Question: The current and most scientifically accurate theory for the formation of the Moon is:
a.) The large impact theory.
b.) The capture theory.
c.) The fission theory.
d.) The twin formation theory.
Based 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 crater
Describe two theories that explain how the Moon formed?

- Outline the main events in the Moon’s geological history.arrow_forwardWhy are the lunar mountains smooth and rounded rather than having sharp, pointed peaks? A. Because a sheet of ice once covered the moon’s surface billions of years ago. B. Because they rose up from beneath the Moon’s surface due to an increase in pressure from its hot core billions of years ago C. Because micro meteorites impacts have caused their gradual erosion D. Because the moon once had sulfuric acid clouds long agoarrow_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
- Why would you include the Moon in a comparison of the Terrestrial planets?arrow_forwardAt the end of the section on the lunar surface, your authors say that lunar night and day each last about two Earth weeks. After looking over the information in Earth, Moon, and Sky and this chapter about the motions of the Moon, can you explain why? (It helps to draw a diagram for yourself.)arrow_forwardSummarize the four main hypotheses for the origin of the Moon.arrow_forward
- The lunar highlands have about ten times more craters in a given area than do the maria. Does this mean that the highlands are 10 times older? Explain your reasoning.arrow_forwardDescribe evidence of crustal movement (horizontal or vertical) on Mars.arrow_forwardWe believe that chains of comet fragments like Comet Shoemaker-Levy 9’s have collided not only with the jovian planets, but occasionally with their moons. What sort of features would you look for on the outer planet moons to find evidence of such collisions? (As an extra bonus, can you find any images of such features on a moon like Callisto? You can use an online site of planetary images, such as the Planetary Photojournal, at photojournal.jpl.nasa.gov.)arrow_forward
- What is the composition of the Moon, and how does it compare to the composition of Earth? Of Mercury?arrow_forwardWhat is the orbital period of a comet nucleus in the Oort cloud? What is its orbital velocity? (Hints. Use Kepler’s third law in Chapter 4, section 3. The circumference of a circular orbit is 2r . Refer to the text for typical Oort cloud object distances from the Sun.)arrow_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_forward
