Gazing up at the sky has always been a favorite pastime of mine – from admiring fluffy white clouds to watching thunderstorms roll in. But have you ever stopped to think about what makes up our earth’s atmosphere? It’s a complex and fascinating topic that many of us take for granted every day.

Earth’s atmosphere is made up of several layers, each with its own unique properties. From the glistening auroras in the mesosphere to the protective ozone layer in the stratosphere, there are countless wonders to explore within our planet’s expansive skies.

In this article, we’ll delve into Earth’s atmospheric composition and unravel its intricacies so that even non-scientists can appreciate just how incredible it truly is! So sit back, relax, and get ready for an adventure through one of nature’s most awe-inspiring creations: The Earth Atmosphere.

What is the different atmospheres on the earth?

The Earth’s atmosphere is made up of several layers. The lowest layer, which is closest to the ground, is called the troposphere. This layer contains most of the air we breathe and extends up to about 10 kilometers (6 miles) above sea level.

Above the troposphere lies the stratosphere, which extends from 10 to 50 kilometers (31 miles) above sea level. This layer contains a lot of ozone, which absorbs harmful UV radiation from the sun.

Beyond the stratosphere lies the mesosphere, which extends up to about 85 kilometers (53 miles) above sea level. Temperatures in this layer can drop as low as -100 degrees Celsius (-148 degrees Fahrenheit).

Finally, there’s the thermosphere, which extends beyond 600 kilometers (372 miles) above sea level. In this part of the atmosphere, temperatures can reach thousands of degrees Celsius due to interactions with solar radiation.

Overall, each atmospheric layer plays an important role in regulating temperature and protecting life on Earth from harmful solar radiation.

What are the different temperatures on each of the atmospheres?

The Earth’s atmosphere is composed of several layers, each with different temperatures. The lowest layer is the troposphere, where most weather occurs and where we live. The temperature in the troposphere decreases as altitude increases, by about 6.5°C per kilometer.

Above the troposphere is the stratosphere, which contains the ozone layer that protects us from harmful UV radiation. The temperature in this layer increases with altitude due to the absorption of UV radiation by ozone molecules.

Next up is the mesosphere, where temperatures drop rapidly to around -90°C at its upper boundary (known as the mesopause). This layer absorbs meteors and other debris from space before they can reach Earth.

Finally, there is the thermosphere which has a relatively high temperature despite being far above Earth’s surface because it absorbs extreme ultraviolet radiation from the Sun. However, since this region has a very low density of particles and molecules present (almost like a vacuum), it wouldn’t feel hot if you were there!

Transition: Now that we know about different atmospheric layers on Earth let’s discuss what makes them so unique!
