Lasted for millions of years: World's longest rainfall

Around 200-300 million years ago, during the dominance of the single supercontinent Pangea, an incredible period of rain occurred. This rainfall continued for 2 million years...

IT BEGAN IN THE DINOSAUR ERA

This period of rain coincided with the time when dinosaurs began to thrive on Earth. This was followed by a very dry period, which was then succeeded by an unprecedented level of rain that lasted for an incredibly long time. Known as the Carnian Pluvial Event, it was first discovered by scientists in the 1970s.

During that time, experts encountered accumulated layers in rocks dating back 232-4 million years and determined that the beginning of the dinosaurs' era on Earth was marked by an incredibly wet period.

LED TO THE FORMATION OF THE ATMOSPHERE

Experts later attempted to determine exactly why it rained continuously for two million years and concluded that it could have been caused by a massive volcanic eruption in the Wrangellia Large Igneous Province. This led to the warming of the oceans, which released moisture into the atmosphere, resulting in increased rainfall.
