Question

Which statement is false about the atmosphere?

(1) People depend on the atmosphere for the air they breathe.
(2) It screens out the sun's ultraviolet rays.
(3) As air rises, it gets warmer.
(4) Warm air has more moisture content than cool air.

Answer 1

You can use process of elimination here. The atmosphere is a key component for the air we breathe. The atmosphere protects us from harmful objects and rays. Finally, warm air has more moisture in it than cool air (for example why generally hot places are so humid).
