Using Jupiter's axial tilt, explain why its rings are harder to observe from Earth than even the dark rings of Uranus
What will be an ideal response?
Like Saturn, the rings of Uranus can appear at a variety of tilts. But Jupiter has only a 5 degree axial tilt, so its rings are seen almost edge-on all the time.

One reason the planets near the Sun are composed mainly of rock and iron may be that
A. the Sun is made mostly of iron, so the planets nearest it are formed of iron. B. the Sun's heat made it difficult for ices and gases to condense near it. C. the Sun's gravity sucked in iron and heavy material and the lighter materials floated farther away. D. the Sun's magnetic field attracted all the iron into the region around the Sun.
