Solar System Trends. Study the planetary data in Table 7.1 to do each of the following.
a. Notice the relationship between distance from the Sun and surface temperature. Describe the trend, explain why it exists, and explain any notable exceptions to the trend.
b. The text says that planets can be classified as either terrestrial or jovian, with Pluto fitting neither category. Describe in general how the columns for density, composition, and distance from the Sun support this classification.
c. Describe the trend you see in orbital periods, and explain it in terms of Kepler’s third law.

- We believe that all of the terrestrial planets had similar histories when it comes to impacts from space. Explain how this idea can be used to date the formation of the martian highlands, the martian basins, and the Tharsis volcanoes. How certain are the ages derived for these features (in other words, how do we check the ages we derive from this method)?arrow_forwardSuppose that Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On the average, how many particles did Earth capture per second? (Note: Earth’s mass is 6.01027 grams.)arrow_forwardHow does the solar nebula theory explain the orbits of the major planets? Dwarf planets? Does it explain the rotations of the planets? Why or why not?arrow_forward
- How do terrestrial and giant planets differ? List as many ways as you can think of.arrow_forwardDescribe the current atmosphere on Mars. What evidence suggests that it must have been different in the past?arrow_forwardDescribe the solar nebula, and outline the sequence of events within the nebula that gave rise to the planetesimals.arrow_forward
- What does the term differentiated mean when applied to a planet? Would you expect to find that planets are usually differentiated? Why?arrow_forwardIf, in the remote future, we establish a base on Mercury, keeping track of time will be a challenge. Discuss how to define a year on Mercury, and the two ways to define a day. Can you come up with ways that humans raised on Earth might deal with time cycles on Mercury?arrow_forwardWhich step(s) listed in the previous question can be eliminated in models that form Jovian planets in thousands of years, a time frame that solves the Jovian problem? Order the following steps in the formation of a Terrestrial planet chronologically: gravitational collapse, accretion, outgassing, condensation, and differentiation.arrow_forward
- If you stood on Earth during its formation, during which it captured about 1.4 ✕ 1011 particles per second, and watched a region covering 310 m2, how many impacts would you expect to see in an hour? (Notes: The surface area of a sphere is 4πr2. Hint: Assume that Earth had its current radius of 6,378 km.) [......] impactsarrow_forwardWhy Wait? To explore a planet, we often send first a flyby, then an orbiter, then a probe or a lander. There’s no doubt that probes and landers give the most close-up detail, so why don’t we send this type of mission first? For the planet of your choice, based just on the information in this chap- ter, give an example of why such a strategy might cause a mission to provide incomplete information about the planet or to fail outright.arrow_forwardActivity #1. Compare and Contrast. Similarities and differences of Venus, Earth and Mars. Do this on a separate sheet of paper. 1. Compare and contrast the three (3) terrestrial planets using table 1. 2. Provide explanations for your observations using table 2. 3. Answer the following guide questions. Guide questions: 1. Does planet size affect gravity? 2. Why do you think Venus has the highest mean temperature among the three planets? 3. Is presence of water a primary factor for a planet to sustain life? Why or why not? 4. Based on your observations using table 2, what are the notable features that makes the earth the only habitable planet among the three terrestrial planets? 5. What conclusions can you make?arrow_forward
