Explain how crater counts tell us the age of a surface.
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

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.arrow_forward
