1
00:00:01,260 --> 00:00:06,440
Hi, everybody. We are going to correct the exercises, the social science exercises, okay?

2
00:00:06,660 --> 00:00:17,039
So we have exercises 3, 4, and 5 on page 7, and then we have exercise 3 from page 11, okay?

3
00:00:17,559 --> 00:00:23,079
So first of all, here we have to see if they are correct or false, okay?

4
00:00:23,559 --> 00:00:26,300
And we have to correct the full sentences.

5
00:00:26,920 --> 00:00:32,240
So the first one says meridians are horizontal lines and parallels are vertical lines.

6
00:00:32,619 --> 00:00:39,579
So this one, it is false because meridians are vertical, all these ones, okay,

7
00:00:39,679 --> 00:00:42,240
and the one that is in the middle is the Greenwich meridian,

8
00:00:42,820 --> 00:00:45,880
and then the parallels are horizontal lines, okay,

9
00:00:45,880 --> 00:00:48,899
and the one in the middle, it is the equator, okay?

10
00:00:49,060 --> 00:00:50,579
So this one, it is false.

11
00:00:51,259 --> 00:00:53,340
Okay, next one, the equator is a parallel.

12
00:00:53,899 --> 00:00:55,039
That is correct, okay?

13
00:00:55,060 --> 00:00:55,659
That is true.

14
00:00:56,299 --> 00:00:59,280
And it is the parallel zero, okay?

15
00:01:00,179 --> 00:01:08,599
Then C, meridians are measured in degrees, north or south, and parallels are measured in degrees, east or west.

16
00:01:08,859 --> 00:01:12,180
And this one, it is false because it is the opposite, okay?

17
00:01:12,640 --> 00:01:18,480
Meridians are measured in degrees, east and west, because it goes from here to there, okay?

18
00:01:18,900 --> 00:01:24,920
And parallels are measured in degrees, north and south, because it comes from the top to the bottom, okay?

19
00:01:24,920 --> 00:01:35,719
And the last one, longitude is distance from the equator, latitude is distance from the Greenwich Meridian, and this is false, too, okay?

20
00:01:36,099 --> 00:01:42,739
Longitude is the distance from the Greenwich Meridian, and latitude is the distance from the equator, okay?

21
00:01:43,280 --> 00:01:51,439
So, longitude, it is east or west, and latitude, it is north or south, okay?

22
00:01:51,439 --> 00:02:04,760
Okay, so you copy this, if you need to stop the video, you stop the video, okay, to correct yourself, because I'm going to correct the exercise three, so if you need to stop the video, stop it now, okay?

23
00:02:04,760 --> 00:02:06,739
Okay, right.

24
00:02:07,019 --> 00:02:15,060
So exercise three, here you have to say if it's northern hemisphere or southern hemisphere.

25
00:02:15,599 --> 00:02:17,159
Okay, so this is the equator.

26
00:02:18,300 --> 00:02:24,360
So whatever you have at the top of this, okay, above this, it is north,

27
00:02:24,639 --> 00:02:29,360
and everything that you have here at the bottom, it is south, okay?

28
00:02:29,360 --> 00:02:49,060
So, the coordinates A, B, and C will be above the equator, so E3 should be northern hemisphere, and F and C are, you know, here under the equator line, so they are southern hemisphere.

29
00:02:49,060 --> 00:03:11,840
So we will check it out. B, northern. Yes, that's okay. C, southern. Yes, that's true. And D, northern. Very good. Okay? So check your answers, and if you need to stop the video, stop it now, okay? Because I'm going to exercise number four.

30
00:03:11,840 --> 00:03:20,000
here in exercise number four you have to write the uh the coordinate the geographic coordinate

31
00:03:20,000 --> 00:03:27,979
and you have to write first of all if it's north and south and then then if it's east or west so

32
00:03:27,979 --> 00:03:38,199
you have to write b c d and e you don't have to write a so b we check out we have here this line

33
00:03:38,199 --> 00:03:41,379
that is the zero, and this one that is the 40, okay?

34
00:03:41,780 --> 00:03:50,400
So 40 above the equator line, so 40 north and zero here in the Greenwich, okay?

35
00:03:50,919 --> 00:03:54,020
40 north and zero.

36
00:03:54,639 --> 00:03:57,039
Okay, when it's zero, you don't have to say it's a rest.

37
00:03:57,159 --> 00:03:59,139
It only says zero, okay?

38
00:04:00,280 --> 00:04:00,580
Great.

39
00:04:00,919 --> 00:04:05,159
Next one, we have C, C, C, C, C, C, C, C here.

40
00:04:05,800 --> 00:04:13,800
So if we look, we have that this is the line 20 degrees, 20 degrees from the south

41
00:04:13,800 --> 00:04:17,620
because it is under the equator line, okay?

42
00:04:18,720 --> 00:04:27,800
And if we check out here, we have the 135, and this is west, and this is east, okay?

