ASTR 5 Chapter Notes - Chapter 8: Tharsis, Arctic Methane Emissions, Martian Meteorite
Document Summary
Mars is so cold that any liquid water would immediately freeze into ice. The air pressure is so low, that even when the temperature rises above zero, liquid water would quickly evaporate. Describe major seasonal changes that occur in mars. The martian year is nearly twice as long as an earth year each season lasts nearly twice as long on mars. Mars"s seasons are affected by the ellipticity of its orbit: mars"s southern hemisphere has more extreme seasons (shorter and warmer summers, longer and colder winters) than its northern hemisphere. Seasonal changes in mars: northern hemisphere summer: long & cold. Winter: long and frigid: give a brief overview of the geography and major features of mars. Mars is about half as large in diameter as earth (1/4 surface area of earth). Almost the same total land area of earth. Its southern hemisphere has relatively high elevation and its scarred by numerous large impact craters.
