However, the flake tectonic activity that occurs on Venus is not the same as plate tectonics, and doesn't involve the recycling of the Venetian surface. This means that although many signs of cratering have been erased over the years, there's still a lot left.

This is to be expected: Earth is the largest, and the most geologically active of the planets. This geologic activity has erased most signs of cratering. Moreover, Earth has very active weather; rain and wind have removed many signs of cratering, AND most of Earth's surface is covered by water. Craters that form underwater don't last very long!","type":"correct","color":"#ffffff","code":"[{\"shape\":\"rect\",\"coords\":\"207,2,322,80\"}]"} {"title":"mars","description":"Mars and Mercury are fairly small, and they cooled fairly fast.

In it's early period, it had a great deal of water in its atmosphere, which increased Venusian temperature, which evaporated more water to vapor, which made it hotter.... until all of the water had evaporated, and either combined with sulfur compounds to make sulfuric acid....or broke apart due to radiation.
