Southern hemisphere has more extreme seasons (shorter and warmer summers, longer and colder winters) than northern hemisphere because planet orbits faster when its closer to the sun: dust devils, swirling winds that are similar to winds over desert sands, like tornados except they rise up from the ground, popular during the summer. Map of mars: half as large in diameter as earth, surface area that of earth, southern hemisphere, relatively high elevation, scarred by numerous large impact craters, northern hemisphere, plains.
