The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It emphasizes the composition, structure, history, and physical processes that shape the planet.
The variation in Mars's surface water content is strongly coupled to the evolution of its atmosphere and may have been marked by several key stages. Head and others put together a detailed history of water on Mars and presented it in March, 2023. [300] Dry channels near Warrego Valles.
Geology of Mars – Scientific study of the surface, crust, and interior of the planet Mars; Geysers on Mars – Putative CO2 gas and dust eruptions on Mars; Glacier – Persistent body of ice that moves downhill under its own weight; Glaciers on Mars – Extraterrestrial bodies of ice; Groundwater on Mars – Water held in permeable ground
A new analysis of data collected by NASA’s InSight mission suggests there may be enough water beneath the surface of Mars to cover the planet. ... and understanding the water cycle of a planet ...
The layering is believed to have come from the global warming and cooling cycle on Mars; during cooling periods, water migrated to the poles and formed the ice-water layers, while on subsequent warming, the unthawed ice water was covered by layers of dust and dirt from windstorms on the surface, helping to preserve the ice water.

T ime was, Earth may not have been the solar system’s only garden planet. For its first billion or so years, Mars was partly covered in water, as dry ocean basins and riverbeds on its surface ...
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
The current Venusian atmosphere has only ~200 mg/kg H 2 O(g) in its atmosphere and the pressure and temperature regime makes water unstable on its surface. Nevertheless, assuming that early Venus's H 2 O had a ratio between deuterium (heavy hydrogen, 2H) and hydrogen (1H) similar to Earth's Vienna Standard Mean Ocean Water of 1.6×10 −4, [7] the current D/H ratio in the Venusian atmosphere ...
