Final answer:
The continent that includes the coordinates of 45°N latitude includes parts of both Europe and Western North America, with areas like the Great Lakes and St. Lawrence River/Seaway in North America and certain regions of Europe matching these coordinates.
Step-by-step explanation:
The continent that includes the coordinates of 45°N latitude encompasses parts of both Europe and North America. When examining the geographic information provided, it's evident that Europe's latitude extends from about 70°N to 40°N, with a median near 50°N, which means 45°N would fall within this range.
Similarly, certain regions of Western North America, such as those from the British Isles to Oregon and California, ranging from 37°N to 45°N, would also include the 45°N latitude. Moreover, the Great Lakes and St. Lawrence River/Seaway have a latitude median right at 45°N.
Therefore, the location in question could be in parts of Western Europe or Western North America.
