What do u think would be the perfect environment for earth? perfect weather?

beautiful sunny days not too hot and breezy and clean fresh air.  also would depend on the people, species, and other things in the environment.  should be less pollution too.  So there's lots to have a beautiful and wonderful environment and weather in nature.

Afraid not.  The only planet in our solar system that has the temperature and atmosphere that will sustain life is good old Earth.

The Planet in which we all live on.

Soil and climate conditions.

Nuclear bombs, pollution, war, famine, disease, weapons, lack of food, lack of water, natural disasters, aliens, meteorites, black holes, Apocalypse. Geez, earth has many flaws and problems, doesn't it?

jus air and water?\nwhat about delicious tasty food !! `o` \nand trees ,animals around \nand ozone layer at top \nhmmm... and yeah gravitational force of earth to let us stick over here to live. :D\nThese are enough to survive.

There is a chance that there is life not on earth, but think about the perfect conditions for life that earth has: the perfect temperatures, the correct mixture of oxygen and other gases, and of course, water. If there were life not on earth, it would probally be 1-celled organisms, and not what we would expect.

Wow! another brain-tickling question from Neuro-Prof! What imagination! Yeah, that would be pretty interesting to see. I think a planet with such conditions will be a home for people who'd be considered super-heros by us on earth. Silicon would make their skin rough and abrasive. That would be just awesome!\n\nNow, coming to your question, I think the conditions that would favour such an atmosphere should be-\n1- Extremely high pressure. Pyrolysis is one of the methods to break Si-H bonds.\n\n2- Extremely high temperature.\n\n3- Reducing Atmosphere / Abundance of Dihydrogen. As compared to our earth's oxidising atmosphere, a reducing atmosphere would contribute a lot more in breaking the Si-O bonds.\n\nGreat question, I must say.

A tree. I can provide shade on a hot day,a home  and nourishment for many lifeforms,and reach deep into the earth to commune with essence of the planet. Peace.

All of Earth's weather occurs in the 'troposphere,' which is about 7 miles thick.

Good weather conditions.\nRain and warmth in the spring time.\nPlowing of the fields,  planting crops.\nTreatment for growth.\nSummer warmth,  with some rain.\nCrop treatment for insects if needed,  also\nbeing watchful of animals who would feed off\nthe crops.\nA scheldule for havesting when crops are ready.\nMy Father was a Farmer.  \nI love the smell of dirt.

It would be like Mars.  Mars has an atmosphere, enough that it has wind, dust devils and giant sandstorms.  However, there is not enough incoming solar radiation (aka insolation) trapped by the atmosphere to keep it warm.

The only aswer to this is- grow more and more trees. Trees produce oxygen, it helps to increase rainfall, it helps to maintain temperture. so grow more and more trees and save earth.

I'm guessing with Earth, Water, Fire, and Wind (air).

You may be talking about the BIOSPHERE. It was a giant enclosed bubble with no outside influences to study the "PERFECT" environment. Many experiments took place inside from soil to atmospheric.

the ozone layer keeps the earth a stable temperature.
