Clouds are an important part of the water cycle. Clouds are how liquid water moves through the atmosphere. This blog post will teach you all about how clouds form, the different types of clouds, and how clouds affect the Earth.
If you would like to get the bundle of atmosphere-related reading passages, picture books, flashcards, and comprehension activities, you can find it at Teachers Pay Teachers.
An Introduction to the Atmosphere
The atmosphere is the layer of gases that surrounds Earth. It is essential for life, providing the air we breathe and protecting us from harmful space radiation and extreme temperatures. The atmosphere also helps control Earth's climate and weather.
Layers of the Atmosphere
Earth’s atmosphere is divided into five main layers:
Troposphere – This is the lowest layer, where we live and where weather happens. It contains most of the air and clouds.
Stratosphere – This layer contains the ozone layer, which absorbs harmful ultraviolet (UV) radiation from the Sun.
Mesosphere – This is the coldest layer, where most meteors burn up before reaching Earth’s surface.
Thermosphere – This layer is very thin but can get extremely hot. The auroras (Northern and Southern Lights) occur here.
Exosphere – The outermost layer, where Earth's atmosphere fades into space.
What is the Atmosphere Made of?
The atmosphere is mostly made of nitrogen (78%) and oxygen (21%), with small amounts of other gases like carbon dioxide, argon, and water vapor. These gases are crucial for life, weather, and climate.
Why is the Atmosphere Important?
Protects life by blocking harmful solar radiation.
Provides oxygen for animals and carbon dioxide for plants.
Regulates temperature by trapping heat (the greenhouse effect).
Allows weather to occur, bringing rain, wind, and storms.
Without the atmosphere, Earth would be a lifeless, frozen rock in space. It is truly our planet’s protective shield!
