About This Chapter
The Earth-Sun Relationship - Chapter Summary
If your middle-schooler has been studying geography in class or would like to learn more about the solar system, these short, entertaining videos are a great resource. In these lessons, students examine the theories of Earth's formation, learn about how the tilt of the Earth and its position around the sun affects the climate, and discover our place in the universe. Use the lesson quizzes to see how well your student understands the concepts and help him or her prepare for class exams.

1. Formation of the Earth: Theories
The planet Earth has over 4 billion years of existence and its existence derives from interstellar dust and gas. Explore the theories that explain how the planet Earth was formed, including how it differentiated into three layers, how it formed its atmosphere, water, and land features, and how it continues to evolve today.
2. Earth's Location in the Solar System
Our solar system, galaxy, and universe can all be mapped, despite their vast complexity. Learn about Earth's location in the solar system, and explore details of how the Milky Way, galaxies, clusters, and even the 'center of the universe' are mapped.
3. Earth's Axial Tilt & Orbit Around the Sun
The Earth's axial tilt exists as the planet's spin is not aligned with the travel of orbit. Learn how the Earth orbits the sun, and the details of orbital plane & eccentricity, and the axial tilt and precession.
4. Geography of the Four Seasons
The geography of the four seasons is affected by the earth's rotation. Learn about the differences in seasons as affected by the earth's axis and rotation, and examine the earth's solstice between hemispheres.
5. Why the Sun Changes Color
The sun changes color based on our perception and the position of the sun at a given time. Explore the changing colors of the sun, wavelengths of light, and how they determine color, prisms, and the setting sun.
6. The Sun's Path Through the Local Sky
Every day, the sun appears to travel east to west across the sky before making its descent. Explore the sun's path through the local skies of locations around latitude 40 degrees north, the North Pole, the South Pole, and the Equator.
7. Using the Sun & Stars to Determine Latitude & Longitude
Because of their consistent positions and movement across the sky, the sun and stars are useful tools for determining location. Learn how the sun and stars can be used to determine one's latitude and longitude at any time of day.
8. The Sun's Angle & Movement
Our seasons and daylight hours are influenced by the Sun's position at any given time. Discover how the Sun's angle and movement affect seasons, the length of days, and both the Southern and Northern hemispheres.
9. The Equator, the Tropics of Cancer & Capricorn: Association with Earth-Sun Geometry
As people all across the world are unique, so too are the locations of people, places, and things. Learn how longitude and latitude are used to measure distance on Earth and the location of the Equator and tropics.
