Prayer:
Dear Lord and Father of all, Thank you for today. Thank you for ways in which you provide for us all. For Your protection and love we thank you. Help us to focus our hearts and minds now on what we are about to learn. Inspire us by Your Holy Spirit as we listen and write. Guide us by your eternal light as we discover more about the world around us. We ask all this in the name of Jesus. Amen.

Layers of the Atmosphere:
Troposphere-This is the first and the lowest layer of Earth’s atmosphere. All life on this planet is affected by the changes that happen in this layer, as all the weather changes take place in troposphere. It starts from the ground (or sea level) of our planet and expands up to 10 km up in the sky.
16
Layers of the Atmosphere:
If we start from the top of the troposphere and go further into the sky, we reach the layer known as the stratosphere. This layer goes up around 50 km above the Earth’s ground. In this layer, the temperature rises as you go further up, and it has something to do with the ozone layer that is found inside the stratosphere. ozone layer serves a vital role in the protection of our planet, as the molecules of ozone prevent ultraviolet light from the Sun to hit our planet without stopping. The UV light is not technically stopped, but the conversion from UV light to heat happens (which is why holes in the ozone layer are so dangerous).

Layers of the Atmosphere
The mesosphere goes up to 85 km above the surface of our planet, and the temperatures here behave as they do in the troposphere. In essence, the higher you go, the colder it gets. The air in this layer is absolutely not friendly for us, as it would be impossible to breathe in the mesosphere because of too low oxygen levels. Also, this layer of the atmosphere has the lowest temperature of all layers, and they drop down to -90° C.

Layers of the Atomsphere
The thermosphere -The layer that is located between 500 and 1000 km above the Earth’s level is known as the thermosphere. You have guessed it, high temperatures are the name of the game here. This layer is under constant attack from the X-rays and UV radiation coming from the Sun and the space around us. Because of this, the temperatures in this layer can even reach 2,000° C.

Layers of the Atmosphere
The exosphere Unlike other layers, which are mostly distinguishable from one another, it is hard to say how far the exosphere is from the surface of the planet. Somewhere it is around 100,000 km, but it can expand up to 190,000 km above sea level. The air here is extremely thin, and the conditions here are more similar to the ones we find when we leave the Earth’s atmosphere entirely.
