The magnetosphere is important because it is what sweeps away the solar wind, allowing a body to have an atmosphere. What might have been the most likely effect on the Earth?B) The gravitational pull might have prevented the Earth settling into a stable orbit, which would have prevented the development of life on Earth.Figure 11.6 ("Zonal Flow") in the textbook shows that the most rapid westerly wind flows on Jupiter occur atWhat is a reasonable description of the Great Red Spot?What do the different colors in Jupiter's clouds indicate?D) The depth at which the clouds reside within Jupiter's atmosphereHow does the heat Jupiter radiates compare to the energy it receives from the Sun?A) Jupiter radiates back into space about twice the energy it gets from the Sun.D) the slow escape of gravitational energy released during the planet's formationWhat would Jupiter have needed to have become a star?B) a massive core of rocky materials with some iron mixed inJupiter gives back into space twice the energy it gets from the distant Sun. In Jupiter's case, it is more round than it would be, spinning as rapidly as it does, if it were made only of hydrogen and helium gas; it must have a more solid rocky core deep underneath the fluid clouds.What material makes up most of Jupiter's volume, and why is it not found here? Which statement about that spacecraft is true?The spacecraft's probe measured windspeeds in Jupiter's atmosphere.The belts of Jupiter are best described as follows:regions of downward moving material and low pressure.Together which two gases make up 99% of Jupiter's atmosphere?Alternating zones of rising and sinking gas in Jupiter's atmosphereHow does the heat Jupiter radiates compare to the energy it receives from the Sun?Jupiter radiates back into space about twice the energy it gets from the Sun.What is the source of Jupiter's nonthermal radio radiation?metallic hydrogen swirling in the planet's interiorthe slow escape of gravitational energy released during the planet's formationWhat would Jupiter have needed to have become a star?a massive core of rocky materials with some iron mixed inJupiter gives back into space twice the energy it gets from the distant Sun. Ice particles like Saturn's rings cannot exist to close to hot Jupiter, which gives back into space twice the energy it gets from the Sun.Contrast the compositions of Jupiter's belts and zones. How does the mass of Jupiter compare with that of the other planets?B) It is twice as massive as all other planets combinedHow does the density of Jupiter compare to the terrestrial planets?How was the rotation rate of Jupiter's core determined?A) by radio observations of Jupiter's rapidly spinning magnetosphereWhat evidence do we have that Jupiter must have a substantial solid core under the thick clouds?A) Jupiter's disk is less oblate that it should be, if it were only hydrogen and helium.What is interesting about Jupiter's rotation period?Jupiter is noticeably oblate (flattened) rather than spherical primarily because of which of the following physical effects?A) The equatorial zones rotate in less time than the higher latitudesWhat is the name used to describe the dark bands encircling Jupiter?The most striking "cloudmark" in Jupiter's atmosphere is the:What is the probable source of the day-to-day variations in Jupiter's belts and zones?D) differential rotation and the underlying zonal flowThe reason the jovian planets lost very little of their original atmosphere is due to their:B) regions of downward moving material and low pressureTogether, which two gases make up 99% of Jupiter's atmosphere?Alternating zones of rising and sinking gas in Jupiter's atmosphere:If Jupiter were about 80 times more massive than it is, nuclear fusion should have been possible, making it a small star. (SA)The zones are high, cold regions of ammonia ice crystals, white in color. Jupiter is a huge planet, but its magnetosphere is mind-blowingly massive.
Most of these particles, which are ionized and swept up by the field, come from the volcanic gases spewing from Jupiter’s moon Io. Answer and Explanation: Jupiter?s magnetic field is extremely strong. C) Its magnetic field must be form by rotating molten iron, like our own. It may be in part debris from Io's violent volcanoes, and dust from the breakup of the tiny moons Tethys and Adrastea, both so close to Jupiter they are under great tidal stress. Astronomy Today Ch.
About 5.3 million kilometers (3.3 million miles) wide on average, the magnetosphere is 150 times wider than Jupiter itself and almost 15 times wider than the Sun. What is it made of, and why? (SA)When the comet passed close to Jupiter in 1992, gravitational tidal forces tore the nucleus apart, leaving it in fragments. (SA)Liquid metallic hydrogen can be formed only under tremendous pressure, not found even in the Earth's interior, much less on its surface. Where is this energy coming from, for the most part?E) the slow escape of gravitational energy left from its formationB) It has a tail that extends at least to Saturn's orbitWhat is the source of Jupiter's intense radio waves and magnetism?E) liquid metallic hydrogen swirling in the rapidly spinning mantleCompared to its rotational axis, Jupiter's magnetic field:E) lies about 10 degrees off, much like our own rotation and magnetic fieldD) It is a million times the volume of the Earth's, extending beyond the orbit of SaturnHow does the magnetic tilt of Jupiter compare with our field?E) Both are tilted about 10 degrees, but Jupiter is the opposite in polarity.Which of the Galilean moons is the densest and most geologically active?E) The four Galilean moons formed with Jupiter, most others were later capturesOf the Galilean satellites, which has the oldest, most heavily cratered surface?Which of the jovian moons is the largest and also the largest moon in the solar system, even bigger than Mercury?What is the major component of Io's volcanic flows?Which three Galilean moons were found by Galileo to have weak, changing magnetic fields?In size, from largest to smallest, the correct order for the Galilean moons is:Which of the four Galilean moons is NOT differentiated?The moon of Jupiter most similar in size to Earth's Moon isA) is continually resurfaced with volcanic activityA) A doughnut-shaped region of the energetic heavy ions that follows Io's orbital trackJupiter's moon Europa might harbor life because it has which of the following conditions?C) above Jupiter's cloud tops and inside the orbit of its inner-most moonWhich of the following best describes Jupiter's ring(s)?
