Hello Happy friends!
Are you ready to learn?
Iâm Sarah, and Today, weâre going to learn a little more about the seasons, and to do this, weâre going to learn about the hemispheres.
-
We all know, that there are four seasons in a year, spring, summer, autumn and winter. And that each one of them has different weather conditions.
-
In winter, itâs very cold
In spring, temperatures start to rise, and of course, flowers start to blossom.
In summer, itâs usually extremely hot
And, in autumn, temperatures start to decrease, and leaves start falling from trees.
-
But⊠Did you know that the seasons donât happen at the same time all over the world?
Nope! they donât, so letâs find out why!
-
Planet Earth, has an axis, an imaginary line, where the earth spins around itself, in a rotational movement.
-
This axis is not up straight, itâs actually leaning, and depending on the month of the year, there are areas that receive more heat than others.
-
Our planet is also divided into two parts, separated by an imaginary line called equator.
This line, divides the earth into two hemispheres: the Northern Hemisphere, and the Southern Hemisphere.
-
Now, letâs see how our planet moves around the sun.
Itâs what we call a translation movement.
-
As you can see, the sun heats the Earth, but not equally around the whole world.
Letâs stop the planet. Stop!
In this position, the northern hemisphere has more sun rays, because of the axis inclination.
And that means⊠Weâre in summer! And meanwhile, in the southern hemisphere itâs winter.
buff I prefer summer!
-
But, what happens if the Earth rotates on the other side of the sun?
Well, there would be more rays in the southern hemisphere, meaning that in the northern hemisphere, itâs winter, and in the southern hemisphere, itâs summer.
Easy peasy huh?
Goodbye happy friends! See you next time!
I hope youâre always ready to learn!
Goodbye!
