Hello friends, today we'll learn about the latitudes and longitudes of the Earth.
00:00:00
Have you ever wondered how the location or position of any place is determined?
00:00:06
Let me explain this. Whoa, it looks so yum! Our Earth looks like an orange. It is spherical from
00:00:12
the sides and flat at the top and bottom. The latitudes and longitudes are invisible lines
00:00:24
that help us identify a place using geometrical coordinates.
00:00:32
An easy way to remember the orientation is that latitudes are lateral
00:00:37
and longitudes are long. Let's learn about them one by one.
00:00:44
At first, latitudes.
00:00:51
Latitude lines circle the globe in east-west direction.
00:00:54
It measures how far north or south a specific point lies from the equator.
00:00:58
They're also known as parallels.
00:01:04
The equator at zero degrees separates the Earth into northern and southern hemisphere.
00:01:07
Locations to its north lies in between zero degrees north to 90 degrees north,
00:01:14
while to its south the positions are between zero degrees south and 90 degrees south.
00:01:20
The distance between each degree of latitude is approximately 69 miles.
00:01:26
And now, the longitudes.
00:01:32
Longitudinal lines run from the North Pole to the South Pole.
00:01:35
It measures how far east or west a point lies from the prime meridian.
00:01:40
These are also known as prime meridians.
00:01:45
Longitudes can value from 0 degrees to 180 degrees east.
00:01:49
The distance between longitudes at the equator is the same as latitude, roughly 69 miles.
00:01:54
At 45 degrees south or north, the distance between is about 49 miles.
00:02:02
The distance between longitudes reaches to zero at the poles
00:02:09
as the lines of meridian converge at that point.
00:02:13
Now we'll see some of the notable latitudes and longitudes.
00:02:18
The most important of these are the equator and the prime meridian.
00:02:22
The equator is a line passing through the center of the Earth
00:02:27
and is considered as the reference point for latitudes,
00:02:31
whereas the prime meridian is a line passing through Greenwich, England
00:02:34
and is considered as the reference point for longitudes.
00:02:39
Hmm, it is also the source to calculate time and international dateline.
00:02:43
Each degree refers to four minutes.
00:02:49
There are 24 time zones in the world. If an event happens at 11 a.m. in Greenwich,
00:02:52
England, it would be reported at 4.30 p.m. in Kolkata, India. The other important latitude
00:02:58
is the Tropic of Cancer in the north and the Tropic of Capricorn in the south.
00:03:06
Apart from these, the Arctic and Antarctic circle at 66.5 degrees north and south respectively
00:03:12
are equally necessary.
00:03:19
These latitudes divide the Earth into the tropic zone.
00:03:22
It's the hottest zone with countries like Colombia, Brazil, Kenya.
00:03:26
Temperate zone, the moderate zone,
00:03:31
with countries like India, Japan, United States of America.
00:03:34
And the polar zone, the coldest zone,
00:03:39
with countries like Norway, Iceland, and Finland.
00:03:42
Penguins live in the polar zone's southern hemisphere.
00:03:46
That's it for today, kids. Stay tuned for next video. Bye-bye!
