Interestingly, while Mars is about half the diameter of Earth, its surface has nearly the same area as Earth’s dry land. Its volcanoes, impact craters, crustal movement, and atmospheric conditions such as dust storms have altered the landscape of Mars over many years, creating some of the solar system's most interesting topographical features.
13 Οκτ 2014 · Mars shows us a dry, dusty, rocky surface. The southern half of the planet is much more rugged, with many more craters and highlands. The northern half of Mars has more smooth basins and what appear to be dry lakebeds and sinuous riverbeds.
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.
Mars topography. But perhaps most striking of all is the general difference in height and surface roughness between the northern and southern hemispheres. The northern hemisphere is smooth and flat and on average six kilometres lower than the rugged highlands of the south.
