Question

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.

Explanation:

A continental divide is a geographic feature that acts as a boundary; precipitation on one side flows to one ocean/seawater body, while precipitation on the other side flows to a different one. This means it separates two major watersheds (areas where water drains to a common outlet). The other options are incorrect: it does not form river systems directly, does not combine ice sheets, and does not split rivers via tributaries.

Answer:

It separates two major watersheds.
