What is a key feature of the shoreline of Lake Ontario?

The correct choice highlights that the shoreline of Lake Ontario is characterized by numerous bays and harbors. This feature is significant as it contributes to the overall geography and ecology of the area, allowing for a diverse range of habitats and recreational opportunities. The presence of these bays and harbors facilitates maritime activities, including shipping, fishing, and tourism, which are integral to the economic and social fabric of the lakeside communities.

Unlike a uniform shoreline that lacks variation, the bays and harbors provide sheltered areas that can be crucial for both wildlife and boating activities. Additionally, they offer beautiful landscapes that are appealing for residents and visitors alike. This variability along the shoreline is also essential for sustaining various ecological processes and species that thrive in those distinct environments.
