Which one is the correct question? Please also being timed thanks! Why is the Continental Divide important?

It forms two river systems.
It combines two large ice sheets.
It separates two major watersheds.
It splits two large rivers through tributaries.

The Continental Divide is important because it separates two major watersheds.

Explanation:

The Continental Divide is a chain of mountain ranges that runs through North America, from Alaska to Panama. This chain of mountain ranges is dividing the continent into two major watersheds. It runs through eastern Alaska, western Canada, western United States, and through the central parts of Mexico and Central America.

The waters from the eastern side of this watershed divide mostly end up in the Atlantic Ocean and its seas, and partially in the Arctic Ocean and its sea. The waters from the western side of this watershed divide end up in the Pacific Ocean and its seas. The eastern watershed has significantly more water running through it than the western one, with the main reason being that the eastern one is significantly larger.

The Continental Divide is important as it separates two major watersheds.

Explanation:

The natural boundary or ridge that separates the river systems of a continent is said to be the continental divide. Each river system has a different end points as they feed into different sea, bay or ocean basin.

Continental divides are continent-wide and broad, some examples are drainage divides, and sometimes they are just called divides. Divides are boundaries separating the watersheds or drainage basins of distinct sizes. Without paying any attention to the scale, Drainage divides occurs in elevated terrain like the hills or mountain ranges.
