Which question would be the best high level scientific question?

a. how long ago did dinosaurs live on earth?

b. does the amount of salt in water affect the temperature at which it boils?

c. who made the first microscope?

d. how many giraffes live in africa?

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
