Heavy Rain Carved Complex Network Of Valleys On Mars 3.8 Billion Years Ago

Heavy bouts of rain may have frequently punctuated Mars' early climate، as evidenced by the complex network of valleys slithering their way through the Martian ground، as Technical Times said.
New findings by a team of researchers show that the deep channels on the surface of the Red Planet may have been carved into place by rainfall nearly 4 billion years ago.
The research draws upon earlier studies done on similar geographic structures on Earth that show the terrestrial channels were caused by huge streams of rainwater.
Scientists have long known that Mars harbors an intricate web of deep valleys، some going as wide as 12 miles and plunging almost as deep as 3،000 feet. These valleys branch out from each other، much like the tributaries of a great river splitting off from the main channel.

The discovery led experts to assume that Mars must have had enough water to sculpt the valleys into the Martian soil. However، where the water that created these channels came from has remained a mystery.

Some theories point to a large body of water، such as a lake، that must have been there once while others believe it could be water emerging from the ground. Yet other scientists think it could be from the melting ice on Martian highlands caused by heat coming from the volcanoes.
