vulcanism

Scientists have noticed that global precipitation tends to drop after a volcanic eruption, but they haven't known all the factors that can influence this effect. Now, thanks to a new study, a group of researchers thinks the missing link is El Niño, the weather pattern we normally see every 2 to 7 years.

The surface of Venus is dotted with ring-like structures named coronae, produced by volcanic activity. They appear to be much like the Hawaiian islands on Earth, which are products of volcanic activity from a plume of hot material welling up from Earth’s mantle.
