Key Idea 1: The Earth and celestial phenomena can be described by principles of relative motion and perspective.
- 1.1h The apparent motions of the Sun, Moon, planets, and stars across the sky can be explained by Earth’s rotation and revolution. Earth’s rotation causes the length of one day to be approximately 24 hours. This rotation also causes the Sun and Moon to appear to rise along the eastern horizon and to set along the western horizon. Earth’s revolution around the Sun defines the length of the year as 365 1/4 days.
- 1.1i The tilt of Earth’s axis of rotation and the revolution of Earth around the Sun cause seasons on Earth. The length of daylight varies depending on latitude and season.
- 1.1j The shape of Earth, the other planets, and stars is nearly spherical.
Key Idea 2: Explain how the atmosphere (air), hydrosphere (water), and lithosphere (land) interact, evolve, and change.
- 2.2j Climate is the characteristic weather that prevails from season to season and year to year.
