Autumn is also a time for harvest. Farmers harvest their crops, such as corn, soybeans, and wheat.

Autumn is a time for many festivals and celebrations. In the United States, there is Thanksgiving Day, which is a holiday to celebrate the harvest. In the United Kingdom, there is Halloween, which is a holiday to celebrate the dead.

Autumn is a special season. It is a time of change, beauty, and harvest.

Here are some fun facts about autumn:

• The word "autumn" comes from the Latin word "autumnus," which means "autumn."
• The leaves on the trees change colour because of the amount of sunlight they receive. When the days get shorter, the leaves start to produce less chlorophyll, which is the green pigment that gives leaves their colour.
• The first day of autumn is called autumnal equinox. On this day, the day and night are equal in length.
• Autumn is a popular time for hiking, biking, and other outdoor activities.
