Hemispheres

Hello friends, welcome to a new Happy Learning video. Do Well, let's find out some more because today we're going to learn about the equator and the hemispheres. The equator is an imaginary line that divides the Earth horizontally, right down the middle, as if were splitting it in two. Everyt The northern hemisphere and the southern hemisphere are exactly the same size but they have many differences. Above all, the most eye-catching thing is that when it's Do It's very easy. Check t If we observe the Earth, we realize that its axis, the imaginary vertical line that crosses from pole to pole, is not straight, it's tilted. That means that when the Earth revolves around the Sun, there is a part that is closer to it and warmer and that's why it's Meanw That explains that w Another important difference we can observe is that most of the continents are in the northern hemisphere. Do you see Europe, North America, almost all of Asia, a good part of Africa and a little bit of South America are in the northern hemisphere and therefore we can say that many more people live in the northern hemisphere. The southern hemisphere is emptier, it contains Antarctica, southern Asia, a bit of Africa, Oceana, most of South America and lots of water. But there are more surprising, super fun t For example, the moon. When the moon is in its crescent phase in the northern hemisphere, it can be seen shaped While in the southern hemisphere, it'shaped It's more or less in reverse. If we the Coriolis force is another extremely curious phenomenon. Isn't it such a strange word? The Coriolis force is a physical phenomenon that due to the Earth's rotational movement makes w Those that are produced in rivers rotate in reverse in the different hemispheres. In the northern hemisphere, they always turn to the right and in the southern hemisphere, they always turn to the left. Curious, isn't it? You can check t If you fill a sink with water and remove the plug, observe w That way, you will be able to tell w It's always good to check that everyt Get ready, because today we're going to play a game. That's right, we're going to play all over the planet and for that, we're going to use somet Imagination! Today, we're going to learn about imaginary lines called parallels and meridians. Many, many years ago, the earth scientists decided that in order to understand the earth better, it was a very good idea to create imaginary lines. These imaginary lines have a name. They are called parallels and meridians. Parallels are circular lines that encircle the planet from east to west. They're just imaginary, but we're going to draw them The longest horizontal imaginary line is the equator, w Of course you do! Well, remember its name, because it's very important for our game today. The equator is the parallel that divides the earth into two halves, the northern hemisphere and the southern hemisphere. Other important parallels are the tropic of cancer and the Arctic Circle, w But as you can see, there are many more lines. The distance from any point on the planet to the parallel of the equator is called latitude and it's measured in degrees, but not in degrees relating to hot or cold, but in degrees of distance, w Intense! It works Upwards is northern latitude or positive latitude and downwards is southern latitude or negative latitude. For example, if we are here at that's it! We're at a latitude of 30 degrees south. Well, we already know the parallels. Now it's time for the meridians. The meridians are semi-circular imaginary lines that go from the north pole to the south pole, just The most important meridian is one that passes through a place in England called Greenwich. And do Well, it's very easy. It's called the Greenwich Meridian. You have to admit, the scientists didn't use much imagination there, did they? The Greenwich Meridian divides the earth into the eastern hemisphere, w And the western hemisphere the distance from any point on earth to the Greenwich Meridian, w It ranges from zero to 180 degrees west, also known as negative degrees, in the western hemisphere. In the eastern hemisphere, it also ranges from zero to 180 degrees east. For example, if we are here, we are at the distance 10, 20, 30, 40 degrees west longitude, w If we draw all the meridians and all the parallels of the earth, we have a grid. The geograp Let's try it. T So t Now, let'say we're at 20 degrees south latitude, and 20 degrees east longitude. Where are we? Let'see, 10, 20 south latitude, here, 10, 20 degrees longitude, here. We're in Africa. Maybe we'll see some lions. How exciting. Now you have to find out what coordinates your country is at. Of course, there is nothing better than using your imagination to create fantastic things Goodbye friends,
