00:00:00.850 --> 00:00:03.590
This is the Cryosphere

2
00:00:03.590 --> 00:00:05.890
Cryo=Frozen

3
00:00:05.890 --> 00:00:06.400


4
00:00:06.400 --> 00:00:08.200
It has five parts

5
00:00:08.200 --> 00:00:09.010
Sea Ice

6
00:00:09.010 --> 00:00:09.770
Snow

7
00:00:09.770 --> 00:00:10.390
Permafrost

8
00:00:10.390 --> 00:00:11.070
Glaciers

9
00:00:11.070 --> 00:00:12.680
Ice Sheets

10
00:00:12.680 --> 00:00:14.990
That's a lot of ice

11
00:00:14.990 --> 00:00:16.520


12
00:00:16.520 --> 00:00:17.880
The Cryosphere is pretty important

13
00:00:17.880 --> 00:00:21.940
Basically, life on Earth needs it to survive

14
00:00:21.940 --> 00:00:24.690
But parts of it are melting quickly

15
00:00:24.690 --> 00:00:28.370
NASA is working on finding answers

16
00:00:28.370 --> 00:00:32.800


17
00:00:32.800 --> 00:00:35.970
Cryosphere

18
00:00:35.970 --> 00:00:37.680


19
00:00:37.680 --> 00:00:39.706
