Final answer:
The cartographic feature that runs through North America is the Continental Divide, which separates rivers flowing eastward from those flowing westward.
Step-by-step explanation:
The cartographic feature that runs through North America is the Continental Divide. This is a line of the highest points in North America that separates rivers flowing eastward from those flowing westward. It stretches from Mexico to Canada and marks the boundary between the Pacific and Atlantic watersheds.
For example, in the United States, the Continental Divide follows the Rocky Mountains, which is a major mountain range that runs through the western part of the country. On one side of the divide, rivers flow toward the Pacific Ocean, while on the other side, rivers flow toward the Atlantic Ocean.
In summary, the cartographic feature that runs through North America is the Continental Divide, which separates rivers flowing eastward from those flowing westward and stretches from Mexico to Canada.
