The clouds around Venus contain relatively large droplets ofsulfuric acid, which occasionally rain down on the surface of theplanet, or at least they try to, because the temperature is so high thatthe droplets evaporate before they actually reach the surface. (This“almost rain” is called virga, the term for any kind of precipitationthat evaporates before it reaches the ground.) On Earth, however,the sulfuric acid does not evaporate but falls to the ground as acidrain, an environmental pollutant that can destroy buildings andharm plants and animals
