Answer the questions 11 to 15 after reading through
the following passage. Base your answers on
information that is either stated or implied in the passage.

A weather map is an important tool for geographers. A succession of three or four maps presents a
continuous picture of weather changes. Weather foreca
sters are able to determine the speed of air
masses and fronts; to determine whether an individual pressure area is deepening, or becoming
shallow and whether a front is increasing or decreasing in intensity. They are also able to determine
whether an air
mass is retaining its original characteristics or taking on those of the surface over
which it is moving. Thus a most significant function of the map is to reveal a synoptic picture of
conditions in the atmosphere at a given time.

All students of geography

should be able to interpret a weather map accurately. Weather maps
contain enormous amount of information about weather conditions existing at the time of observation
over a large geographical area. They reveal in a few minutes what otherwise would take h
ours to
describe. The United States weather bureau issues information about approaching storms, Hoods,
frost, droughts and all climatic conditions in general. Twice a month it issues a 30 day “outlook”
which is at rough guide to weather conditions likely t
o occur over broad areas of United States. These
30 day outlooks are based upon an analysis of the upper air levels which often set the stage for the
development of air masses, fronts and storms.

Considerable effort is being exerted lo achieve more accurat
e weather predictions. With the use of
electronic instruments and earth satellites, enormous gains have taken place recently in identifying
and tracking storms over regions which are but few meteorological stations. Extensive experiments
are also in progre
ss for weather modifications studies but the limitation of weather modifications have
prevented meteorological results except in the seeding of super cooled, up slope mountains winds
which have produced additional orographic precipitation on the Windward s
ide of mountain ranges.
Nevertheless, they have provided a clearer understanding of the fundamentals of weather elements.

(A)Barometric Pressure (B) Fronts (C) Thermal Cha
nges (D) Frost (E) Wind Speed

12. The 30 day forecast is determined by examining

eous because it

14. A weather map is synoptic because it

(A) Summarizes a

great deal of information (B) Appears Daily (C) Shows changing fronts (D) Can be

15. At the present time, experiments are being conducted in

(A)Manipulating weather (B)Determining density of pressur

"Outlooks" (E) Controlling storms

Answer the questions 16 to 20 after reading through the following passage. Base your answers on
information that is either stated or implied in the passage.

Agreeable to your request, I
send you my reasons for thinking that our northeast storms in North
America begin first, in the point of time, in the southwest parts: That is to say, the air in Georgia, the
farthest of our colonies to the southwest, begins to move southwesterly before th
e air of Carolina,
which is the next colony northcastward; the air of Carolina has the same motion before the air of
Virginia, which lies still more northeaslwardg and so on northeasterly through Pennsylvania. New
York, New England, &c., quite to Newfoundl

These northeast storms are generally very violent, continue sometimes for two or three days, and
often do considerable damage in the harbors along the coast. They are attended with thick clouds
and rain.

What first gave me this idea, was the following

circumstance. About 20 years ago. a few more or
less, I cannot from my memory be certain, we were to have an eclipse of the moon at Philadelphia,
on a Friday evening, about 9 clock. I intended to observe it, but was prevented by a northeast storm,
which c
ame on about seven, with thick clouds as usual, that quite obscured the whole hemisphere.
Yet when the post brought us the Boston newspaper, giving an account of the effects of the same
storm in those parts, I found the beginning of the eclipse had been we
ll observed there through
Boston lies N.E. of Philadelphia about 400 miles. This puzzled me because the storm began with us so
soon as to prevent any observation and being a N.E. storm, I imagined it must have begun rather
sooner in places farther to the n
ortheastward than it did in Philadelphia. l therefore mentioned it in a
letter to my brother who lived in Boston; and he informed me the storm did not begin with them till
near 11o’clock, so that they had a good observation of the eclipse: and upon compari
ng all the other
accounts I received from the several colonies, of the time of the beginning of the same storm, and,
since that of other storms of the same kind, I found the beginning to be always later the farther
northeastward. I have not my notes with m
e here in England, and cannot, from memory, say the
proportion of time to distance, but I think it is about an hour to every hundred miles.

From thence l formed an idea of the cause of these storms, which l would explain by a familiar
instance or two. Supp
ose a long canal of water stopped at the end by a gate. The water is quite at
rest till the gate is open, then it begins to move out through the gate; the water next to that first
water moves next, and so on successively, till the water at the head of the
canal is in motion, which
is last of all. In this case all the water moves indeed towards the gate, but the successive times of
beginning motion are the contrary way, viz. from the gate backwards to the head of the canal. Again
suppose the air in a chamber

at rest, no current in the room till you make a fire in the chimney.
Immediately the air in the chimney, being rarefied by the fire, rises; the air next the chimney flows in
to supply its place, moving towards the chimney; and, in consequence, the rest of

the air
successively, quite back to the door. Thus to produce our northeast storms. I suppose some great
heat and rarefaction of the air in or about the Gulf of Mexico; the air thence rising has its place
supplied by the next more northern, cooler, and th
erefore denser and heavier, air; that being in
motion is followed by the next more northern air, &c. &c., in a successive current, to which current or
coast and inland ridge of mountains give the direction of northeast, as they lie N.E. and S.W.
