Which statement is true regarding the relationship between offshore currents and temperature?

The statement about offshore currents affecting surface temperatures is accurate because it highlights how these currents play a significant role in regulating the thermal characteristics of coastal regions. Offshore currents are large-scale, continuous movements of water in the ocean, often influenced by wind patterns, the Earth's rotation, and differences in water density. They help to distribute heat from the equator toward the poles, leading to variations in temperature along coastlines.

For example, warm currents—like the Gulf Stream—transport warmer water from tropical regions to higher latitudes, which can raise the temperatures of nearby coastal areas. Conversely, cold currents can bring cooler water from polar regions, reducing the temperature of the coastal region they pass. Therefore, understanding how these currents operate is crucial when studying climate variations and localized weather patterns.

In this case, recognizing that offshore currents impact surface temperatures allows for a deeper comprehension of climate differences that exist between various geographical areas, such as those found in Maine compared to Spain. The other statements do not accurately reflect the relationship between currents and temperature in this context.