43
00:04:27,879 --> 00:04:29,199
So 135 east.

44
00:04:29,279 --> 00:04:30,160
We are going to check.

45
00:04:31,199 --> 00:04:32,579
Yay, we have it right, okay?

46
00:04:32,579 --> 00:04:37,639
20 south and 135 east, okay?

47
00:04:38,220 --> 00:04:41,779
Next one, we have the D, that is this one.

48
00:04:42,740 --> 00:04:57,699
D is in the 60 above the equator line, okay, so north, and this line, it is 105 east, okay,

49
00:04:57,759 --> 00:04:59,579
because this is west and this is east.

50
00:04:59,579 --> 00:05:04,279
We are going to check 60 north, 105 east.

51
00:05:04,459 --> 00:05:04,660
Yay!

52
00:05:05,420 --> 00:05:07,920
And the last one we have D.

53
00:05:09,319 --> 00:05:10,160
No, sorry, E.

54
00:05:10,519 --> 00:05:12,220
It is in the middle.

55
00:05:12,399 --> 00:05:14,040
It is in the equator, okay?

56
00:05:14,680 --> 00:05:20,680
And in the 15, 15 east, too, because this is west, okay?

57
00:05:21,079 --> 00:05:24,420
We'll check 0, 15 east.

58
00:05:24,720 --> 00:05:25,319
Okay, great.

59
00:05:25,819 --> 00:05:27,639
So you check your answers.

60
00:05:27,639 --> 00:05:32,300
If you need to stop the video, stop it right now, because we are going to page 11.

61
00:05:33,459 --> 00:05:33,779
Okay.

62
00:05:34,300 --> 00:05:40,079
So, page 11, you have to complete the sentences here.

63
00:05:42,000 --> 00:05:46,839
And that says, they said, the earth spins on its own.

64
00:05:47,879 --> 00:05:56,439
We call this movement, okay, la tierra se mueve por su propio axis, okay, and we call

65
00:05:56,439 --> 00:06:03,240
this movie movement rotation okay because the movement that the earth does around the sun that

66
00:06:03,240 --> 00:06:10,759
is revolution okay that's latio in espanol but here if it's uh if the earth spins on its own axis

67
00:06:10,759 --> 00:06:18,199
there is rotation rotation in spanish then the next one b is the movement that causes the seasons

68
00:06:18,199 --> 00:06:21,560
El movimiento que causa the seasons, las estaciones, okay?

69
00:06:21,939 --> 00:06:26,399
That is the movement that the earth does around the sun, okay?

70
00:06:26,500 --> 00:06:33,420
And that movement in Spanish, it is called traslación, and in English, it is revolution, okay?

71
00:06:34,040 --> 00:06:34,740
Next one.

72
00:06:34,879 --> 00:06:43,720
When it's summer in the southern hemisphere, it's in the northern hemisphere, so it is the opposite.

73
00:06:43,720 --> 00:06:47,540
So the opposite of summer, it is winter.

74
00:06:48,199 --> 00:06:52,660
Okay, next one, blah, blah, blah, is the movement that causes day and night.

75
00:06:52,800 --> 00:06:55,379
So this is the opposite to the season, okay?

76
00:06:55,459 --> 00:06:58,420
If it's not the seasons, it is day and night, okay?

77
00:06:58,819 --> 00:07:04,939
And day and night, it is only the movement that the Earth does on its own axis, okay?

78
00:07:04,939 --> 00:07:10,399
So it is the rotation movement that causes the day and night, okay, rotation.

79
00:07:11,100 --> 00:07:18,160
Then we have E, when a point on the Earth is facing away from the sun, away, okay?

80
00:07:18,199 --> 00:07:21,199
It is not looking to the sun, okay?

81
00:07:21,500 --> 00:07:22,540
It is away.

82
00:07:23,279 --> 00:07:25,459
It's night, okay?

83
00:07:25,620 --> 00:07:29,319
When it's looking, when it's facing away, it is night.

84
00:07:29,319 --> 00:07:35,079
If it's looking, if it's facing to the sun, that would be day, okay?

85
00:07:35,439 --> 00:07:38,160
But if it's facing away, that is night.

86
00:07:39,060 --> 00:07:47,319
And then we have the Earth's axis goes from the North Pole to the South Pole, yes, from the here, from the top.

87
00:07:47,319 --> 00:07:49,379
to the bottom, okay?

88
00:07:49,839 --> 00:07:51,300
Top, bottom, top, bottom.

89
00:07:51,740 --> 00:07:54,579
That is the North Pole to the South Pole, okay?

90
00:07:55,360 --> 00:07:56,920
So correct yourself, please.

91
00:07:57,639 --> 00:07:59,040
And that's all.

92
00:07:59,220 --> 00:08:00,660
That's everything for today, okay?

93
00:08:00,879 --> 00:08:01,519
Bye-bye.
