Some surfaces have experienced more recent geological activity (like volcanism or erosion) that wiped out previously existing craters. They are referred to as "geologically younger" than surfaces that have not experienced activity. We can therefore use crater counts to determine the "age" of a surface, approximating how long ago the last geological event occurred in that area. Using this technique (and assuming these pictures are representative of the crater density on the entire planet), rank the planets in order of their geological age, from oldest to youngest.

If you could drill a hole straight to the center of the earth, and keep track of what the hole is going through, youwould find: a) you would go through one sort of material, and then a different, denser material, and then a still-different, still-denser material, because the planet is made of concentric layers, sort of like an onion.b) you would go through one sort of material all the way to the center, because the planet is all mixed up.c) if your hole started at the north pole, you would go through different layers of different materials, but ifyour hole started at the equator, you would go through one sort of material all the way to the center.d) if your hole started at the equator, you would go through different layers of different materials, but if yourhole started at the north pole, you would go through one sort of material all the way to the center.e) you would strike diet pepsi when you got to the center.
