What type of atmosphere was the yalta conference held in?
The atmosphere was one of concern regrading European countries. The big three discussed how former Regions occupied by Germany during the war would be reintegrated into society.

Weather, in the sense that we experience on Earth, such as wind and rain ect., does not exist anywhere that there is no atmosphere. An atmosphere can be any type of gas that is held to a celestial body by it's own gravity. So basically to put things very very simply, out in empty space, past the Earth's atmosphere, has no weather.
A conference bridge is an extension of a conference call, which in turn is a type of call that allows more than two people to participate by talking or listening. The conference bridge is a piece of equipment that acts as a kind of direct link to the conference. An individual can dial in through a specific number or P.I.N. and enter the conference directly instead of being added in manually by another caller.
gravity controls the amount of atmosphere that a planet has because the more gravity that a planet has, the more atmosphere it can hold in. God controlled the type of atmosphere a planet had at the start, but since then, the chemical reactions on its surface, volcanic activity, and similar things have changed it slightly.
