In this book we will go on a journey into the atmosphere layers.Atmosphere layers are five.Troposphere,Stratosphere,Mesosphere, Thermosphere and Exosphere.

We're now in Troposphere. the Troposphere is the lowest layer in the atmosphere layers where almost all weather conditions occur. The Troposphere contains the things we can see every day in sky like clouds and planes.The Troposphere is from 7km to 20km according to place and temperature.It's 7km in the poles and 10km in the normal places and 20km in the equator.The temperature decreases whenever the height above the ground increases at a constant rate, which is one degree per 150 meters.This layer contains most of the water vapor, oxygen, and carbon dioxide.The temperature in this layer decreases as we go to one of the poles and increases in the equator.

We are go up.Now we are in Stratosphere.It is one of the upper layers of the atmosphere that is above Troposphere and extends from an altitude of 7to20km to about 50km.But now we can't see clouds because in this layer there is no water vapor.Ozone gas is spread near a height of 30 meters, causing an increase in temperature, where it reaches about 95 degrees it's too hot.The temperature changes unlike the Troposphere, so the temperature increases towards the poles and decreases towards the equator.Ozone layer protect the earth from the The sun's harmful rays.

Meteors

Now it's too cold.We will complete the journey in the rocket.It's Mesosphere the coldest layer in the atmosphere layers.Its temperature can reach -100 ° C (minus zero).Most falling meteors and meteorites falling to the surface of the Earth burn in this layer. The great expansion of the atmosphere into space helps burn millions of meteors and protect life on Earth.The noctilucent clouds (clouds seen in the night)is in the Mesosphere.
