Despite being within the sun’s “habitable zone”, both Venus and Mars have average surface temperatures that do not permit the existence of liquid water. Besides albedo, name three other important properties of a planet that can influence its temperature.
Which of the following properties of Mars would be altered by the process of terraforming?
its size
its atmospheric chemistry
its distance from the Sun
its geological activity
its magnetic field
Even if we were to terraform Mars to give it an Earthlike climate, that climate would not be as stable as Earth's, due to Mars's lack of
a large moon
volcanic activity
an iron core
atmospheric nitrogen
What is the escape velocity is km/s from Venus' exosphere, which begins about 202 km above the surface ? Assume the gravitational constant is G= 6.67 x10-11m3 kg-1s-2, and that's Venus has a mass of 5.2e+24 kg and a radius of 6500.0 km
