The researchers say this indicates an upper crust made of a mixture of rock and ice — in which
small craters could be carved — supported by a more viscous mantle of ice lower down, which would allow the biggest impact basins to relax away with time, like silly putty returning to its original shape.

An exception to this may have been if you used a lightweight and / or hollow object that did not sink at least halfway into the layer of flour — if this happened, a relatively
smaller crater may have formed because the part of the object that hit the flour was smaller in diameter than the object's actual, widest diameter.
The smallest craters should have been made by the smallest object, and the largest craters should have been made by the largest object.

small craters, he adds, then they're well worth the search.

small craters with relatively fresh - appearing impact ejecta.
Secondary craters form when big chunks of rock blasted into the air during a large impact fall back to the surface, leaving a smattering of

small craters next to Kokopelli Crater, seen at bottom right in this image, on dwarf planet Ceres.
This image taken by NASA's Dawn spacecraft presents two
small craters on Ceres, located in the vicinity of Toharu Crater.
There are
no small craters because small meteoroids burn up in the dense atmosphere before reaching the ground, and the bunching of craters suggest that large meteoroids usually break up before reach the surface.

crater after all.
