Volcanism on mars olympus mons is the largest volcano in the solar system. Tectonic on mars valles marineris is a vast system of canyons. Ice caps! ( mix of carbon dioxide and water ) Ice that is about 3. 5 km thick cover poles of mars (seasonally) Found widely scattered hematite blueberries which on earth, tend to form presence of water. Dark streaks appear when temperature is -10 degree. There are 2 types of naturally occurring hydrogen atoms. Proton in nucleus, electron outside = hydrogen. Proton & neutron in nucleus, electron outside = deuterium (heavy hydrogen) Earth has much more h than d in in its oceans. ( earth has a low d/h ratio ) Lets say earth and mars started off with the same mix of h and d ( the same amount of ratio ) Over time, mars would lose more h than d ( earth lose a tiny bit of both, but more h than d )
