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.
