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!

THE EARTH ROTATES!

HI EVERYONE! THIS IS MY POST!
I'm actually not really sure what to write about. Its supposed to be on the lesson that we learnt the about how the earth rotates around the sun. I really dont know what to write about. So i shall just write the main part of the lesson which is the earth going around the sun!

haha! i drew what i drew on my notes. please tell me if its wrong:/

The sun stays put and the earth rotates around the sun so it different parts of the world will experience summer and winter because of the angle which is tilted. Like in the summer solstice the northern hemisphere is tilted towards the sun so it experiences summer. i think. But the north pole is still cold because of the beam spreading.

oh! Those who cant really visualize it go and find videos, like the one shown in class!

byee! i dont know why i;m posting this when its exams:) but bye!

RIKAKWAH!
