Sulpfur on Venus and Earth — Why the Difference?

Venus has been called Earth's twin. More like "evil twin", because it has extremely hot temperatures (being closer to the sun causes "global warming"), lots of volcanic activity, sulfur dioxide clouds, and atmospheric pressure. The first probes to land on another planet were sent by the former Soviet Union, the Venera program ( Venera 13 sent back the first color pictures from Venus), but they didn't last long in that environment.
