in section 24-2, you learned how neptune is different from uranus, and how its rings and moons formed and evolved. based on what you learned about uranus, select all of the correct statements from the following list. neptune's position was predicted before it was discovered. neptune's largest moon, triton, has a retrograde orbit, which suggests that it was captured. like uranus, neptune shows very little atmospheric activity.

Respuesta :

Appropriate Phrases:

  1. The size, mass, composition, and internal structure of Neptune are comparable to those of Uranus.
  2. Triton, Neptune's biggest moon, has a retrograde orbit that suggests it was taken captive.
  3. There may be geological activity on Triton, which has a thin atmosphere.
  4. Before it was actually found, Neptune's position was predicted.

Does Neptune contains only water?

In the outer solar system, Neptune is one of only two ice giants (the other is Uranus). Water, methane, and ammonia make up the majority (80% or more) of the planet's mass, which is made up of a hot, dense fluid above a tiny, rocky core. Reasons:-The twin of Neptune is Uranus. Their compositions and masses are comparable. They have a rocky outer layer, a mantle made of a mixture of water, ammonia, and methane ices, and a core made of a combination of rock and ice. Methane, helium, and hydrogen make up the atmosphere.2.7 times more energy is emitted by Neptune than it takes in from the Sun. Storms, which do not exist on Uranus, are produced in its atmosphere by this excess energy. There is no internal energy source on Uranus. Triton orbits Neptune in the opposite direction from how Neptune rotates. Some theorize that it might have formed somewhere else before being drawn in by Neptune's gravity. Neptune emits more energy than it takes in from the Sun because, unlike Uranus, it seems to have an internal heat source. The atmosphere of Triton is relatively thin and primarily made up of nitrogen with a trace amount of methane. It is also geologically active, with a young surface, a dearth of impact craters, active gysers, etc. With the help of convection, magnetic dynamos in their cores produce magnetic fields, which are present on both Uranus and Neptune. Their magnetic field is significantly stronger than Earth's. Urbain Jean Leverrier first provided the calculation for the predicted position before it was discovered.
