Why are the laid out the way they are?

[Mrs. Wright]

Why do you think the Terrestrial planets formed closer to the sun and the Jovian planets formed farther away from the sun? Answer here and come back to respond to at least 2 classmates. Remember your netiquette and discussion board rules!

I think the Sun gravity condense the planets closer. The heat from the sun could also add to the fact that it adds energy to the planets surface, which might be too much for a gas or ice made planet.

[madis...@gmail.com]

I think they formed this way because of the fact that terrestrial planets have the chance of providing another planets for life to live on and therefor they need certain amounts of sunlight. Jovian planets simply may not require as much sunlight because of the overall fact they they're planets that have no chance of supporting life.

The planets that are close to the sun formed out to be Terrestrial planets because of the suns gravity condensing the gas particles that they once were and since the Jovian planets aren't as close to the sun as the Terrestrial ones are they aren't under the affect of the suns gravity as much.

[Maximus Lorah]

I agree that the suns gravity had some play in the way they formed.

[lyti...@gmail.com]

I agree with most of the respondents about how the Sun's gravity in some way condensed the gas particles. I also believe it had sometime to do with the Sun's temperature.

[jorgen...@gmail.com]

I personally think that the suns gravity has a big part to do with them. Maybe the rocky planets can withstand greater gravity than the gas planets can?

[amjon...@gmail.com]

I think the Terrestrial planets formed closer to the Sun than the Jovian planets because the Sun's heat and gravity had a stronger affect of them. The heat prevented ice and certain gases from staying and the gravity compressed them resulting in their small size.

[bowi...@gmail.com]

I feel like it might have something to do with atmospheres. If I'm recalling correctly, all the Jovian planets have thick atmospheres, and I feel like that means that there was more pressure put into them when they were forming.

[jorgen...@gmail.com]

i think that you may be right because being closer to the sun would compress the planet more than not being close to it.

[bowi...@gmail.com]

You bring up a good point. The sun is probably the prime factor for this debate.

[jorgen...@gmail.com]

I personally disagree because I think that the gravity from the sun is what made the planets the way they are.

[bowi...@gmail.com]

That makes a lot of sense actually. I think you did a very good job of explaining it.

[billu...@gmail.com]

I think the Terrestrial planets needed a heat source to have the chance of sustaining life. Where as the Jovian planets do not have the qualities to sustain life so, they did not need much of a heat source.

[njimen...@gmail.com]

I believe that the heat from the sun didn't allow the closer planets to hold gasses while the farther ones were cooler so they could hold them.

[madis...@gmail.com]

i agree,that's a very good point

[astu...@gmail.com]

I think it must have something to do with the heat of the sun, considering that the inner planets are much hotter than the cold, icy outer planets. Perhaps since the sun is so far from the outer planets, they were able to take in all that ice as it collided into them or were pulled into its spinning gravity.

[edbs...@gmail.com]

I think they were formed closer to support any kind of life because they would need a sort of warmth to keep them alive instead of freezing, and Jovian planets are further away because there to far to support anything at all.

[astu...@gmail.com]

I also think that the heat and gravity played a big part. I'm not so sure how compression works though, because don't the outer planets have a stronger gravitational pull in their atmosphere?

[edbs...@gmail.com]

I agree the suns gravitational pull plays a huge roll for planets like rock planets.

[astu...@gmail.com]

I believe those thick atmospheres are because of the amount of gases and ice that the planets contain. It must be why they are so dense.

[edbs...@gmail.com]

That's a great point! gas planets cant really support much even though how far away they are.

[cmschwa...@gmail.com]

The planets closest to the sun couldn't retain the gas that the large Jovian planets could so the Jovian planets collected the gas over time and the terrestrial planets remained the rocky bodies they are.

[deval...@gmail.com]

I believe they formed like this, because of the rocky terrestrial are smaller and pulled in closer by the sun's gravity where as the gas planets are giant and have stronger gravitational pull from farther distances.

[deval...@gmail.com]

I agree that since the terrestrial planets have atmospheres they were able to remain the rocky bodies they are, while gas planets collected it over time

[vtna...@gmail.com]

i think its because the because the terrestrial planets are closer to the sun and the Gas planets where made to have more gas than our terrestrial planets

[vtna...@gmail.com]

i agree this is what i said

[vtna...@gmail.com]

i also said that the heat had to do with the closer planets not having much gas.

[perr...@gmail.com]

i believe it is that way because the Jovian planets were cooler when forming so helium stayed there instead of escaping like the terrestrial planets did.

[zac...@hotmail.com]

The planets closest to the Sun had lighter gases which were taken away by the Sun's energy, leaving mostly rocky formations. Jovian planets were farther away and their gases were not taken by the Sun.

[zac...@hotmail.com]

I agree, I think it has to do with the Sun's heat, as well.

[zac...@hotmail.com]

I agree, I said something very similar.

[chloea...@gmail.com]

The smaller the planet the closer to the sun because the suns temperature and gravitational pull effects the way planets are formed

[shanecu...@gmail.com]

The Jovian planets have relatively small, dense cores surrounded by massive layers of gas, Made almost entirely of hydrogen and helium, these planets do not have solid surfaces. The main structures of the Jovian planets are opposite those of the terrestrial planets. Rather than having thin atmospheres around relatively large rocky bodies.

[shanecu...@gmail.com]

i agree, the sun does have a big role especially the suns gravity had to do with the way they formed.

[shanecu...@gmail.com]

i agree, the sun doesn't allow the closer planets to hold gases.

[hanw...@gmail.com]

Terrestrial planets are closer to the sun which allows the possibility of life where as Jovian planets are just huge planets.

[jasminca...@gmail.com]

Thanks for agreeing!

[jasminca...@gmail.com]

Good thinking on the compression, but it think that the fact the terrestrial planets have a lighter atmosphere then jovian planets is no coincidence.

[deval...@gmail.com]

I agree that gas planets can not really support much because they are made mostly out of gas.

[caria...@gmail.com]

I agree that the sun had a lot to do with the formation of the planets. It made the pressure of gravity and the heat to form the rocky planets. It also allowed the Jovian to keep the elements to form their interiors.

[bail...@gmail.com]

I think the gravity from the sun makes the closer planets become smaller and more compact while the outer planets are able to expand.

[bail...@gmail.com]

I agree that it has to do with gases

[bail...@gmail.com]

This is a good point!
