- Not including technology and instruments, give 2 reasons why our knowledge of the solar system has increased considerably in the past few years.Explain why a massive, cool planet is more likely to have a thick atmosphere than is a less massive, hot planet.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.
- If there was a planet orbiting a first generation star, which planet in our solar system would it resemble most? Would it be likely for such a planet to have life?equattion : S/4 (1- a) = f*sigma*TS4 Solar Constant (W/m2) S = 1361 How sensitive is the temperature of the earth to changes in the atmospheric transmissivity (f)? The atmosphere is more transmissive (lets more radiation through) when CO2 and other greenhouse gases are lower. During the pre-industrial period, transmissivity (f) was probably around 62% (f = 0.62) and has been decreasing. Calculate how much the Earth's surface temperature would change if the transmissivity changes by ±0.01 (to 0.60 or to 0.62). ___ °C per 1% transmissivity change.Out of the inner planets in the solar system (Mercury, Venus and Mar) which do you think is the most likely to be colonized? Explain why?
