...The Earth's atmosphere is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night. Dry air contains roughly (by volume) 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, and trace amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%. Read full entry

Earths atmosphere?
When you leave the Earths
atmosphere and enter space, is
there a definitive line
between the atmosphere and
space, or do you pass through
them gradually. Sorry if this
seems a bit vague but i'm not
sure how to word it.

its gradual. when you get further from the earths center, the air in the atmosphere has less gravity from the earth pulling on it. thats why the air is "thinner" as you go up a mountain. the vaccum of space is just where the gravity is weak enough that the air isnt pulled toward earth fast enough to extend the atmosphere. |

Is it true that nuclear bombs My science professor shortly
discussed how atomic and
nuclear bombs have either a 1
and a million or billion
chance of setting the Earths
atmosphere on fire. This
statistic would then be
greater than winning the
Megabucks Lottery.
Is this statement true that a
nuclear bomb can set Earth's
atmosphere on fire?
As i should have posted this
question when it was fresh on
my mind and I had all my facts
right...
My professor had actually told
us several facts, yet I cannot
seem to remember any as of
right now.

No. So far it has not been proved as true despite dozens of atmospheric tests. There is no scientific basis for postulating that this could happen. |

how can something be before it how big can something be
before it cant enter the
earths atmosphere. and if it
does then what would happen?
whould it blow the atmosphere
away?

Objects of any size can enter the Earth's atmosphere. We don't exactly have a security guard keeping out the big ones. |
