Step by step
Solved in 3 steps
- 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?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.Name two factors which determine whether a planet has atmosphere or not.
