Earth's Tilt and Sun Path Concepts

The video tutorial covers the concept of sun paths, explaining how the sun's position changes throughout the year due to the Earth's tilt. It discusses the patterns of sunrise and sunset, the significance of equinoxes and solstices, and how shadows vary with the sun's movement. The tutorial includes practical exercises and a Q&A session to reinforce understanding of these concepts.

What are the four main compass directions that are always included in a sun path diagram?

• South, West, Left, Right

How does the Earth's tilt affect the sun's path throughout the year?
