You
00:00:00
Hey everyone guess where I am
00:00:11
Well, don't think so hard. I am in space
00:00:15
Do you see that blue ball?
00:00:20
Well, that's where you are
00:00:22
That's the earth
00:00:25
But hey, what are these? They are the layers of atmosphere
00:00:27
So, let's learn about the layers of atmosphere today.
00:00:33
Zoom in!
00:00:37
This is the Troposphere.
00:00:39
This layer is where the weather occurs.
00:00:41
This is the lowest atmospheric layer and begins at the surface of the earth..
00:00:44
..and extends out to about 4 to 10 miles.
00:00:51
The temperature of the Troposphere decreases with increase in altitude.
00:00:54
Just so that you know, altitude is the height of an object or point in relation to the ground level.
00:00:59
Now we are in the stratosphere, second lowest layer of earth's atmosphere.
00:01:08
Here the temperature rises with the rise in altitude.
00:01:15
You will also find the ozone layer here, which helps absorb harmful UV rays from the sun.
00:01:20
This is the layer where you will find aeroplanes flying around.
00:01:27
As the stratosphere is free of all weather disturbances.
00:01:35
The stratosphere extends to about 30 to 35 miles above the earth's surface.
00:01:39
This is the mesosphere, where most meteors burn upon entry.
00:01:46
The mesosphere stretches up till 50 miles from the earth's surface.
00:01:52
The thermosphere is next and the air is very thin here.
00:01:56
Temperatures get extremely hot in the thermosphere.
00:02:02
It extends up to 400 miles from the earth's surface.
00:02:06
The lower part of this layer contains the ionosphere.
00:02:11
Many atoms are ionized in this layer and you will also find electrical charge here.
00:02:15
This is the last layer and the air is quite thin here.
00:02:21
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
Did you know?
00:02:43
Troposphere contains more than 75% of atmosphere's mass.
00:02:44
And the ions in the ionosphere help to transmit radio waves.
00:02:50
It's getting a bit spooky here.
00:02:59
I think it's time for me to get back to earth.
00:03:02
So this is me zooming out.
00:03:05
Tune in next time for more fun facts.
