Question
Figure 13.9 presents the annual temperature curves for two cities, A and B, that are located in North America at approximately 37°N latitude. On any date, both cities receive the same intensity and duration of solar radiation. One city is in the center of the continent, whereas the other is on the west coast. Refer to Figure 13.9 to complete the following.

___ Explanation:
City B
City A
Mid-continent locations often experience a greater annual temperature range and reach their maximum temperatures earlier than coastal locations because of the effect of water along the coast.
Coastal locations often experience a greater annual temperature range and reach their maximum temperatures earlier than mid-continent locations because of the effect of water along the coast.
A.City B
B.City A
C.Mid-continent locations often experience a greater annual temperature range and reach their maximum temperatures earlier than coastal locations because of the effect of water along the coast.
D.Coastal locations often experience a greater annual temperature range and reach their maximum temperatures earlier than mid-continent locations because of the effect of water along the coast.
Explanation / Answer
Here both cities are on the same latitude (37°N), having the same intensity and duration of solar radiation.
Now the primary thing we have to understand is that the city which is near the coast has little change in its temperature during day and night times. Because during day time the temperature of the land area increases very fast than the oceanic part. The hot light air will rise up, and in the same time the heavy relatively cold air from the oceanic part will come and fill the void area of the continental part. In the night same thing happened by the vice-versa process. In this way, there (the city near the ocean coast) will not any significant temperature rise throughout the season due to oceanic influence. But the city in the middle of the continent will not have this benefit. So, there will be huge temperature rise and fall.
So, as per your question,
5) The city in the middle of the continent has the highest monthly mean temperature.
6) The city on the west coast has the lowest monthly mean temperature.
7) The city in the middle of the continent has the greatest annual temperature range ( the difference between highest and lowest monthly mean temperatures).
8) The city on the west coast its maximum monthly mean temperature at an earlier date. (As there are not very rough temperature changes, so mean temperature will reach soon).
9) The city on the west coast maintains more uniform temperatures throughout the year.
10) Explain at the start.
