Reykjavik, Iceland, is at 64 N latitude, whereas Whitehorse, Yukon is at 60 N latitude. However, Whitehose gets much colder in the winter, and much warmer in the summer. Which of the following best explains the difference in temperature ranges between these two cities? Temperature data are more accurate in Reykjavik than in Yukon, Whitehorse is on the coast. Reykjavik is inland. Reykjavik receives cold water from the Canary current. O Whitehorse is much closer to the equator than Reykjavik is. Reykjavik receives water from the Gulf Stream giving ita moderate climate all year long,
The Correct Answer and Explanation is :
The correct answer is: Reykjavik receives water from the Gulf Stream, giving it a moderate climate all year long.
Explanation:
The difference in temperature ranges between Reykjavik and Whitehorse is primarily due to the influence of ocean currents. Reykjavik, the capital of Iceland, experiences a much milder climate compared to Whitehorse, even though it is located farther north. This is because Reykjavik is significantly impacted by the Gulf Stream, a warm ocean current originating in the Gulf of Mexico that flows across the Atlantic Ocean towards the northwest. The Gulf Stream has a warming effect on the surrounding regions, including Iceland, and helps moderate temperatures throughout the year.
In the winter, the Gulf Stream prevents Reykjavik from experiencing extremely cold temperatures that would be expected at its latitude (64°N). The warming influence of the current helps maintain relatively mild temperatures even in the depths of winter. In the summer, the Gulf Stream also helps moderate the climate, preventing temperatures from getting too hot.
On the other hand, Whitehorse, located in the interior of the Yukon at a slightly lower latitude (60°N), is much colder in winter and warmer in summer. Whitehorse does not receive the moderating influence of ocean currents. The climate in Whitehorse is continental, meaning it is influenced by the large landmass of northern Canada, which heats up quickly in the summer and cools down rapidly in the winter. As a result, Whitehorse experiences a much more extreme seasonal temperature variation compared to Reykjavik.
Thus, the moderating effect of the Gulf Stream on Reykjavik’s climate is the key factor that explains why Reykjavik has more moderate temperatures than Whitehorse, despite being farther north.
