An artist's impression of ancient Mars and its oceans based on geological data The blue region of low topography in the Martian northern hemisphere is hypothesized to be the site of a primordial ocean of liquid water. [1] The Mars ocean theory states that nearly a third of the surface of Mars was covered by an ocean of liquid water early in the ...

This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep.
The blue region of low topography in the Martian northern hemisphere is hypothesized to be the site of a primordial ocean of liquid water. [183] The Mars ocean hypothesis proposes that the Vastitas Borealis basin was the site of an ocean of liquid water at least once, [23] and presents evidence that nearly a third of the surface of Mars was ...
The implication here is that a great northern ocean may have existed for millions of years. One argument against an ocean has been the lack of shoreline features. These features may have been washed away by these tsunami events. The parts of Mars studied in this research are Chryse Planitia and northwestern Arabia Terra. These tsunamis affected ...

On Mercury, chaos terrain can be hilly or lineated. An original theory for the formation of chaos terrain on Mercury is an impact basin on the opposite side of the planet. However, there is some terrain on Mercury that has no connections to an impact basin, so this theory doesn’t fully explain Mercury’s chaos terrain. [4]
