How does Lake Ontario impact the climate in surrounding areas?

Lake Ontario plays a significant role in moderating the climate of the surrounding areas primarily due to its large surface area and the heat capacity of water. This water body absorbs heat during the warmer months and releases it slowly during cooler months, leading to a more stable temperature range in nearby regions. As a result, areas close to the lake often experience milder winters compared to those further inland, with less severe temperature fluctuations.

By absorbing excessive warmth in the summer and mitigating cold during winters, Lake Ontario's influence creates a microclimate that can enhance the overall livability and agricultural viability in nearby communities. This moderation of temperature is critical for the growth of various crops and can even affect local ecosystems.

In contrast, the other choices do not accurately capture the primary climatic influence of Lake Ontario. While there may be some changes in precipitation patterns due to lakes, the lake's primary role is to stabilize temperatures rather than necessarily increasing precipitation or enhancing storm severity. Similarly, the lake's presence does not inherently reduce humidity; in fact, large bodies of water often contribute to increased humidity in the surrounding areas.
