Atmospheric density would be a factor affecting the number of impacts on a planetary body.
No but the sizes of OTHER planets and planetesimals can and do.
cause our tongue is the size of mars
There isn't a typical size planet
While Jupiter is composed mainly of gasses there is a solid core at the center of the planet roughly the same size as the earth. The surface of this core is believed to be composed of glacier ice. Therfore Jupiter does have landforms.
Asteroids, meteorites or comets are impactors that form impact craters on the Earth and other bodies throughout the solar system. Obviously, the Earth for instance, has to cross an impactor's orbit or vice versa. The size of the impactor hitting the Earth depends on the type of crater that can occur and also the other factors- · the velocity of the impactor · composition of the impactor · composition of the target rock · the strength and porosity of the impactor · angle of impact · gravity of the target planet For more on craters try- www.weirdwarp.com
We conclude that something must be renewing or eroding the surface.
Its surface is relatively young and therefore that there are internal mechanisms that are or have been recycling the surface.
Impact craters. The size of the crater is related to the speed of the impact and the size of the object.
By "wholes" I assume you mean craters. Most of the moons craters are caused by meteorite impact of varying size.
Craters occur when flying objects in space crash onto a planet. Then, depending on the size of the crater, a large depression-like hole will form.
Mercury. Both are approx the same size, and both are covered with craters.

Yes. This is because the moon has no atmosphere, bodies such as meteors do not burn up like they do on Earth. Because of this, these bodies hit the moon in their full size and, due both to the size of the body and the speed at which they are moving, they leave craters upon impact.
By studying the depth and diameters of the moon's craters, an impact specialist could determine the size of the object that hit the moon, give a good estimate of the velocity of the object, and approximate where it originated from in the sky.
An atmosphere will lessen both the amount and size of impact craters by burning meteoroids so they get smaller or even disappear entirely. If there is no atmosphere, the object will simply hit the planet or moon with no reduction in its size. Earth's atmosphere does this because the air molecules create friction when the meteoroid passes through it. The friction is hot enough to burn the meteoroid up entirely or at least down in size. An atmosphere means fewer and smaller meteoroids. (When a meteoroid does make it to the ground, it then is called a meteorite.)

depending on the size it could destroy the planet or impact in the water and not do much. It all depends on the size of said asteroid!
