A recent study revealed the discovery of a vast ocean on the surface of Mars about 3.5 billion years ago, but conditions on the surface of the Red Planet have changed due to the factors of time.
The study revealed, according to the images of the spacecraft, the presence of the remains of this ocean in the form of a characteristic beach terrain, determined by numerous satellite images of the surface of Mars.
Ocean researchers mapped more than 6,500 kilometers (4,039 miles) of river ridges, apparently carved by rivers, indicating that they were most likely eroded into river deltas or sea channel belts.
Using data from the Mars Reconnaissance Orbiter collected in 2007, the team applied an analysis of the thicknesses, angles and positions of the ridges to understand the area of study: the topographical depression known as the Aeolis Dorsa region on Mars.
Cardenas says it seems likely that there will be many changes in this part of the planet all these years ago. This is evidenced by the evidence of large sea level rises and the rapid movement of rocks by rivers and streams.
