Martian dichotomy
The most conspicuous feature of Mars is a sharp contrast, known as the Martian dichotomy , between the Southern hemisphere and the Northern. The two hemispheres' geography differ in elevation by 1 to 3 km. The average thickness of the Martian crust is 45 km, with 32 km in the northern lowlands region, and 58 km in the southern highlands.

The martian crustal dichotomy is the most prominent feature of Martian topography. It is a boundary between the northern and southern hemispheres. The two hemispheres differ in elevation by 1 to 3 km. The average thickness of the Martian crust is 45 km, with 32 km in the northern lowlands region, and 58 km in the southern highlands. This border between the two hemispheres is quite complex in places. One distinctive type of topography is called Fretted terrain . [1] It contains mesas, knobs, and flat-floored valleys having walls about a mile high. Around many of the mesas and knobs are Lobate Debris Aprons that have been shown to be rock covered glaciers. [2] Many large river valleys cut through the dichotomy. [3] [4] [5] |
