2) Scientists hypothesize that the sun formed ________years ago.
(write in numerical form) (thats numbers)

3)__________ has the hottest average temperature of all the planets

okkk look i dont have a textbook and its not cheating!!!! Our teach. said we can go on the comp and do them

papa john u got it...

u tricked me

god is right but not he answer i need


ill put as best when it lets me

actually its not

ill wait

actually its not

ill wait

Answer 1

1) a huge cloud of gas
2) about 5 billion years ago
3) Venus (due to the greenhouse effect)

Answer 2

3)Venus:
According to NASA, the mean temp of Mercury is only 333F while the average temp of Venus is 867F.

2) With the latest computer models based on how we know stars form, they have come up with a figure of at least 4.57 billion years.

1)From studies of other stars which astronomers can see in many different stages of their 'life cycle', it seems pretty convincing from the data that the sun must have started out as a large collapsing cloud of gas inside some ancient interstellar cloud. This cloud was 'polluted' by a supernova several million years before the collapse phase ended, because we see certain isotopes of aluminum which could not have been a part of this cloud for very long unless they had been implanted by such an event.

The cloud collapsed for millions of years until it formed a rotating disk with a large central bulge. Out of the disk would eventually form the planets, and out of this central bulge where most of the mass wound up, formed the sun. We see such rotating disks of gas around many infant stars embedded in nebulae so this has confirmed this basic picture during the last 15 years or so. This isn't just 'theory' anymore.

The central bulge continued to collapse under its own gravity until deep in its interior the temperatures got so high...several million degrees....that deuterium atoms began to fuse and give off thermonuclear energy. This slowed the collapse down a bit and eventually led to a second stage where hydrogen nuclei could fuse into helium, which then started the sun's current evolutionary phase.

While all this was happening, the surface of the sun became very active and produced a powerful wind which blew out all of the remaining gas and dust in the surrounding disk of gas which had not settled into the bodies of the new planets that had formed. This 'T-Tauri wind' also scoured clean the atmospheres of the inner planets so that they were bare rock. Those that were volcanically active, however, were able to regenerate their atmospheres from the gases ejected by volcanic activity.

From start to finish, it took something like 10 million years to form the sun and planets from a collapsing cloud of gas, and this is not very long at all!!

Answer 3

1) hydrogen, (or spacious gases drifting around and collecting in on itself due to gravity.)
2) 13 billion years ago (approx. I think it was a Tuesday). There are a lot of people that think that it was only about 5 billion years ago but that actually is the age of our planet, where as the sun ignited into a star a lot sooner than that. If I'm wrong about this, sorry.
3) Jupiter, I think,...

Answer 4

1) supernova explosion
2) 5 billion
3)venus

Mercury alternately bakes and freezes, depending on what side is lit by the Sun. The sunlit side can reach up to 950° F (510° C) and the dark side can drop as low as –346° F (–210° C)
The thick clouds that cover Venus create a greenhouse effect that keeps it sizzling at 864°F.

Answer 8

Sounds like we need a text book to answer these..... Wait, I bet you have one right there in front of you.
Do your own homework loser.

Answer 9
