COMPLETE ANSWERS [ GRADED A+]
Which is the correct sequence of planets, based on increasing average
radius of their orbits? - ✔✔Closest to Sun
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
,Neptune
Pluto
Farthest from Sun
Which of the following correctly finish the following statement
The inner planets __________.
-have about the same size as the outer planets
-all have several moons
-have about the same composition as the outer planets
-all have orbiting systems of rings
- None of the above - ✔✔None of the above
,The outer planets are hydrogen-helium mixtures, larger than the inner
planets, and have rings and moons. They contrast with the inner
planets in each of these aspects.
Which statement is true for the outer planets of our solar system?
-they produce enough internal energy to glow like the Sun
-they have solid surfaces just below a layer of clouds
-they lack systems of rings.
-they are largely made of hydrogen and helium. - ✔✔They are largely
made of hydrogen and helium.
The giant outer planets are not large enough to sustain nuclear fusion
like stars, but they are made of similar materials - hydrogen and helium.
They have no solid surfaces and they commonly have rings.
, Water ice is __________ on the moons of the outer planets. - ✔✔most
abundant on the moons of the outer planets
Water ice is stable and common on the moons of the outer planets and
into the Kuiper belt. It is unstable in the near vacuum of the inner solar
system because the temperature is too high.
What sets the composition of the moons of the outer planets apart
from the inner planets?
-The moons of the outer planets have abundant hydrogen and helium --
like the planets around which they revolve.
-The moons of the outer planets are dominated by nitrogen ice.
-The moons of the outer planets generally have more iron metal and
are denser than those of the inner planets.
