Which of the following is least reasonable regarding impact craters?
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 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 and produce craters that can be approximately 20 times larger in diameter than the impacting objects.
The faster the incoming impactor, the larger the crater.
The Moon has more craters than the Earth because of its strong tidal force on the impactors.
The least reasonable statement regarding impact craters is:
"The Moon has more craters than the Earth because of its strong tidal force on the impactors."
This statement is not accurate because the Moon does have more craters than the Earth, but the reason for this is not solely because of its strong tidal force on impactors. The primary reason for the Moon having more craters is that it lacks an atmosphere to burn up or significantly slow down incoming objects, whereas Earth's atmosphere provides some protection from smaller impactors.
