Autumn at USD Mrican Campus?

Sun, 21 Oct 2012

What season now in Yogyakarta or in Indonesia as a whole? Rainy one? Nearly, perhaps. Many countries throughout the world have different seasons at a different time. Right now -- October, for example, it is the spring in Southern Hemisphere, for instance, in New Zealand but the autumn in Northern Hemisphere, like in England and in the east coast of the United States, such as in Boston and New York. 

Well, in Mrican, Yogyakarta, especially at USD Mrican Campus Two, some trees beside the football field have also been changing colours from green to orange and yellow; we were as if welcoming the autumn or fall (musim gugur). In the autumn, it is common, natural for tree leaves to change their colours. Below are pictures of orange-yellow leaves  taken at USD Mrican Campus Two, beside the football field, on Saturday 20 October 2012 around 7.30 in the morning.  

 

Question: Why do tree leaves change colour in the autumn or fall? 

Answer: "The simple answer is that, during summer, chlorophyll in the leaves is so densely green that it hides the yellow and orange colors of other chemical compounds that are also there. But when chlorophyll begins to disappear with the oncoming cold season, the oranges and yellows are exposed. At the same time, in autumn, red chemical compounds are produced in large quantity by some trees, and these are added to the orange and yellow" (source: www.sciencebuff.org/collections/research-collections/botany/bright-fall-colors/ accessed on Sunday 21 Oct 2012)

We order or sequence the four seasons as follows: 1. spring, 2. summer, 3. autumn (British English) or fall (American English) and 4. winter.
