The differences between spring and autumn include temperature, time of year and length of day. Spring is the season that happens after winter, while autumn is the season that happens after summer. The physical appearance of spring and autumn are different as well, as trees bloom in spring and turn in autumn.
Spring happens between the seasons of winter and summer. The first day of spring is always marked on the calendar as March 20th in the Northern Hemisphere and September 22 in the Southern Hemisphere. The temperature lies in between the winter cold and gradually heats up towards the beginning of summer. In the spring trees, flowers and plants can be seen in full bloom. This is also the time of year that many baby animals appear, and spring is known as the season of new beginnings.
Autumn happens between the seasons of summer and winter. The first day of autumn is September 22 in the Northern Hemisphere and March 20 in the Southern Hemisphere. The temperature in the beginning starts out rather warm and gradually cools off to get ready for winter. In the autumn, plants begin to die, leaves change colors and fall off of trees, plants begin to wilt and many animals prepare for winter hibernation. Autumn is known as the cooling-off season.
