Quizplus · Accepted Answer

The sulfur compounds detected in the clouds above the surface of Venus are most likely to have come from recent eruptions of volcanoes on the planet. As per the observations, the sulfur dioxide (SO2) concentration increases to high levels in the upper cloud layer of the Venusian atmosphere. This indicates the presence of active volcanism spewing gases and dust high into the atmosphere.
