ok.....let me throw the answer to the last one:
d) 6 a.m.
Suprisingly, the part of the day with the highest relative humidity is also the coolest. During the course of a summer day, the actual amount of moisture in the air typically changes very little--while the temperature rises 20 or more degrees from the daybreak reading. As it does so, the relative humidity decreases, and reaches a minimum at the the hottest part of the day. After sunset, as the temperature falls, the relative humidity increases again, reaching a maximum as the temperature bottoms out around dawn.
d) 6 a.m.

Question 4
Sir Edmund Halley, the distinguished discoverer of the popular Halley's Comet, was a man of extraordinary scientific talent. With a little help from his friend, Sir Isaac Newton, Halley determined that the orbit of this comet was elliptical and that it would reappear every 76 years. Now most folks do not realize that besides his keen interest in astronomy, Sir Edmund was also a dabbler in early 18th Century weather. What meteorological breakthrough is credited to Sir Edmund Halley? Was Halley the first to:
a) track a hurricane
b) map the trade winds
c) describe warm and cold fronts
d) discover the Gulf Stream near England

This one was hard but I would think that the gulf stream was all ready found in the 17th century and hurricanes may of been but I heard some thing about him mapping the trade winds in the 18th hundreds. It can't be cold fronts in warm fronts because of that was made in the early 20th century. So the trade winds would have to be it because a hurricane was not tracked intill the earler 19th century.

close....
d) discover the Gulf Stream near England
Sir Edmund Halley noted that the unusual mildness of southwestern England was due in large part to the warmth of the ocean. He deduced that the water in the Atlantic circulated like the winds and brought warm sea water from the Tropics to the tip of the United Kingdom.

Welp...one more before I call it a night! lol Here goes:
Question 5
A clever meteorologist once said "The solution to pollution is dilution. The truth behind this witticism is that pollution from smokestacks and the like becomes a great problem only when the great mixing and therefore, diluting powers of the atmosphere are restricted by certain weather conditions. Which of the following situations is associated with severe pollution episodes?
a) temperatures increasing with height
b) temperatures decreasing with height
c) relative humidity increasing with height
d) relative humidity decreasing with height

a) temperatures increasing with height
was the right answer!
As most pollutants are emitted at ground level, in order to insure proper dispersal, mixing must take place through a sufficiently deep layer within the lower atmosphere. For deep mixing and the dilution solution to pollution, vertical air currents must occur. When the temperature falls rapidly with increasing height, vertical air currents readily occur. However, when the temperature either falls slowly or even increases with height, vertical currents are inhibited and pollutants are effectively trapped near the ground-close to their sources.
