), carbon dioxide (~ 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing (taking) ultraviolet rays from the sun.

What is structure of atmosphere?
The atmosphere consists of 4 layers: the troposphere, stratosphere, mesosphere, and thermosphere. The boundary between the stratosphere and the troposphere is called the tropopause. The jet stream sits at this level and it marks the highest point that weather can occur.
What is atmosphere and structure of atmosphere?
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth’s surface is called the exosphere.
Why is the atmosphere important for humans?
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 height does the atmosphere end?
But the atmosphere doesn’t stop there — it continues on, gradually thinning out for thousands of miles. The final layer of the atmosphere, the enormous exosphere, continues until around 6,700 miles (10,000 km) above the surface of our planet (and some say even further).
How much carbon dioxide is in the atmosphere?
The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.
What is the hottest layer of the atmosphere?
thermosphere
What are some examples of atmosphere?
Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.
What is the first layer of the atmosphere?
troposphere
What is another word for the atmosphere?
aerosphere
What is the opposite of atmosphere?
The opposite of having an atmosphere is simply not having one. This could also be described as “vacuum”: That moon has no atmosphere. In short, “vacuum” could be used as an antonym given the appropriate context and usage but it only truly relates to the air/environment surrounding a celestial body.
How do you describe mood and atmosphere?
In literature, mood is the feeling created in the reader. This feeling is the result of both the tone and atmosphere of the story. Atmosphere is the feeling created by mood and tone. The atmosphere takes the reader to where the story is happening and lets them experience it much like the characters.

Why is it important to understand the milieu of the story?
Setting is the context in which a story or scene occurs and includes the time, place, and social environment. It is important to establish a setting in your story, so your readers can visualize and experience it. If your readers don’t know where or when the action is unfolding, they will be lost.
What is the importance of each layer of the atmosphere?
Earth’s atmosphere is similar to a jacket for our planet. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Earth’s atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere.
What do humans do to affect the atmosphere?
There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth’s atmosphere, ocean and land surface to increase …
Why is atmosphere essential for life in points?
Answer: Atmosphere is very important for sustaining life: It contains various gases like O2, CO2, N2 which are required for various life processes by plants and animals. (ii) gas is used by plants to prepare food by the process called photosynthesis (iii) Oxygen is required for burning, combustion and respiration.
What is the important of atmosphere?
What would happen if we had no atmosphere?
Eventually (long after surface life had died), solar radiation would break atmospheric water into oxygen, which would react with carbon on the Earth to form carbon dioxide. The air would still be too thin to breathe. The lack of atmosphere would chill the Earth’s surface. Plants and land animals would die.
What are the important gases of the atmosphere?
The permanent gases whose percentages do not change from day to day are nitrogen, oxygen and argon. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.
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.
Why is nitrogen the most abundant gas in the atmosphere?
Compared to O, N is 4 times as abundant in the atmosphere. This is one reason why nitrogen is so enriched in the atmosphere relative to oxygen. The other primary reason is that, unlike oxygen, nitrogen is very stable in the atmosphere and is not involved to a great extent in chemical reactions that occur there.
