First Rain On Earth: When there was a terrible drought on the earth and then it rained for 20 lakh years, know what the reason
When it rained continuously on the earth for 20 lakh years
First Rain On Earth: Record-breaking heat is being experienced in many countries of the world including India. The heat in the country's capital Delhi has broken the record of 12 years. People in many states are waiting for monsoons and rain. But, there was a time when it rained continuously on the earth for millions of years. Millions of years of rain helped in the origin of life on this planet. Scientists are still trying to understand this mystery of why and how it happened.
According to scientists, 20 to 30 crore years ago the earth was completely different. It was just one place and there were no different continents. Scientists believe that at one time it rained continuously on the earth for 10 to 20 lakh years. Geologists discovered such layers in some ancient rocks in the 1970s and 80s, which were unusual. These ancient rocks were about 230 million years old.
One team of researchers studied a layer of siliciclastic sedimentation in the Eastern Alps. This layer of sedimentation was deposited within carbonate structures. Another team analyzed a layer of gray rock embedded inside the famous red rock in Britain.
These two findings and other studies from different parts of the world revealed a similar concept. At one time in the history of the Earth, there was a long period of drought and then the rain started. Geologists concluded that the Earth was unusually wet at the beginning of the dinosaur era. This period is known as the Carnian Pluvial Event or Carnian Pluvial Episode.
This interesting event that happened on Earth led to the need to understand why it started raining for millions of years. Scientists believe that the moisture level increased significantly due to the increase in humidity, which was probably caused by large-scale volcanic eruptions in the Wrangellia Large Igneous Province.
Due to this, it rained continuously on Earth for millions of years. This event probably increased the temperature of the Earth. The result was that the oceans became warmer and the amount of moisture in the atmosphere increased. A study was published in the Journal of the Geological Society. It showed that the humid period was beneficial for dinosaurs. This period of increased moisture after a tumultuous era with frequent volcanic eruptions helped in diversification.
