One of the most important things for a living is air and atmosphere because without it we can’t breathe.
Earth’s atmosphere is so much more than the air that we breathe.
There are tons of facts about the earth’s atmosphere.
But, here I will not talk about tons of facts but some 16 interesting facts about earth’s atmosphere.
Hey before going on it let’s read 5 facts about the 5 layers of the atmosphere.
5 facts about 5 layers (Layers of our atmosphere) 5️⃣
Earth’s atmosphere stretches from up to as far as 10,000 kilometers (6,214 miles) above the earth surface.
Maybe you are thinking -What are these layers of the atmosphere?
The atmosphere is divided into five different layers.
The troposphere: The layer contains most of the mass.
Layer closest to earth or in which we are breathing.
It reaches about seven and 15 kilometers (five to 10 miles) from the surface.
The majority of the mass of the entire atmosphere is contained in the troposphere- that is approximately 75 to 80 per cent.
Most of the water vapor in the atmosphere, along with dust and ash particles, are found in the troposphere.
In the troposphere, temperatures decrease with altitude. It is thickest near the equator, and much thinner at the North and South Poles.
The stratosphere: Layer of ozone.
The next layer up from Earth’s surface in the stratosphere.
It reaches from the top of the troposphere to an altitude of 50 kilometers (30 miles).
In it, temperature increases with altitude.
Ozone lies in the stratosphere (a molecule composed of three atoms of oxygen) it saves us from dangerous ultraviolet rays.

Mesosphere: the meteor burner.
The next layer is the mesosphere, which reaches as far as about 85 kilometers (53 miles) above Earth’s surface.
The atmosphere is quite thin here, but still thick enough so that meteors will burn up as they pass through it.
The thermosphere: a layer of temperature 2000°c.
The thermosphere is located above the mesosphere and reaches out to around 600 kilometers (372 miles).
Solar radiation makes the upper regions of the thermosphere too hot, temperatures can reach there as high as 2,000°C (3,600°F).
Exosphere: layer closest to outer space.
Last but not the least- exosphere.
Here The pull of Earth’s gravity is so small that molecules of gas escape into outer space.
The exosphere is the last layer, and it widely contains particles of hydrogen and helium.
Facts about earth’s atmosphere
1. Without atmosphere earth would be like moon.
Why the atmosphere is important? This question that’s answer we already know.
As you know that we can not live without air.
And this proves that If the atmosphere did not exist on earth then life could not be sustained on the planet.
Without the atmosphere, the earth would be either too hot or too cold and there would be no rain. And then the earth would be similar to the moon.
And that makes the atmosphere very important for us.
2.Secret behind: Why Earth Appears Blue from space?🤔
Sunlight is scattered in every direction by all the gases present in the atmosphere.
As we know that shorter wavelengths will be scattered much more than longer wavelengths.
Since blue light has very short wavelengths and that’s why it scattered more than any other color.
This is what gives Earth a blue halo when seen from space at a height of 402 to 424 km.
3.Composition of Earth atmosphere.
The Earth’s Atmosphere is nearly 480 km thick, and it is made of a mixture of some about 16 gases:
As we know oxygen is necessary for most life on Earth but the majority of Earth’s atmosphere is not oxygen but it is nitrogen.
Earth’s atmosphere is composed of 78% nitrogen, 21 oxygen, 0.9 per cent argon, and 0.1 per cent other gases.
Trace amounts of glasses like carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the other remaining 0.1 per cent.
4. Is space very far? No
When we think about space we think that it is very far but-
The Karman line is located just around 62 miles above the land and this length is the accepted starting point of space.
it feels very crazy but it’s true and most of you have traveled more distance than this.
5.5 Facts about the global warming
Global warming is the increase of Earth’s temperature due to greenhouse gases in the atmosphere.
Like carbon dioxide, which traps the sun’s heat and causing the planet to warm up.
According to scientists, in the 21st-century global warming is a major problem. So, lets us know some facts about the global warming
1.There is more carbon dioxide in the atmosphere today than at any single point in the last 800,000 years.
2. Since 1870, global sea levels have risen by nearly about 8 inches that is quite much.
3. Only 4 per cent of the world’s population produce 25% of the carbon dioxide pollution from fossil fuel burning. This 4% includes some rich persons.
4. Both Greenland and Antarctica’s ice sheets have decreased in masses.
Data from NASA shows that Antarctica has lost about 148 billion tons of ice per year just because of global warming.
