Question 8 a) Its strange tilt produces extreme seasonal variations. b) With its tilt of 29°, Uranus has four seasons similar to those on Earth. c) It never shows any weather in its bland clouds. d) It spins so fast all seasons are the same. Which of these is TRUE about the seasons on Uranus?

Question 2 a) a low-density gaseous core. b) large magnetic fields. c) lots of hydrogen & helium gas. d) many moons. e) differential rotation. Jovian planets share all of the following traits EXCEPT
Question 2 a) a low-density gaseous core. b) large magnetic fields. c) lots of hydrogen & helium gas. d) many moons. e) differential rotation. Jovian planets share all of the following traits EXCEPT All of the jovian planets have dense, compact cores more massive than Earth, surrounded by liquid and gaseous layers.
Question 1 • have liquid metallic hydrogen in their interiors. • have rings. • emit more energy than they absorb from the Sun. • rotate very rapidly. • All of the above. Both Jupiter and Saturn

Question 6 a) Saturn is still radiating heat left over from its formation. b) Saturn’s thick cloud layer contributes to a larger greenhouse effect. c) helium rain gives off heat as it falls toward Saturn’s center. d) Saturn’s atmosphere contains methane. e) Saturn can fuse hydrogen into helium in its core, like the Sun. Saturn radiates even more excess energy than Jupiter because

Saturn radiates even more excess energy than Jupiter because Jupiter and Neptune also radiate excess heat, most likely left over from their formation.
Question 9 a) Jupiter and Neptune b) Jupiter and Saturn c) Jupiter and Earth d) Saturn and Earth e) Uranus and Neptune The magnetic fields of which two planets are most unusual?
Question 9 a) Jupiter and Neptune b) Jupiter and Saturn c) Jupiter and Earth d) Saturn and Earth e) Uranus and Neptune The magnetic fields of which two planets are most unusual? Both Uranus and Neptune have fields that are off-center, and very inclined to their rotation axes.
