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.
Hellas 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.
5) 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.

It caused a crater 1.2 km (1200 m) in diameter, that is, 24 times bigger than the impactor.
