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.
Why are the atmospheres of Venus and Mars mostly carbon dioxide?
Assume that Venus has an isothermal atmosphere with a surface temperature of 750 K. The surface pressure of Venus
is 90 times the Earth's surface pressure which is about 1013mb. Also assume that the carbon dioxide dominant
atmosphere of Venus is photodissociated and oxygen atoms are produced. These oxygen atoms stop the solar wind
at the ionopause distance where the atmospheric pressure of Venus and the dynamic pressure of the solar wind are
in balance. Accordingly, calculate the lonopause distance of the planet Venus if the solar wind density is 7 #/cm² and
solar wind speed is 410 km/sec.
