Objectives Week 4 1. Know the two broad categories of planets. 2. Know that seven large satellites are almost as big as the terrestrial planets. Why are we interested in some of the satellites of the outer planets? 3. Know how spectroscopy reveals the chemical composition of the planets. The light we receive from a planet or satellite is reflected sunlight—but with revealing differences in its spectrum. 4. The Jovian planets are made of lighter elements than the terrestrial planets Differences in distance from the Sun, and hence in surface temperature, explain many distinctions between terrestrial and Jovian planets. 5. The concepts of kinetic energy and thermal energy can be combined with the concept of escape velocity to form the basis for the theory of the retention of planetary atmospheres.

Unformatted text preview: 6. Small chunks of rock and ice also orbit the Sun. The smaller bodies of the solar system contain important clues about its origin and evolution. 7. Cratering on planets and satellites is the result of impacts from interplanetary debris. The earth also shows evidence of impact cratering. Why doesn’t earth seem to have as many craters as some other planets and moons? 8. The diversity of the solar system is a result of its origin and evolution. The similarities and differences among the planets can be logically explained by a model of the solar system’s origin and evolution. 9. Know the significance of a planetary magnetic field....
