信号词为for example,在解释如何通过观察来间接推断出大气层成分的部分,教授通过两个例子进行具体说明:For example,we know its mass and volume,so we are able to calculate its density.Knowing Uranus’density gives us ideas about its chemical makeup,即了解星球的密度可以帮我们了解构成,因此C选项是正确...
The planet Uranus - already an odd duck for its upended rings and spin axis that means it is spinning on its side - is being chased by two asteroids and is chasing another. One of the asteroids is in an unexpected orbit, by some estimatesSpotts, Pete...
The researchers ran computer simulations and found that the most likely cause of Uranus’ tilt is that it was grazed by a large object which pushed the planet over onto its side but did not affect its interior. In the case of Neptune, the planet seems to have been subject to a head-on...
If it was still functioning properly when that was completed, it would be boosted by Saturn’s gravity to visit Uranus and Neptune before also leaving the ecliptic and exiting the solar system. This was considered a long shot, but amazingly, everything worked as planned. Next, what kind of...
