THE TASK 
Use the information in the following website to conduct research to answer the question "What causes seasons?".
Use the information collected to create a poster explaining how the Earth's tilt and yearly orbit around the sun affect seasonal changes.


Earth’s Tilt

Earth’s Location and Seasons

As the Earth revolves around the Sun, the tilt of the Earth affects the seasons. The direction of the tilt never changes. It is always pointing towards the North Star (Polaris)
