Going back to Figures 3 and 4, Mercury’s surface appears very detailed in these photos. Not so for Venus.
What could be the cause of Venus’ fuzzy appearance?
Step by step
Solved in 4 steps
- Mars has the largest volcanoes in the solar system. (T/F)Astronomers solved this puzzle when they observed a rare transit of Venus in front of the Sun (Figure 5). What could they learn about the planet’s atmosphere from this photo?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.
- Phobos, one of Mars’ moons, is very slowly spiraling down towards the planet. Do you think that Mars will one day have rings? Explain your reasoning,Why is Mars red?Assume that a planet will have lost its initial atmosphere by the present time if the average molecular speed exceeds one-sixth of the escape speed. What would Mercury's mass have to be in order for it to still have a nitrogen atmosphere? The molecular weight of nitrogen is 28.
