Yes, there is. Specifically, the rain that fell millions of years ago left marks on the volcanic ash masses that, over time, were transformed into rocks that scientists can use today to analyze the atmosphere of the past. Using this novel method, dubbed paleobarometry , scientists at NASA's Ames Research Center have so far been able to calculate the speed and diameter of the raindrops at the moment of impact and deduce, from the data, the density of the air 2.7 billion years ago. Specifically, “fossil rain” analyzes on rocks found in South Africa indicate that the Earth's early atmosphere must have had a high concentration of greenhouse gases .
Does fossil rain exist?
Gravity continues to change the Earth… from within
A new study highlights that, although subtle, the effects of gravity are still echoed in the rise and fall of our planet's upper crust.
What is the temperature of the center of the Earth?
Is the Earth's core hotter than the Sun? The truth is that no, but you will be surprised to know how hot the center of the Earth is.
The asteroid that killed the dinosaurs caused a 'mega-earthquake' that lasted weeks or months
The first global simulation of the Chicxulub crater impact tsunami has determined the trajectory and power of the 66-million-year-old tsunami.
The Earth has an 'ocean' 660 km deep
A diamond has confirmed that there are colossal masses of water equivalent to six times the water of all the oceans) at a depth of 660 km.
Amasia: this is how the next supercontinent will form
What will the Earth look like in the future? On geological time scales, the Earth's continents are continually changing. This is the simulation of what the next supercontinent of the planet will be like.
