the temperature and in the spring leaves are green and in the fall leaves turn brown and fall off of the trees.
Basically, autumn is the beginning of this season. It is the weeks during which the change happens after summer, when you can feel that crispness creep into the air and you know that the summer is over. It is the time of year where, in many places, the colors of the leaves are bright and eye-catching. And autumn is associated with excitement about this change. In contrast, fall is when the leaves have actually fallen off of the trees and are down on the ground. The air is cold all of the time so that the crispness isn't so much refreshing as just standard. And instead of excitement about the season, most people are anticipating the winter holidays.
Both, really.
Autumn has been used since the 14th Century, Fall is much later, during the 17th Century. Usage of Fall has declined, and really now is only used in the US, but that doesn't mean it's less valid.
ANSWER
The answer goes back to the seventeenth century, when the first great wave of emigrants crossed the Atlantic. At that time, both autumn and fall (often as part of the phrase fall of the leaf) were common in England. After the Revolution, British usage began shifting to the more Latinate term, influenced perhaps by Continental usage (French automne, Spanish otono, Italian autunno) or upper-class striving for refinement. Americans, much less affected by such influences, stuck with their Yankee ancestors' simple and direct term. John Keats, an Englishman, began his "To Autumn" with the lines, "Season of mists and mellow fruitfulness / Close bosom-friend of the maturing sun." By contrast, James Whitcomb Riley's peerless American poem about the season climaxes with "Oh, it sets my heart a-clickin' like the tickin' of a clock / When the frost is on the punkin and the fodder's in the shock." A nation that could produce those lines was bound to opt for the short and bluntly descriptive term over the more cultivated Old World variant.

Taking the vocabulary of Old English as a starting point, both Fall and Autumn as names for the season between summer and winter are late-comers.
Fall derives from an Old English verb, but it wasn't used as a noun to designate the season until the 16th century. This use most likely developed from the Middle English expression "fall of the leaf."
So what did Old English speakers call the season?
Harvest.
The need for a new word arose from a population shift that made cities more important than farmland. From being a word for the season, harvest came to refer only to the agricultural event that occurs in that season.
Autumn as a word for the season came into common usage about the same time as Fall did. The English who settled the eastern American seaboard brought the word Fall with them from the homeland. The English who stayed home eventually adopted the word Autumn.
Nowadays in England "Fall" sounds archaic and poetic, but in U.S. English "Autumn" has those connotations.

The popular definition of Autumn differs from Fall. Autumn is when the foliage changes color as an indication of the end of summer. Fall is when the leaves fall.
The words "fall" and "autumn" are synonymous. The term "fall" was widely used in England and the American colonies in the 17th and 18th centuries. In Britain, it became obsolete and was gradually replaced with "autumn" in the 19th century, while Americans continued to use the word "fall".
This may be another case of the duality of Middle English after the Norman Conquest. The word "fall" can be traced to Old English (Anglo-Saxon) vocabulary, while "autumn" comes from French.
