Fill the blanks from the given options.
Answer to Problem 1QP
Option (b).
Explanation of Solution
Four principal geological processes that constantly reshape the terrestrial planets are impact, tectonism, volcanism and erosion. Impact cratering causes the most concentrated and sudden release of energy.
Impact cratering, tectonic, and volcanism affect Earth’s surfaced by creating variations in the height of the surface. Erosion is the wearing a way of planet’s surface by mechanical action. Erosion is not only by running water but also by wind and by actions of living organisms, wears down hills, mountains, and craters.
Conclusion:
Since impacts, tectonism, and volcanism build up structures on the terrestrial planets, whereas erosion tears them down, option (b) is correct.
Impacts, tectonism, and volcanism build up structures on the terrestrial planets, whereas erosion tears them down. Thus, option (a) is incorrect.
Impacts, tectonism, and volcanism build up structures on the terrestrial planets, whereas erosion tears them down. Thus, option (c) is incorrect.
Impacts, tectonism, and volcanism build up structures on the terrestrial planets, whereas erosion tears them down. Thus, option (d) is incorrect.

- Why do astronomers conclude that the crust on Mars must be thicker than Eths crust?arrow_forwardIn what ways is Earth unique among the Terrestrial planets?arrow_forwardEstimate the amount of water there could be in a global (planet-wide) region of subsurface permafrost on Mars (do the calculations for two permafrost thicknesses, 1 and 10 km, and a concentration of ice in the permafrost of 10% by volume). Compare the two results you get with the amount of water in Earth’s oceans calculated in Example 10.1.arrow_forward
- 1. Which of the following STILL significantly heats the Earth's interior? a. bombardment b. compression c. radioactivity d. differentiation 2. Both the Moon and Mercury have a. volcanic craters only b. impact craters only c. some volcanic and some impact cratersarrow_forward6 Why isn't there a planet where the asteroid belt is located? A The temperature in this portion of the solar nebula was just right to prevent rock from sticking together. B C D There was too much rocky material to form a terrestrial planet, but not enough gaseous material to form a jovian planet. There was not enough material in this part of the solar nebula to form a planet. Gravitational tugs from Jupiter prevented material from collecting together to form a planet. E A planet once formed here, but it was broken apart by a catastrophic collision.arrow_forward34.How old is this Martian Rock that is found to be containing 12.5% of a radioactive parent nucleus?

- When a projectile ( a rock from space, say) hits the surface of the Moon, which of the following do we NOT get? a. a crater b. an ejecta blanket c. secondary craters d. a rough hilly apron (or slope) of ejected material e. a gushing out lots of water that had been frozen inside the ground of the cold Moon, but it is briefly heated by the impactarrow_forwardFor 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.arrow_forwardScientists find evidence of a large meteor impact on the coast of the YucatánPeninsula in Mexico. What can the scientists most likely expect to find in the layers of rock that are about the same age as the impact?A. evidence of the mass extinction of many speciesB. evidence of a gradual change of one species over timeC. evidence of a rapid change in one speciesD. evidence of the stability of many species over timearrow_forward
