There was a boy named Billy. His birthday fell in nice and warm summers. Every year he celebrated his birthday on 22nd December. Are you surprised? I sure was..
You see the Earth is a sphere and can be divided into two hemispheres. The line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere is equator .
The Northern Hemisphere includes all of North America, the northern parts of South America, about two-thirds of Africa, all of Asia excluding (parts of Indonesia) and all of Europe.
The Southern Hemisphere includes most of South America, one-third of Africa, all of Antarctica, a small sliver of Asia (parts of Indonesia) and all of Australia/Oceania.
These Hemispheres have very interesting facts about them
- The Northern Hemisphere has almost 90% of the land and the Southern Hemisphere has 90% water. So most of the world population lives in Northern Hemisphere.
- When its is summer in the Northern Hemisphere, its winter-time in Southern Hemisphere.
- Moon seems to be upside down in the Southern Hemisphere.
- Sun rises in East and sets in West in both Hemispheres. Atleast they have something in common
Coming back to our question that how Billy celebrated his birthday on Dec 22 in summers? He lived in Australia :)
