They are the layers of Atmosphere. So let's learn about the layers of atmosphere today! Zooom in. This is the Troposphere. This layer is where the weather occurs. This is the lowest atmospheric layer and begins at the surface of the earth and extends out to about 4-10 miles The temperature of the troposphere decreases with increase in altitude. Just so that you know, altitude is the height of an object or point in relation to the ground level. Now we're in the Stratosphere. Second lowest layer of Earth's atmosphere. Here, the temperature rises with the rise in altitude. You will also find the Ozone Layer here, which helps absorb harmful UV rays from the Sun. This is the layer where you will find aeroplanes flying around as the Stratosphere is free of all weather disturbances. The stratosphere extends to about 30-35 miles above the Earth's surface. This is the Mesosphere, where most meteors burn upon entry. The Mesosphere streches up till 50 miles from the earth's surface! The Thermosphere is next and the air is very thin here. Temperatures get extremely hot in the Thermosphere. It extends upto 400 miles from the Earth's surface. The lower part of this layer contains the Ionosphere. Many atoms are ionized in this layer and you will also find electrical charge here. This is the last layer and the air is quite thin here. Yes, it is the Exosphere. It goes all the way up to 6200 miles from the Earth's surface. TRIVIA TIME! Did you know? Troposphere contains more than 75% of atmosphere's mass. And the Ions in the Ionosphere help to transmit Radio Waves! Ooooh.. It's getting a bit spooky here. I think it's time for me to get back to Earth. So, this is me Zooming out! Tune in next time for more fun facts.
