2. 0:12hello it's paxi your favorite space
3. 0:16Explorer I'm trying a new fun activity
4. 0:19today ice skating did you know that I'm
5. 0:23skating on Frozen
6. 0:25water water is very special in its
7. 0:29liquid form you can drink it in its gas
8. 0:33form it's vapor in the air in its solid
9. 0:36state it's ice that we can skate on did
10. 0:40you know the Earth's poles help cool
11. 0:42down the planet that's because most of
12. 0:45the ice on Earth is found in the polar
13. 0:47regions known as Earth's refrigerators
14. 0:51let's explore ice in these areas let's
15. 0:55travel to the Arctic Circle the area
16. 0:58around the North Pole
17. 1:00here there is an ocean capped with
18. 1:03floating sea ice which forms as the
19. 1:06seawater freezes during the very cold
20. 1:10Winters without sea ice the oceans would
21. 1:13absorb the sun's heat making the earth a
22. 1:16much warmer Planet sea ice helps prevent
23. 1:20this by bouncing sunlight back to
24. 1:23space polar bears love sea ice because
25. 1:26it helps them find food
26. 1:30let's travel to Antarctica the continent
27. 1:33at the South
28. 1:35Pole Antarctica is one large sheet of
29. 1:38ice formed by snow piling up over
30. 1:41thousands of years on land 90% of
31. 1:45Earth's land ice is in Antarctica
32. 1:48Antarctica is a cool place to live but
33. 1:51mostly for
34. 1:53Penguins it's so cold that only a few
35. 1:57humans can live here in special research
36. 2:00bases for a short period of
37. 2:02time places like this are very important
38. 2:06for the planet when the sun shines here
39. 2:10the ice bounces the sunlight back to
40. 2:12space helping Earth
41. 2:15cool there is so much ice on Earth how
42. 2:19can we know how much there
43. 2:22is scientists monitor the amount of ice
44. 2:26in the world using tools such as
45. 2:28satellites
46. 2:30the European Space Agency satellite that
47. 2:32monitors ice is called
48. 2:35cryosat scientists are watching the
49. 2:37amount of ice on Earth decrease every
50. 2:39year and that is because our planet is
51. 2:43getting warmer melting ice causes water
52. 2:46levels in the ocean to rise which leads
53. 2:49to flooding and loss of habitat for
54. 2:52animals and humans all around the
55. 2:57world Ice is very important important to
56. 3:00earth's climate the more we know about
57. 3:03changes in ice the quicker we can take
58. 3:06steps to protect our planet and keep on
59. 3:10enjoying ice today we learned ice is
60. 3:15frozen water and could be found on land
61. 3:18and at Sea when and where it is cold sea
62. 3:22ice forms when sea water freezes during
63. 3:25the very cold
64. 3:27Winters ice helps the earth cool by
65. 3:30reflecting heat from the Sun back into
66. 3:34space scientists use satellites to study
67. 3:37ice melting and the impact it has on our
68. 3:41planet most land ice is found in
69. 3:46Antarctica see you soon to show you more
70. 3:50incredible things about your planet and
71. 3:53the universe
