Uplands are centers of intense volcanism. Ishtar Terra is the largest. Radar imaging reveals a number of interesting features seen only on Venus. Coronae consist of concentric ridges. The image of Onatah and Bahet coronae is from JPL, and is accompanied by this linked caption .
Impact craters are rare, but they are found.
Dickinson crater is an example. On the other hand the density and pressure are much higher than that of Earth's atmosphere, by a factor of about 90. The amount of sunlight reaching the ground is less that that reaching the surface of the Earth. In spite of this reduced heat input, the surface temperature of Venus is higher than that of the Earth. Both the composition and the total amount of gas add to the green house effect.
