This image of the volcano sapas mons on venus is based on images taken by the soviet spacecraft venera 13 and venera 14. which of these events explains the presence of the volcano?

First, since the atmosphere is mostly co2, venus has an extreme greenhouse effect. in fact, the surface temperature on venus is about 470! c (about 880! f). further, the surface air pressure on venus is about 90 times greater than that at sealevel on earth. this is roughly equivalent to the water pressure on earth one kilometer beneath the oceanus surface. these surface conditions have two effects. (1) there is no water on the surface of venus. indeed, there is almost no water in the air, either. the clouds are mostly made of sulfuric acid and they are much, much higher than most clouds on the earth. (2) due to the high atmospheric pressure, the winds on venus are also relatively slow. thus, neither wind nor rain can really affect the surface on venus. as a result, volcanic features will look freshly formed for a long time.
