What is thought to be the reason that there are no small impact craters on Mars?
A)Like Venus, Mars's atmosphere is too thick and these meteorites do not survive to makeimpacts on the surface.
B)The surface of Mars is too young to have impact craters.
C)Due to the gravitational pull of Mars's moons, most small meteoroids are deflected and nevermake it to the surface.
D)The wind blows small dust particles, eroding the surface of Mars, erasing small impact cratersfaster than they can form.
E)None of the above. Mars has lots of small impact craters.

The wind on Mars blows small dust particles, eroding the surface and erasing small impact craters faster than they can form. Therefore, there are few small impact craters on Mars. The wind on Mars blows small dust particles, eroding the surface and erasing small impact craters faster than they can form. This phenomenon is known as "wind erosion" and is believed to be the reason why there are no small impact craters on the surface of Mars.
