Earth is divided into two parts by an imaginary line called equator. The two parts are named as northern hemisphere & southern hemisphere.
These hemispheres have many strange facts related to them:
- - Northern hemisphere contains most of the earth’s land area and most of the human population (about 90%).
- - Southern hemisphere is about 90% sea.
- - Weather patterns are opposite to each other, for example when north has winter weather, south enjoys summer.
- - Sun rises from east & sets in west in both parts but shadows move clockwise in north and anti-clockwise in south.
- - High winds, water currants in sea & airplanes tend to bend or curve clockwise in north and counterclockwise in south.
- - Moon appears upside down in south compared to north. The northern hemisphere is more suitable for deep-space observations because the stars are far more visible & are much brighter.
- - The earth rotates at about 1000 KM / hour at the equator but is nearly static at poles.
- - The days & nights are of same length all year around on equator. But days get shorter on poles during winter and longer during summer.
- - Near the poles there is every year a summer period in which it is day only, a winter period in which it is night only, and the rest of the year one day and night every 24 hours.
- And last but not the least: If you have a bucket full of water with a hole in the middle, the water draining through the hole will start cirlcing clockwise in Northen and anti-clockwise in Southern hemisphere. And there will be no circular motion at all at the equater. Don’t believe me? See for yourself here.
Strange isn’t it!
