- Describe sources and sinks of CO2, if any, on Venus today.arrow_forwardThe runaway greenhouse effect and its inverse, the runaway refrigerator effect, have led to harsh, uninhabitable conditions on Venus and Mars. Does the greenhouse effect always cause climate changes leading to loss of water and life? Give a reason for your answer.arrow_forwardLook at Figure 21-11. Which molecule(s) can escape from Earths gravity? From Mars? From Venus? Figure 21-11 Loss of atmospheric gases. Dots represent the escape velocity and temperature of various Solar System bodies. The lines represent the typical highest velocities of molecules of various masses. The Jovian planets have high escape velocities and can hold onto even the lowest-mass molecules. Mars can hold only the more massive molecules, and the Moon has such a low escape velocity that even massive molecules can escape.arrow_forward
- Describe two anomalous features of the rotation of Venus and what might account for them.arrow_forwardAtmospheric jet streams on Venus travel at about 300 km/hr. How long does it take a jet stream to circle the planet once? How many times does the jet stream circle the planet during one solar rotation of the planet? (Notes: The circumference of a sphere is c = d, where d is diameter. The diameter and solar rotation period of Venus are given in Celestial Profile: Venus.)arrow_forwardWhy do small planets cool faster than large planets? Choose any two of the five Terrestrial worlds and calculate for each one the ratio of its surface area to its volume. Why is this ratio important? (Hint: Does this ratio have anything to do with the ability of a planet to lose internal heat?) (Note: The surface area of a sphere is 4r2, and the volume of a sphere is 43r3.)arrow_forward
- Look at Figure 21-1. Compare temperature profiles of Venuss and Earths atmospheres. Describe the differences between the two profiles. Figure 21-1 (a) Image of Venus made from an approaching spacecraft using a UV filter designed to bring out small contrast differences in the clouds that completely hide the planets surface. None of these details would be visible to an unaided human eye. (b) The four main cloud layers in the atmosphere of Venus are more than ten times higher above the surface than ordinary Earth clouds. If you could insert thermometers into Venuss atmosphere at different levels, you would find that the lower atmosphere is much hotter than that of Earth, as indicated by the red line in the graph, but temperatures in the two planets upper atmospheres are quite similar.arrow_forwardDescribe and explain changes in Venuss surface temperature during the planets history.arrow_forwardThe water clouds believed to be present on Jupiter and Saturn exist at temperatures and pressures similar to those in the clouds of the terrestrial atmosphere. What would it be like to visit such a location on Jupiter or Saturn? In what ways would the environment differ from that in the clouds of Earth?arrow_forward
- 1arrow_forwardAssuming all other variables were earth based besides atmospheric pressure, calculate the temperature at which water would boil at sea level on Titan versus Earth? And explain why using molecular concepts. Consider the pressure of Earth’s atmosphere at sea level to be 1 atm and the pressure of Titan’s atmosphere at sea level to be 1.45 atm. ps plz stop refusing my questions or im going to cancel this membershiparrow_forwardGiven what you've learned about the solar nebula idea, what do you believe the likelihood is of discovering livable planets in other solar systems?
