science. In the diagram, letters A, B, C, and D represent Earth’s location on the first day of the four seasons as it orbits the Sun. Aphelion [Earth’s farthest distance from the Sun] and perihelion [Earth’s closest distance to the Sun] are labeled to show the approximate positions where they occur in Earth’s orbit.
Standard 4 Key Idea 1. Performance Indicator 1.1. Explain complex phenomena, such as tides, variations in day length, solar insolation, apparent motion of the planets, and annual traverse of the constellations. Major Understanding:
Imagine a line passing through the center of Earth that goes through both the North Pole and the South Pole. This imaginary line is called an axis. Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth’s rotation.

Earth’s Motions. What evidence do we have to provide evidence of Earth’s motions and how do calculate its elliptical orbit? Rotation - the movement of an object in a circular motion around a line of axis. Period of Rotation - amount of time to make one complete rotation. Example: Earth rotates 360o in 24 hours.
