How has cratering played a role in the evolution of the planetary surfaces? - play planetary pinball funbrain

After the formation of planets there are about 4.5 billion years have seen a lot of stuff others were. This material has been shaped rocks of ice, they had different orbits of comets from the Oort cloud. Often cross these lines with the formation of planets and therefore have an impact on the newly formed surfaces with a large amount of kinetic energy.

While the surfaces are melted, these effects are just adding more hardware for the planet (in fact some of the H2 and CO2 in the mantle comet comes early). But as the planet cooled, the crust cooled down first and solidified. Later impacts would have either 1) created craters 2) broke the crust on the exemption from the lava pools, the outer mold. Please note that with time and the planet cools, the crust thickens and forms pools effects are rare. The basins are partly filled with craters.
