Which of the following is least reasonable regarding impact craters?
Group of answer choices
The size and shape of the crater and the amount of material excavated depends on factors such as the velocity and mass of the impacting body and the geology of the surface.
Craters are most often are circular but more elongate craters can be produced with impactors striking the surface at very low angles.
The Moon has more craters than the Earth because of its strong tidal force on the impactors.
Objects from space typically hit Earth at about 20 km/s ande produce craters that can be approximately 20 times larger in diameter than the impacting objects.
The faster the incoming impactor, the larger the crater.
Scientists 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 time

- 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 130arrow_forwardHellas Planitia includes the word "planitia" which is the latin word for "plain" in its name. The name would seem to indicate thats Hellas Planitia is a low lying plain, yet it is clearly a crater, and a very large one at that. The most probable reason for this discrepancy in its name is because: a. It is a simple naming error that for some reason has so far escaped correction. b. There is a disagreement among astronomers about the true nature of Hellas Planitia. c. Its true nature was not apparent over 100 years ago when it was observed using ground based telescopes. d. Astronomers really know its true nature and misconceptions among the public among the public are not of great concern to them.arrow_forwardProvide evidence to support a hypothesis about whether or not the Moon has plate tectonics.arrow_forward
- If all life were destroyed on Earth by a large impact, would new life eventually form to take its place? Explain how conditions would have to change for life to start again on our planet.arrow_forwardThe iron meteorite that created Barringer Crater (Arizona) was 50 m in diameter. It caused a crater 1.2 km (1200 m) in diameter, that is, 24 times bigger than the impactor. Keeping in mind that the size of the crater depends on many factors, such as the type of rocks present in the area, estimate the approximate size of the impactor that produced Mare Serenitatis.arrow_forward6b) If it is true that asteroids and comets have always been raining down on the moon, then is Clavius a young crater or an old crater? 6c) which neighboring crater is older, Scheiner or Blanchanus? please explain. 6e) Generally speaking, which sides of the crater walls is steeper, inner or outer? 6f) Generally speaking, do the crater floors appear to be above, level with, or below the general level of the regions surrounding the craters? Why is this the case? 6g) Why are crater floors smoother than their surroundings?arrow_forward
- What is impact parameter?arrow_forward5) What is the ratio of the number of asteroid impacts on the moon to the number of impacts on Earth? Assume the asteroids are originally traveling 15 km/s and use the following data. Mass: 5.97x1024 kg Earth, 7.3x1022 kg moon Radius: 6372 km Earth, 1738 km moon Note we count the number of craters on the moon to infer the number of impacts on Earth because many Earth craters have been hidden by erosion.arrow_forwardPlanetary scientists are excited about the possibility that some of the moons in the outer solar system might have a global subsurface ocean of liquid water. It's uncertain whether or not Jupiter's moon Callisto has a subsurface ocean, but some scientists think it might. Let's imagine that a short distance below the surface, Callisto has a water layer 20,000 meters thick. Callisto has a radius of 2.410x106 meters. Earth has a radius of 6.378x106 meters, and its oceans are equivalent to a layer of water 3000 meters thick all over the surface of the planet. Which of the following is an accurate comparison of the Earth’s amount of liquid water with this estimate of the amount of water Callisto might have? Group of answer choices If this scenario is correct, Earth and Callisto have roughly the same amount of liquid water. If these scientists are right, Callisto has about one-sixth as much liquid water as the Earth does. If these scientists are right, Callisto has about 11 times as…arrow_forward
- Pluto’s density is 1.8 g/cm 3. This implies that Pluto a. has a large iron-nickel core. b. is about 50 percent water and 50 percent rocky material. c. should have a magnetic field about one-third as strong as Earth’s. d. is still geologically active. e. probably has a small ring system that hasn’t yet been detected.arrow_forwardBased on the physical aspects of Catena Mendeleev, what is the most plausible explanation for how crater chains are formed on the Moon? a. these craters chains are formed by a series of impacts from a passing comet or asteroid that just passed to close too the Moon and ended up colliding with the Moon b. they are the result of surface collapse due to the prescence of an underground fault c. they are primarily the result of secondary fragments hitting the lunar surface from an initially from an larger impact fragment that resulted in another larger, distant craterarrow_forwardIf you'd looked up at the sky when the material from the impact site was re-entering the Earth's atmosphere, what would the sky have looked like? a The normal blue appearance of the sky b A purple glow c The greenish color of the aurora d Red-hot lavaarrow_forward
