Go to the home page for NASA’s Mars Exploration Program, and look for the latest evidence concerning recent water flows on Mars.
Write a few paragraphs describing the new evidence and what it tells us about the planet’s past.
Evidence exists that Mars may have had oceans 0.500 km deep in its early
history. We don't know what the atmospheric pressure on Mars was back then,
but some studies suggest it may have been as high as 50,000 Pa. What would
have been the highest pressure at the bottom of these oceans? Density of water
is 1000 kg/m³, gmars = 3.71 m/s².
CO2 and planetary warming: understanding Earth’s complicated atmosphere Mars has an atmospheric pressure of 6 mbar (compared with Earth atmosphere pressure of 1013 mbar), 96% of which is CO2. The average calculated temperature of Mars is -57°C, whereas the actual average temperature is -55°C so that the amount of warming due to CO2 is only 2°C. On the other hand, the average calculated temperature of Earth, with 0.4 mbar of CO2, is -19°C, whereas the actual average temperature is 15°C so that the amount of warming due to CO2 is 34°C, much greater than that on Mars, which has higher CO2 concentration. Explain how this is possible.
