Which factor primarily contributes to the seasonal temperature variations in areas surrounding Lake Ontario?

• A. Urban development
• B. Lake temperature stabilization
• C. Industrial activity
• D. Geographic elevation

Answer: (B)

The primary contributor to seasonal temperature variations in areas surrounding Lake Ontario is the stabilization of lake temperatures. This phenomenon occurs because large bodies of water like lakes have a high specific heat capacity, meaning they can absorb and store heat efficiently. During the warmer months, Lake Ontario absorbs heat from the sun, warming the water and creating a microclimate in its vicinity. This stored heat is then slowly released into the surrounding air, moderating temperature fluctuations and leading to milder conditions in the summer and warmer temperatures in the cooler months. In contrast, other factors such as urban development, industrial activity, and geographic elevation can influence local weather patterns and temperatures, but they do not have the same stabilizing effect as the lake itself. Urban areas may experience heat islands, while industrial activities can contribute to localized temperature changes, and geographic elevation can affect climate through altitude differences, but none of these factors have the consistent and broad impact on seasonal temperature stabilization seen with the lake's influence. Thus, the lake’s effect is crucial in understanding the climatic nuances of the region surrounding Lake Ontario.
