After the link to TED was posted a few threads below, I began to browse through the videos and I found this one which I liked a lot.
I got questions 1 and 2 right. But the 3rd and 4th questions wrong and along the lines of the misconceptions he was referring to. I understood 4 myself but his explanation for 3 was a bit brief and I'm not sure I got it. Could someone explain the answer to Q3?
Therefore, we do not know what you are talking about.youtube said:The URL contained a malformed video ID.
That's better. Question 3 was: Why is it hotter in the summer than the winter?
I would assume it's because the quality of the sunlight is not the same. The sunlight hitting the equator is straight on, whereas more light is reflected back into space near the poles.That's better. Question 3 was: Why is it hotter in the summer than the winter?
I would say the answer gets easier the further from the equator you grew up. Imagine living on the north pole. 24 hours of sun in the summer and zero hours of sun in the winter.
Hmmm.... So why doesn't the north pole melt in the summer if it's sunny 24 hours a day?
