The document discusses the causes of seasons on Earth. The two main causes are the Earth's orbit around the sun and the 23.5 degree tilt of its axis. Because the axis is tilted and not vertical, as the Earth revolves it causes different parts of the planet to receive more or less direct sunlight over the course of a year, resulting in the seasons we experience. If the axis was not tilted, there would be no seasons, and a straight vertical axis would result in consistent weather worldwide.

1. The Truth about Seasons By: Marie and Casey

2. Changing Seasons There are two things that cause the change in seasons. 1. The earth’s orbit. 2. The tilt of the earth’s axis.

3. The Earth’s axis is the cause of our seasons. It is not vertical, but slanted at a 23.5 degree angle. If it were not slanted, we would not have seasons. Axis's Shape

4. If the axis was at 90 degrees the northern hemisphere would have some very cold weather for a 6 month long winter. The southern hemisphere would have a very hot 6 month long summer. A Different Axis

5. A Straight Axis If the axis was straight, we would always have forever sun with no change in seasons or temperature!

6. The Axis is the Cause of our Seasons Our Axis's angle degree is 23.5 It takes the Earth 1 year to orbit. In summer, the earth is tipped to the sun. In the winter, the earth is tipped away from the sun. Random Facts!!!!!

7. Bye!!! Thanks for listening!!! Hope you learned a lot!
