Earth in the Solar System (Earth Science)
PS.4. The structure and composition of the universe can be learned from studying stars and galaxies and their evolution. As a basis for understanding this concept:
PS.4.b. Students know that the Sun is one of many stars in the Milky Way galaxy and that stars may differ in size, temperature, and color.
PS.4.e. Students know the appearance, general composition, relative position and size, and motion of objects in the solar system, including planets, planetary satellites, comets, and asteroids.
PS.2. Unbalanced forces cause changes in velocity. As a basis for understanding this concept:
PS.2.g. Students know the role of gravity in forming and maintaining the shapes of planets, stars, and the solar system.
