Textbook Question

Chapter 9, Problem 28EAP

Surprising Discoveries?

Suppose we were to make the following discoveries. (These are not real discoveries.) In ligh of your understanding of planetary geology, decide whether the discovery should be considered reasonable or surprising. (In some cases, both view can be defended.) Explain your answer, if possible tracing your logic back to the terrestrial worlds' fundamental properties of size, distance from the Sun, and rotation rate.

28. We find a planet in another solar system that has Earth-like seafloor crust and continental crust but apparently lacks plate tectonics or any other kind of crustal motio.

How many impacts would you expect to strike a 100m2 region in one hour during Earth’s formation, assuming that Earth grew to its present size in 10 million years from particles averaging 100 grams each? (Hint: Assume that Earth had its current radius of 6378km.) (Notes: The surface area of a sphere is 4pir2 ; 1yr=3.2x107 .) a. About 1300. b. About 13 . c. About 13,000. d. About 130

For which of the following reasons (select all that apply), is it useful/important to send rovers to other planetary bodies in our solar system? a. More direct probes of the planetary surface are possible to detect signs of the building blocks of life. b. Rovers/landers can be outfitted with various tools and equipment that can be used to inform of us of the geological histories of each of the planets they visit. c. Rock samples can be used to calibrate our estimations of the age of the solar system. d. The data collected can help improve our understanding of the evolution/development of our solar system. e. The engineering innovations developed to produce successful/viable rovers and landers on other planets can help lead to developments in the technology used here on Earth that may have taken far more time to develop without the limitations provided by space travel to foreign worlds.

Planetary scientists are hoping that the samples collected by the Perseverance Mars rover will eventually be collected by other robotic spacecraft and returned to Earth. Even if Perseverance could collect samples from all over Mars's surface, why wouldn't this tell us what the entire planet is made of? Group of answer choices The deep interior of Mars has had its composition altered (compared to the surface) by the impacts of asteroids that plunged almost all the way down to Mars's center. Since Mars has a powerful magnetic field, it must have a liquid-iron portion of its core, and this material can't be collected by a rover on the surface. Early in its history, Mars differentiated into layers of materials that had different densities, much like the Earth did. Mars has such a low density that most of its interior must be made of liquid water and ice, so rocks from the surface simply won't be representative of the deep interior.
