Question 2 a) Europa b) Io c) Amalthea d) Ganymede e) Callisto The surface of which jovian moon most resembles the pack ice of the Arctic Ocean?
Question 2 a) Europa b) Io c) Amalthea d) Ganymede e) Callisto The surface of which jovian moon most resembles the pack ice of the Arctic Ocean? Ice-filled surface cracks indicate an ocean may lie below.
Question 3 a) Jupiter’s magnetosphere b) Jupiter’s rapid rotation c) tidal stress from Jupiter and Europa d) radioactive decay from its core e) Io’s large mass and tectonic activity What is thought to cause Io’s volcanism?
Question 3 a) Jupiter’s magnetosphere b) Jupiter’s rapid rotation c) tidal stress from Jupiter and Europa d) radioactive decay from its core e) Io’s large mass and tectonic activity What is thought to cause Io’s volcanism? Io is constantly “squeezed” by its huge neighbor as well as by companion moons, heating its interior.
Question 8 Which moon in the solar system shows a dense atmosphere? a) our Moon b) Phobos c) Europa d) Titan e) Triton
Question 8 Which moon in the solar system shows a dense atmosphere? a) our Moon b) Phobos c) Europa d) Titan e) Triton The Huygens probe, deployed by the Cassini spacecraft in 2005, showed that Titan’s atmosphere has a complex organic chemistry.
Question 5 a) distance from a planet, inside of which a moon can be tidally destroyed. b) density that a moon can have and be solid. c) distance from a planet that a moon can experience synchronous rotation. d) mass a moon can have and still be classified as a moon. The Roche limit is defined as the critical
Question 5 a) distance from a planet, inside of which a moon can be tidally destroyed. b) density that a moon can have and be solid. c) distance from a planet that a moon can experience synchronous rotation. d) mass a moon can have and still be classified as a moon. The Roche limit is defined as the critical Saturn’s rings, as well as those of the other jovian planets, lie within its planet’s Roche limit.
Question 7 a) They are made of frozen metallic hydrogen. b) They contain glassy beads expelled by volcanoes on Enceladus. c) They contain shiny bits of iron. d) Titan and other moons reflect additional glow onto the rings. e) They are made of relatively new ice. Why are the rings of Saturn so bright?
Question 7 a) They are made of frozen metallic hydrogen. b) They contain glassy beads expelled by volcanoes on Enceladus. c) They contain shiny bits of iron. d) Titan and other moons reflect an additional glow onto the rings. e) They are made of relatively new ice. Why are the rings of Saturn so bright? Saturn’s rings are perhaps only 50 million years old, the result of a small moon coming within the planet’s Roche limit.
