Dr. Binocs! Dr. Binocs! Oh, hello friends! The best part of a pizza is its crust.

2
00:00:15,689 --> 00:00:25,690
Mmm, yummy! Just like this pizza, the earth too has a crust, but with no cheese in it.

3
00:00:25,690 --> 00:00:30,690
So, let's learn something about the structure of the earth today.

4
00:00:31,690 --> 00:00:34,689
It consists of the crust, mantle and core.

5
00:00:35,689 --> 00:00:36,689
Zoom in!

6
00:00:37,689 --> 00:00:39,689
This is the earth's crust.

7
00:00:40,689 --> 00:00:46,689
It consists of all kinds of rocks, soil and everything you see above the earth's surface.

8
00:00:47,689 --> 00:00:52,689
You will be surprised to know that the crust, that is the land on which we walk..

9
00:00:52,689 --> 00:01:00,369
is almost three times thicker than the crust under the oceans and it extends to

10
00:01:00,369 --> 00:01:08,969
about 25 miles the earth's crust floats on this layer which is called the mantle

11
00:01:08,969 --> 00:01:15,790
it is made of thick solid rocky substance and amounts to about 85% of

12
00:01:15,790 --> 00:01:22,689
the total mass of earth the first 50 miles of the mantle consists of very

13
00:01:22,689 --> 00:01:28,969
hard rigid rocks the next hundred and fifty miles are made up of super hot

14
00:01:28,969 --> 00:01:35,230
solid rocks below that for the next several hundred miles the Earth's mantle

15
00:01:35,230 --> 00:01:42,790
is believed to be made up of very solid and sturdy rock materials the mantle is

16
00:01:42,790 --> 00:01:49,290
is about 1,800 miles thick and by far the largest layer of earth.

17
00:01:50,989 --> 00:01:57,290
The earth's outer core is made up of super hot liquid molten substance called lava.

18
00:02:00,790 --> 00:02:04,489
This lava is believed to be made of iron and nickel.

19
00:02:05,290 --> 00:02:10,590
It extends to a depth of 3,000 miles beneath the earth's surface.

20
00:02:10,590 --> 00:02:20,490
and finally we have reached Earth's inner core the inner core extends another 900

21
00:02:20,490 --> 00:02:26,909
miles towards the center of the earth it is believed that this inner core is a

22
00:02:26,909 --> 00:02:36,469
solid ball made of iron and nickel the crust occupies less than 1% of Earth's

23
00:02:36,469 --> 00:02:43,189
volume the inner coal is the hottest part of the earth and it is as hot as

24
00:02:43,189 --> 00:02:50,289
the surface of the Sun surprising isn't it looks like it's time for me to zoom

25
00:02:50,289 --> 00:02:58,030
out before I get baked in this heat tune in next time for more fun facts
