Here's a breakdown of the terms:

* Divide: A divide is a line of high ground that separates different drainage basins. It acts as a barrier, directing water flowing down one side to a particular river or stream, and water flowing down the other side to a different river or stream.

* Watershed: A watershed is a larger area of land that drains to a common point, like a river, lake, or ocean. The divide defines the boundaries of a watershed.

Think of it like this: imagine a hill with two valleys on either side. The top of the hill, the ridge, is the divide. Rain falling on one side of the ridge will flow down into one valley, while rain falling on the other side will flow into the other valley. These valleys are part of different watersheds because they drain to different destinations.

Other terms for divides:

* Continental Divide: This is the most prominent divide, separating the flow of water towards the Atlantic Ocean from the flow towards the Pacific Ocean.

* Drainage Divide: This term emphasizes the role of the divide in directing drainage patterns.
