We think the terrestrial planets formed around solid “seeds” that later grew over time through the accretion of rocks and metals. a) Suppose the Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On average, how many particles did the Earth capture per second, given that the mass of the Earth is = 5.972 × 10 ^24 kg ? b) If you stood on Earth during its formation and watched a region covering 100 m^2, how many impacts would you expect to see in one hour. Use the impact rate you calculated in part a. You’ll need the following as well: the radius of the Earth is = 6.371 × 10 ^6 m and the surface area of the Earth is 4??^2Earth
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.) [......] impacts
Which 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.
If, 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?
How 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?
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)?
Order the following steps in the formation of a Terrestrial planet chronologically: gravitational collapse, accretion, out-gassing, condensation, and differentiation.
Describe the current atmosphere on Mars. What evidence suggests that it must have been different in the past?
Suppose 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.)
How long would radio signals take to travel from Earth to Venus and back if Venus were at its nearest point to Earth? At its farthest point from Earth? (Notes: The speed of light is 3.00 108 m/s. Necessary data to derive the distances between the objects in those two situations are given in the Celestial Profiles for Earth in Chapter 19 and Venus in this chapter.)
How does the solar nebula theory explain the dramatic density difference between the Terrestrial and Jovian planets?
What does the term differentiated mean when applied to a planet? Would you expect to find that planets are usually differentiated? Why?
