Solved in 2 steps
- If the cloud layer of Venus is so thick, how is it possible for any sunlight to reach the surface planet theMars has the largest volcanoes in the solar system. (T/F)Eventually, space telescopes have shown that Venus is shrouded by a very dense atmosphere (see Figure 6). To pierce through the dense clouds and study its surface, astronomers had to use radio imaging (see Figure 7). Venus’ atmosphere is transparent to radio waves. Research and explain briefly how, through radio imaging, Venus’ surface could be reconstructed.
- Why is Mars red?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?(b) Show that the equilibrium temperature of Venus is right for liquid water, given that it lies = 3.85 × 1026 W) and assuming a at a distance of d = 1.09 × 108 km from the Sun (Lo mean albedo of 0.45. Explain why, in reality, Venus is too hot for liquid water.
- Numerous surface features on Venus can be seen in Earth- based images made in the ultraviolet part of the spectrum. (T/F)Out of the inner planets in the solar system (Mercury,Venus and Mars), Which do you think is most likely to be colonized? Explain why?Who knows why Mercury and the Moon have so many more impact craters than our planet. In what way does a surface's number of craters reflect its age?
