What is Autumn?
Autumn (also known as fall in North American
English) is one of the four temperate seasons.
Autumn marks the transition from summer into winter.
In the northern hemisphere, the start of autumn is generally
considered to be around September, and in the southern
hemisphere, its beginning is considered to be around March.
There exist, however, different definitions of autumn, some of
which are based on the months of the year while others are based
on the equinox and solstice.
During autumn, deciduous trees shed their leaves. Leaves
change to a yellowish, reddish or brownish hue before falling.
Such coloured leaves have come to be colloquially called
"fall foliage" in North America.
In temperate zones, autumn is the season during which most
crops are harvested. It is also the season during which days get
shorter and cooler and the nights get longer.
