Earth Quote by David Grinspoon
“The reason you see so many volcanoes on Venus is partly due to the fact that there's virtually no erosion there. So on Venus, you're seeing features, some of which are hundreds of millions of years old on the surface. On Earth, we do not see any surface features nearly that old - you only see much more recent features.”
![“We haven't seen a real volcanic event at least in 74,000 years - [Mount Toba] in Indonesia, in Sumatra, where the crater itself is 100 kilometers across. It was so monumental, what happened, that for a very long time the entire atmosphere of our planet was darkened. It's not the lava and the heat…” quote by Werner Herzog](https://sms4smile.com/quotes/img-quotes/826/werner-herzog-964_atmosphere_we-haven-t-seen-a-real-volcanic-event-at_685425.jpg)
