HELLO! :D
okay so i'd be doing on CLIMATE (:
firstly, weather and climate are different!
weather= atmosphere at local level for a short period of time. e.g. sunshine, cloud, wind, rainfall, temperature.
climate= long term behaviour of atmosphere in specific area. Data on temperature, wind, precipitation, humidity etc are used to build up global patterns.
Regarding shape of the earth, there are two things to note:
1. beam spreading (biggger/smaller surface area of beam spread)
2. beam depletion ( amount of beam depleted as it goes through more/less atmosphere, thus less/more intense beam)
Since poles always have bigger beam spreading and more beam depletion, its forever more cold! (:
recap that earth rotates ANTI-CLOCKWISE direction on its axis when we look down on north pole. Axis 23.5 degrees away from right angle. *Relate to different length of exposure to sun and beam spread and depletion*
earth revolves around sun in COUNTER-CLOCKWISE direction when we look from the top too.
i find this video quite helpful in explaining how seasons occur.

kay thats all
BUHBYE!

helloo :D your post helped me understand more on how the shape of the earth and its rotation is linked with climate! so i guess climate more or less leads to the seasons? but i was just wondering, are the poles forever having winter as their season then? :O

ReplyDeletehello jiaying. Information given was very detailed, i understood alot! maybe you could also explain what happens in the video? :D
