The<u> troposphere</u> is the lowest layer of our atmosphere.
The next layer up is called the <u>stratosphere. </u>
Above the stratosphere is the <u>mesosphere</u>.
The layer of very rare air above the mesosphere is called the <u>thermosphere.</u>
Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the <u>exosphere </u>to be the actual "final frontier" of Earth's gaseous envelope.
The <u>ionosphere</u> is not a distinct layer like the others mentioned above.
The answer is Satellites because they help with transmitting radio rays so that we can communicate with one another.
