Question

the climates of cities along the west coast of the united... part a: which city most likely has the warmest climate?
a. city a
b. city b
c. city c
part b: what is the main reason this city has the warmest climate?
a. it is closest to the warmest ocean current
b. it is at a higher elevation and closer to the sun
c. it has more tropical plants that release heat from the sun
d. it is closer to the equator and receives more direct sunlight

Explanation:

Part A

To determine which city has the warmest climate, we analyze the ocean currents and latitude. The Alaska Current is warm, and City A is near it and at a higher latitude (closer to the warm current's influence), but wait, actually, City C is at a lower latitude (closer to the equator - like 37°N vs 40°N and 46°N). Wait, no, the California Current is cold, Alaska Current is warm. City A is near Alaska Current (warm), City B is between, City C is near California Current (cold). But latitude: lower latitude (closer to equator) means more direct sunlight. Wait, maybe I misread. Wait, the map: City A is at ~46°N, City B at ~40°N, City C at ~37°N. Lower latitude (City C) is closer to equator, so more direct sun, warmer? But wait, ocean currents: Alaska Current (warm) flows along the north, California Current (cold) along the south. Wait, maybe the question is about which is warmest. Wait, maybe the options: if City C is at lower latitude (37°N) vs A (46°N) and B (40°N), lower latitude means warmer climate (more solar radiation). So City C (Option C) would be warmest? Wait, no, maybe the Alaska Current warms City A. Wait, maybe the problem is about the west coast of the US. Alaska Current is warm, California Current is cold. So City A (near Alaska Current) and City C (near California Current). But latitude: City C is at 37°N (like Los Angeles), City A at 46°N (like Seattle), City B at 40°N (like San Francisco). Los Angeles (City C) has a warmer climate than Seattle (City A) because of lower latitude, even though California Current is cold, the lower latitude gives more sun. So Part A answer: C. City C.

To find the main reason for the warmest climate, we evaluate options:

• Option A: Closest to warmest ocean current? Alaska Current is warm, but City C is near California Current (cold). So A is wrong.
• Option B: Higher elevation and closer to sun? Higher elevation would be cooler, and "closer to sun" is negligible. Wrong.
• Option C: More tropical plants? That's a result, not a cause. Wrong.
• Option D: Closer to equator (lower latitude) means more direct sunlight (solar radiation), leading to warmer climate. Correct.

Answer:

C. City C
