|
The clearly different size classes of objects in our solar system are: the Sun,
|
the Jovian planets and the Terrestrial planets.
Yes. About a factor of ten difference in sizes. |
014.11
|
|
|
The large objects in our solar system come in
|
in just three size categories, with the Sun as one of them.
Yes. The Jovian planets and the Terrestrial planets are the other two. |
014.12
|
|
|
Within the Solar system, the size ratio between the largest object in one category and the largest object in the next is close to
|
10.
Yes. The Sun is about 10 times the size of Jupiter, which is about 10 times the size of the Earth. |
014.13
|
|
|
The Sun is approximately
|
one hundred times the size of the Earth.
Yes. Ten times the size of Jupiter, which is ten times the size of the Earth. |
014.14

|
The density of water is 1000kg/m3 while the density of iron is 7800kg/m3. Which of the following values is a plausible value for the density of a terrestrial planet?
|
5000kg/m3
Yes. Rock and iron. |
014.21
|
|
|
The density of rock is about 3000kg/m3. The density of the Earth is
|
greater than 3000kg/m3 because the Earth has an iron core.
Yes. A little iron, with a density of 7800kg/m3 adds a lot of mass. |
014.22
|
|
|
Which of the following statements about the moons of terrestrial planets is currently accepted?
|
they sometimes capture moons by accident.
Yes. Mars is one example. Earth is more complicated, but still an accident. |
014.23
|
|
|
Which of the following three systems is regarded as the most normal for a terrestrial planet?
|
Venus, with no moons at all.
Yes. Typically, terrestrial planets do not have moons. |
014.24
|
|
|
The density of water is 1000kg/m3 while the density of rock is 3000kg/m3. Which of the following values is a plausible value for the density of a jovian planet?
|
700kg/m3
Yes. Actually that is the density of Saturn. |
014.31
|
|
|
The density of rock is about 3000kg/m3. The densities of the jovian planets are
|
less than 3000kg/m3 because they are mostly gas.
Yes. Some, like Jupiter, are thought to have rocky cores. |
014.32
|
|
|
The jovian planets typically have
|
large systems of moons.
Yes. Each has a miniature solar system of objects. |
014.33
|
|
|
Asteroids are made of
|
rock and iron.
Yes. Some asteroids are rock, some are iron, some are both. |
014.41
|
|
|
Comets are made of
|
ice and frozen gas.
Yes. Sometimes called a 'dirty snowball'. |
014.42
|
|
|
The Asteroid Belt lies between the orbits of
|
Mars and Jupiter.
Yes. That is where most of the asteroids are |
014.43
|
|
|
The paths of comets usually
|
extend far beyond the orbit of Pluto.
Yes. Only a few of them get captured into orbits smaller than that. |
014.44