5. We increased it so much. But, once it was much higher in the earth’s history at some points that earth was also like Venus.

6.75% weight is in the troposphere
As we know contaminants in the atmosphere can include smoke, toxic gasses, and dust and ash from volcanoes.
And one of the facts about the atmosphere is that roughly 75% of the weight of the atmosphere is located in the troposphere.
7.Meteors are not a big deal for our Atmosphere.
Every day many meteors enter our atmosphere.
But they get burned up in Earth’s coldest atmosphere layer – the mesosphere
As a meteor starts entering this layer, it quickly burns.
And since the meteor’s speed is high, it quickly generates a quite large amount of heat due to high friction.
So at least for this point, it becomes important to share it on Twitter and show your thanks for our atmosphere.
Thanks for atmosphere – #meteor burner.
8.Ionosphere: the radio layer.
The ionosphere is a region of the upper atmosphere from 70 km to 1000 km altitude.
Maybe you are thinking 💭 what is this radio and why I am saying this?
Ok, I am answering-
It plays a crucial role in radio signal propagation and global positioning system signals around the Earth.
9.How was the ancient atmosphere?
Today if we see the composition of the atmosphere it consists of 78% nitrogen, 21% oxygen and various other elements and compounds, including varying amounts of water vapor.
But do you ever wondered- what was earth’s early atmosphere like?
However, when our planet was very young, the air was just a product of the solar nebula that gave birth to the planets over 4.5 billion years ago.
If we see, the first atmosphere was formed by volcanic eruptions.
A combination of volcanic outgassing and impact events replaced the predominantly hydrogen atmosphere with nitrogen and carbon dioxide.
10. Earth has the Strongest Magnetosphere.
Earth’s magnetic field reaches nearly 58,000 km into space and this region is called Magnetosphere.
It saves us from most of the particles from the Sun, carried in the solar wind, from hitting the Earth.
11.This light atmosphere has a huge amount of water.💧
Earth’s atmosphere nearly carries 37.5 million billion gallons of water at any specific moment.
All this water — present in the form of vapor and it is enough to cover the whole surface of the Earth with 2.5 cm of rain.
Every year, this amount of water is recycled 40 times.
If you like the maths, then each water vapor molecule spends only 9 days in the atmosphere.
12.Layer that protects us like a shield🛡️
When we think of shields, Captain America may come to our minds.
But there is also one shield that saves us from dangerous ultraviolet rays and that is ozone.
One the of most essential things in the atmosphere of the Earth is the Ozone layer so let’s know 5 facts about the ozone layer:
1. It is just 19-32 km above the Earth’s surface. It’s a blue gas that simply absorbs most of the sun’s ultraviolet radiation.
2. If ozone is not there then life can never be possible. It protects us from ultraviolet sun rays that may also cause lung cancer.
3. In 1985, a big hole in the ozone layer was discovered above the Antarctic.
4.The situation has much improved following the ban of Chlorofluorocarbons.
5. Just one atom of chlorine can destroy more than a hundred thousand ozone molecules.
13. The atmosphere is leaking 90 tons every day.
You may believe or but it is true that
Earth is losing its atmosphere continuously.
Every single day, approx. 90 tonnes of material escapes from our upper atmosphere and streams out into space.
But don’t worry 90 tonnes per day is a tiny leak.
Because our atmosphere weighs 5 quadrillion tonnes, so we are not in danger of running out of the atmosphere.
14.Why Does Sunset Appear Red?🌇
It is so romantic to see the sunset but do you ever wonder why is it red?
At sunset, most of the rays of the light are reflected and scattered in the atmosphere and the Sun appears dimmer.
The color of the Sun itself appears to alter, first to orange and then to red.
This happens because the shorter wavelengths (green and blue) scatter more, leaving only the longer wavelengths (red and orange) to be seen. That’s why the sunset appears red.
15.Does Lightning cause heat?
This may look like a joke but it is true.
Even only a single stroke of a lightning bolt can heat the surrounding air to 27,000 degrees Celsius.
Since it travels at an extremely fast speed, the heated air has no time to expand.
16.Increase of oxygen From 1 per cent to 21. 📈
Did you 2.4 billion years ago there was very little oxygen while carbon dioxide was in majority?
But, some common green algae was responsible for the first major extinction event.
Look here there was most of the part of the atmosphere as carbon dioxide but these small algae have created oxygen through photosynthesis.
They have made the earth possible for living. They must deserve one share. So, share it and show your intelligence.
