WebMentioning: 1 - Ancient Mars likely hosted oceans similar to those on Earth; however, such water is not presently observed on Mars. One possible explanation for the lack of present-day oceans is that surface water was transported into and stored within the interior of Mars throughout the geological history.

WebStrength appears to be concentrated in the crustal upper 7–12 km of the lithosphere. This finding is in very good agreement with the depth distribution of seismicity. Earthquake hypocenters are restricted to the uppermost crustal levels, suggesting that brittle deformation of the lithosphere is limited to depth of 5–15 km ( Tóth et al. , 2002 ).
