The Atmosphere Rules!

          The atmosphere has different layers. All of them are interesting and have different jobs of protecting our planet Earth. The main layers from top to bottom are: Troposphere, Strat0sphere, Mesosphere, and Thermosphere. The other layers are Ozonosphere, Ionosphere, Exosphere, and Magnetosphere. We live in the Troposphere. The Stratosphere contains most of the atmosphere’s ozone and airplanes fly in that layer. The Mesosphere is the coldest layer of the atmosphere and it is the layer where the meteors burn up. The Thermosphere is the layer that astronauts in the ISS orbits at 300 km. Air molecules can be up to 1km apart. The Ozonosphere protects us from the sun’s UV rays. To be a little more technical, it lets in all the UVC rays in, it protects us from some UVB rays, and it protects us from all of the UVA rays.  The Ionosphere helps bounce radio waves back to Earth and it is where the Aurora happens.  The Exosphere is where satellites orbit and there is no technical “end”. The Magnetosphere is our magnetic field, and without it, our atmosphere would blow away. Scientists think that Mars used to have an atmosphere, but it blew away over time.
