Hey everyone guess where I am well don't think so hard I am in space do you see 00:00:00
that blue ball well that's where you are that's the earth but hey what are these 00:00:21
they are the layers of atmosphere so let's learn about the layers of 00:00:29
atmosphere today zoom in this is the troposphere this layer is where the 00:00:36
weather occurs this is the lowest atmospheric layer and begins at the 00:00:43
surface of the earth and extends out to about four to ten miles the temperature 00:00:49
the troposphere decreases with increase in altitude just so that you know 00:00:55
altitude is the height of an object or point in relation to the ground level 00:01:02
now we are in the stratosphere second lowest layer of Earth's atmosphere here 00:01:08
the temperature rises with the rise in altitude you will also find the ozone 00:01:16
layer here which helps absorb harmful UV rays from the Sun this is the layer 00:01:22
where you will find aeroplanes flying around as the stratosphere is free of 00:01:32
all weather disturbances the stratosphere extends to about 30 to 35 00:01:37
miles above the Earth's surface this is the mesosphere where most meteors burn 00:01:43
Turn upon entry, the mesosphere stretches up till 50 miles from the earth's surface. 00:01:51
The thermosphere is next and the air is very thin here. 00:01:58
Temperatures get extremely hot in the thermosphere. 00:02:03
It extends up to 400 miles from the earth's surface. 00:02:07
The lower part of this layer contains the ionosphere. 00:02:11
Many atoms are ionized in this layer. 00:02:16
And you will also find electrical charge here. 00:02:18
This is the last layer and the air is quite thin here. 00:02:25
Yes, it is the exosphere. 00:02:29
It goes all the way up to 6200 miles from the earth's surface. 00:02:32
Trivia Time! 00:02:38
Did you know? 00:02:43
Troposphere contains more than 75% of atmosphere's mass. 00:02:45
mass and the ions in the ionosphere help to transmit radio waves it's getting a 00:02:49
bit spooky here I think it's time for me to get back to earth so this is me 00:03:00
zooming out tune in next time for more fun facts 00:03:06
