What causes the weather?

Question

I had this question on an assessment recently:

What causes the weather?

(a) Sunlight

(b) Wind

(c) Oxygen

(d) Clouds

I guessed clouds because I had no idea what it was. Does anyone know what the answer is and why?

Thanks in advance!

Answer 1

Sunlight;because the unequal heating of the different places on the earth is the main cause for all weather conditions.

Answer 2

D.      but is a dumb question ... really...

Answer 3

sunlight

>>The sun causes all our weather because it heats the earth unevenly. The contrast between the hot parts and the cold parts of the earth turns our atmosphere into a powerful engine.  The engine keeps cold and warm air moving and makes changes in air pressure.  Those air pressure changes cause wind.  The heat of the sun also helps moisture to rise and form clouds, bringing rain, snow, or thunderstorms.  So all the changes in our weather come, at least indirectly from the sun.
