This Concept Map, created with IHMC CmapTools, has information related to: GROUP CMAP!!, Ancient Mars may have sustained life because Some life on Earth can survive in extreme, Martian-like conditions (i.e. lychens) provided that there is liquid water, Atmosphere full of dust ???? Dust dangerous to inhale, Mars has canals that look like dried-up river beds these could mean that Earlier temperatures on Mars were high enough to allow water in liquid form, Global temperatures on Mars may have been much higher which could mean that Mars previously had a significant atmosphere to generate adequate greenhouse effect, Micro-organisms may have existed on ancient Mars which can only happen if Water in the liquid form has previously existed on Mars, Geologically inactive therefore Global temperatures on Mars may have been much higher, Shape of Martian geological features suggests occurrence of flash flooding these could mean that Earlier temperatures on Mars were high enough to allow water in liquid form, Mars has Martian meteorites, Existence of water in liquid form in earlier times because Shape of Martian geological features suggests occurrence of flash flooding, Even when storm is over dust particles are so fine they float around for weeks. Becoming Atmosphere full of dust, Dust storms Duration Lasts for months, Thick crust and lower amounts of conductive material in mantle Geologically inactive No recycling of materials, Water in the liquid form has previously existed on Mars and therefore Earlier temperatures on Mars were high enough to allow water in liquid form, Extremely cold temperatures Ice water Cannot exist in liquid form unless global temperatures rise, Dust dangerous to inhale Therfore Uninhabitable, Composition 95% CO2 Uninhabitable, Microscopic structures resembling the shape of fossilised bacterial organisms and so it suggests that Micro-organisms may have existed on ancient Mars, Earlier temperatures on Mars were high enough to allow water in liquid form and hence Ancient Mars may have sustained life, Dust storms Travels Up to 100-200kms/hr, Dust storms Cpmposed of Extremely fine dust particles
