Weather

Hello! Now almost students are in examination period. How about your examination?

I think the "weather" influence on your motivation for examination- if it is rain in examination day, you are depressed, but if it is sunny, you are positive to take examination.

However, it is really strange weather in England nowadays- BBC caster said "It is MAY not be MAY"- yes, I think it is May not be May in England.

Anyway, today's topic is weather- I will talk about "weather trivia" (Tribia means unimportant or obscure information)

1: Why is the sky blue?

- This is because of the function of PRISM: A prism splits visible light into the colors of the spectrum. This pectrum influence on our vision, and the color is looked "ike" blue- so, if the spectuum is not blue but red, the sky would have Red Sky-. anyway, it is difficult to explain the function of prism, but please notice, the color of sky is not reflected to the color of Sea!!

2: Can ants forecast weather?

- This is true. Ants can forecast weather. As you know, ants can not suvive in the water, thus if it rain, ants may be dead. So, ants can notice the change in atomsperic pressure, and then they will fill in thier hole to prevent from water. If you see ants hole, and ants are filling it in, it means that it will rain soon.

3: If Swallow fly low, it means it will be rain

- This is also true, because there are a lot of humidity before raining. Some insects can not fly high because oh the moisture- they feel heavy. And some birds fly low to eat these insects which can not fly high- so some birds need to fly low. If you find some birds can not fly high, it may mean that it will rain soon.

These tribia may not apper in your examination, but sometimes tribia is nice to refresh your mind!
