3.Explain three differences that are observed between the Terrestrial and Jovian planets.?

Question

There are many differences between the Terrestrial and Jovian planets. The three reasons, I observed, are temperature, surface matter, and orbital speed. The Terrestrial planets have a hotter surface than the Jovian planets. This is because the Terrestrial planets are closer to the Sun. The surfaces are also different because the surfaces of the Terrestrial planets are solid while the Jovian planets surfaces are liquid. Also, the Terrestrial planets have a faster orbital speed than the Jovian planets because they are closer to the Sun.


Am I right?

Answer 1

There are also more differences between the types of planets. Your answers are correct, however more conventionally, the differences are:
-density (terrestrial planets are MUCH denser than jovians)
-mass (jovians are MUCH more massive than terrestrial)
-radii (Jovians have MUCH larger radii)
-surfaces (Terrestrials have solid surfaces, Jovians don't)
-magnetic fields (Jovians have STRONG ones, terrestrials are weak)
-Moons (Terrestrials have few or no moons, Jovians have a plethora)
-Rings (Terrestrials have no rings, all jovians have rings)

Answer 2

Terrestrial planets have solid surfaces, Jovians have not, they are all gaseous. You wouldn't be able to land on Jupiter for example, as there is no solid surface in it!

Then, terrestrial planets are much denser than Jovians. If you had a water ocean big enough to drop Saturn in it and see what happened, Saturn would flow!

Finally, terrestrial planets are much smaller than Jovians. This is because when terrestrials were forming they accreted much less mass than Jovians due to their shorter distance from the Sun.

Answer 3

Some of the differences noted in other answers have nothing to do with the planets themselves (for example, orbital speed, surface temperature; they are the result of orbital mechanics (if the earth were placed in the orbit of Neptune it would have the same orbital velocity, for instance)

The main differences that are actually due to the properties of the planets are: very thick atmospheres with only a small, rocky core(1), large diameter (2), and low density (3). Others might be the possession of a ring system (there is no reason, however, that a terrestrial planet could not have a ring), possession of satellites consisting mainly of water ice, and having the property of emitting more heat than they get from the sun (I don't know if the outermost two, (Uranus and Neptune) have this property).

Answer 4

You are right except that the Jovian planets surfaces are not liquid but mostly composed of gases. A forth difference is that the Jovian planets are much bigger than the Terrestrial planets because they are cold enough to have held on to tremendous amounts of gases whereas the Terrestrial planets have thin or no gaseous atmospheres.
