Areography, also known as the geography of Mars, is a subfield of planetary science that entails the delineation and characterization of regions on Mars. [ 1 ] [ 2 ] [ 3 ] Areography is mainly focused on what is called physical geography on Earth; that is the distribution of physical features across Mars and their cartographic representations.

Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. [2]
The above equation describes the Earth's gravitational potential, not the geoid itself, at location ,,, the co-ordinate being the geocentric radius, i.e., distance from the Earth's centre. The geoid is a particular equipotential surface, [ 27 ] and is somewhat involved to compute.
The northern part is an enormous topographic depression. About one-third of the surface (mostly in the northern hemisphere) lies 3–6 km lower in elevation than the southern two-thirds. This is a first-order relief feature on par with the elevation difference between Earth's continents and ocean basins. [12]
Tub Winner: Tru Whip. Tru Whip delivered a fine balance between flavor and texture. It's pleasantly sweet, and with a subtle hint of vanilla, its flavors aren't too overwhelming but also aren't ...
Each week during the 2024-25 NBA season, we will take a deeper dive into some of the league’s biggest storylines in an attempt to determine whether trends are based more in fact or fiction ...
Abyssal plains cover more than 33% of the ocean floor (about 23% of Earth's surface), [2] but they are poorly preserved in the sedimentary record because they tend to be consumed by the subduction process. [1] [3] [4] The abyssal plain is formed when the lower oceanic crust is melted and forced upwards by the asthenosphere layer of the upper ...
