Ten facts about me
People born in Autumn live longerĪ study in the Journal of Aging Research found that babies born during the autumn months are more likely to live to 100 than those born during the rest of the year. The chemicals responsible are types of flavonoids, carotenoids and anthocyanins.ĭid you know some of these chemicals are the same ones that give carrots (beta-carotenes) and egg yolks (luteins) their colours? 4. These are responsible for the vibrant ambers, reds and yellows of autumn. The chemistry of colourĬhlorophyll is the chemical which makes tree leaves green and as it declines other chemicals become more prominent in the leaves. The shorter days are a sign to trees to begin to prepare for winter.ĭuring winter there is not enough light for photosynthesis to occur, so as the days shorten throughout autumn, the trees begin to close down their food production systems and reduce the amount of chlorophyll in their leaves. One of the most stunning signs of autumn is the turning of the leaves. However, to record climate data, it is important to have set dates that can be compared, so meteorological autumn always begins on 1 September. Autumn, as defined by the Earth's orbit around the Sun, begins on the equinox which falls on 22 or 23 September. There are two different dates when autumn could be said to begin.
