Scientists: the river and the sea, once existed on Mars, could arise due to volcanoes - ITAR-TASS

NEW YORK, November 25. / ITAR-TASS /. Rivers and seas once existed on Mars, there arose due to the high concentration of greenhouse gases in the atmosphere. With this assumption made by scientists at the University of Pennsylvania. In an article published in the latest issue of the journal Nature, they announced the unraveling the mysteries of the Red Planet.

According to their proposed version, about 4 billion years ago, Mars was enveloped in a dense veil of hydrogen and carbon dioxide, so the temperature and humidity on the surface were much higher than now. This created favorable conditions for the existence of rivers, seas and even oceans, which now resemble a parched riverbed and deserts.

“This is a very exciting discovery because scientists for 30 years scratching their heads over how the climate of Mars could be so warm and humid that there could produce large bodies of water,” – said one of the authors of a new hypothesis Ramses Ramirez. Same source of greenhouse gases, according to Ramirez and his colleagues served as active at the time of the Martian volcanic activity.
