The point where R.Isbo meets R.Gembeh is called

Analyze the question: The question asks for the name given to the point where one river (R. Isbo) meets another river (R. Gembeh).

Explain the concept: Let's look at each option:

• Entrepot: A trading centre or port where goods are imported and then re-exported (e.g., Singapore, Hong Kong). It has nothing to do with rivers joining.
• Watershed: The high land or ridge that separates one drainage basin from another. It is a dividing line, not a meeting point.
• Lagoon: A shallow body of water separated from the open sea by a sandbar or reef (e.g., Lagos Lagoon).
• Confluence: The point where two or more rivers or streams meet and join into one. The smaller river is called the tributary, and the bigger one it joins is the main river.

Solution:

1. Two rivers (Isbo and Gembeh) are coming together.
2. The geographical term for the place where rivers join is a confluence.
3. Other options relate to trade (entrepot), drainage divides (watershed), or coastal water bodies (lagoon).

A good Nigerian example is Lokoja, where the River Niger and River Benue meet. That point is a confluence.

Answer: The correct option is D. A confluence.

Tip: Think of the word parts: con- means "together" and fluence comes from "flow." So confluence = flowing together. Also remember that a watershed does the opposite, because it separates drainage basins.
