Why are the densities of terrestrial planets greater than Jovian planets?
Yes. The Terrestrial Planets (Mercury, Venus, Earth and Mars) are primarily composed of rock, whereas the Jovian Planets (or Gas Giants) (Jupiter, Saturn, Uranus and Neptune) are composed of gases, and thus their densities are significantly less. For example The Earth has a mean density of approximately 5.5g cm3 whereas Saturn has a mean density of 0.687g cm3 which is less than water. If you could find a bath large enough and enough water, Saturn would actually float.
Which planet has the heaviest atmosphere?
all planets have atmospheres. However, Mercury has extremely low atmospheric pressure, Mars has an atmosphere way below the Armstrong Limit, and Venus and the Outer worlds have way too high of an atmosphere.
How do you describe mercury's atmosphere?
Mercury barely has an atmosphere at all. So little that it might as well have no atmosphere.
Why is there so little atmosphere on the moon?
Because it does not have enough gravity to "hold" onto an atmosphere.
How did the jovian planets form?
it was first a cloud fragment of ice and cold air, in turned into a large spinning disk, then the fusion and heat got so hot the nebula and made the sun, the the rest that didn't formed into a bunch of balls, that are now eight planets.

How does Earth compare in size to the other planets?
Earth is a little bigger than the other terrestrial planets (Mercury, Venus, and Mars), but the immensity of the jovian planets (Jupiter, Saturn, Uranus, and Neptune) cannot be matched by Earth's. Jupiter, the largest planet, has a diameter over eleven times greater than that of Earth.
Why do you suppose storms on the Jovian planets last for years to centuries while on Earth they last for only a few days?
I suppose (this being my opinion and not certain fact) that is because the Jovian planets are more uniform on their "surface." Note how storms on Earth gain power over warm water, but lose power over land or cold water. Planets like Jupiter, are much more fluid (if not entirely fluid) and so their is little temp difference between it's equator and it's poles, so the stroms feel the same in either place. Jupiter also does not have land (or if it does, it is so far down into it that it makes little to no difference) for the storm to lose power over. Basically, our Earth has places for storms to grow, and to die. Jupiter (and the other Jovian planets) only have places for storms to grow and no where to die.
Name the two models of thesolar system and expain the difference between them?
There are the gas giant planets (Jovian planets) and the rocky planets (Terrestrial planets).Terrestrial planets comprise Mercury, Venus, Earth and Mars.They are mainly composed with solid rocks.They have little or no atmosphere.They are found close to the Sun in the warmer region of the Solar System.They are relatively small in size.They have few or no moons.They do not have ring systems (like Saturn).Jovian planets comprise Jupiter, Saturn, Uranus and Neptune.They are composed of thick gaseous atmospheres with liquid interiors. Nothing can land on them.They have thick atmospheres.They are found far from the Sun in the colder region of the Solar System.They are very large in size.They have many moons.They do possess ring systems.Minor comment: It's nice to see "comprise" used properly.
Does earth have a little atmosphere?
It has more than a little atmosphere.
Why do planets like mercury have many more crater holes then earth?
Earth has an atmosphere unlike Mercury. Since Earth has an atmosphere, the meteriors burn up before they hit the ground. Mercury has little to no atmosphere so the meteriors are free to hit the ground and make craters.
Why does the Earth have an atmosphere?
Yes, the earth does have an atmosphere. Part of it is the air you breathe.
Can you see other planets better on the moon?
The moon offers a better view of the stars because it has very little atmosphere compared to the earth, so there is less to get in the way.
What other planets have greenhouse gases?
Two other planets besides Earth.Venus has a runaway greenhouse effect, with most of its atmosphere carbon dioxide, and a temperature of 460° Celsius.Mars has a very faint greenhouse effect, with a little carbon dioxide, but hardly any atmosphere at all.Saturn's largest moon, Titan, has a greenhouse effect, with large concentrations of methane.
When was Kokoro no Wakusei - Little Planets - created?
Kokoro no Wakusei - Little Planets - was created on 2005-05-25.
Which planet has the heaviest atmosphere?
all planets have atmospheres. However, Mercury has extremely low atmospheric pressure, Mars has an atmosphere way below the Armstrong Limit, and Venus and the Outer worlds have way too high of an atmosphere.
Why are asteroids called mirror planets?
They are sometimes called minor planets (not mirror planets).They aren't planets really, but they are a bit like little planets orbiting the Sun.
