Mars Versus Earth
Mars VS Earth
Mars and Earth are both part of the four terrestrial planets that orbit within the inner solar system and are from the same origin. They are both made of rock and metal. Mars has an extremely weak magnetosphere however, so probably doesn’t have a liquid metal core. Earth on the other hand does have a liquid metal core, which provides its strong magnetosphere. Solar radiation can therefore directly penetrate Mars, while Earth can reflect solar radiation. Mars is much further from the sun than Earth making it much colder. This distance from the Sun also makes a big difference in the length of their years, with Mars year being about twice as long. Further, Mars orbit around the sun is more eccentric than Earth’s, which leads to greater variations in temperature and solar constants overall. The temperatures of their seasons vary greatly and the seasons last much longer. Interestingly the length of their days are almost identical.
Mars has no liquid water on its surface because its atmospheric pressure is too low. Instead the surface only looks similar to places like California’s Mohave Desert and different volcanic places in the Hawaiian islands. Its surface looks reddish from iron oxide, is mostly rocky and barren with no signs of organisms yet, and its air is mostly carbon dioxide. It also has massive dust storms. The only place there might be water is trapped in its polar ice caps. Earth on the other hand abounds with vegetation, life, water, and oxygen due to our atmosphere and relative distance to the sun. Mars is also about half the size of Earth, and its mass is much smaller, making its gravity much weaker as well. Mars does not have plate tectonics like Earth. Because it’s mantle stays fixed, hotspots remain in the same position which is why it develops the largest volcanoes in the solar system, such as Olympus Mons. Earth’s unique position in the solar system and its unique material composition gave rise to its abounding report for
