THE LAYERS

As you know from the last post, the atmosphere layers are Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere. 

What is Troposphere? like i said before, troposphere is the lowest layer of the earth's atmosphere. The troposphere contain water vapor. The altitude of the troposphere is 20km. wait..WHAT IS ALTITUDE? altitude is the height of something above the earth surface. so the height of troposphere from the earth surface is 20 kilometers. The temperature of troposphere is 15°C but it can decrease until -55°C.

fun fact: 80% of the atmosphere mass is in the troposphere

The second layer, STRATOSPHERE. the stratosphere contains ozone which reduce the heat of ultraviolet rays*. the temperature of this layer is -3°C. the altitude or the distance of this layer is 50 kilometers.

*ultraviolet ray is a ray from the sun that gives the earth heat. ultraviolet is really hot but because of the atmosphere, the temperature of ultraviolet decrease.

the third layer is the mesosphere. the temperature of this layer is -143°C. the distance of this layer is 85 Kilometers. this layer is the one that holds meteors. each year, millions of meteors come to earth but, it is destroyed by the mesosphere.

the fourth layer is Thermosphere. the thermosphere is really hot. the temperature is 2500°C. the altitude is 600 kilometers.

yeay the last layer! okey so the last layer is the exosphere. the altitude of this layer is 1000 kilometers. this layer is the one with earth's satellites so you can watch your TV. 

and that's it! NOW YOU HAVE KNOW ALL OF THE LAYERS. HAVE FUN!!
