• C. 1 & 3
• D. All are correct

Answer 1

Answer:

A. 1 & 2

• Correct Answer: Option A (1 & 2)

• "Drainage describes the river system of an area." - This statement is correct. Drainage refers to the pattern and arrangement of rivers and streams in a particular region. It describes how water flows across the landscape through interconnected river systems.

• "A drainage basin is an area drained by a single river system." - This statement is also correct. A drainage basin (also called a watershed or catchment area) is the total area of land from which a single river and its tributaries collect water. All precipitation that falls within this area eventually flows into that particular river system.

• "The term 'water divide' refers to the mouth of a river." - This statement is incorrect. A water divide (or watershed divide) actually refers to the elevated boundary line that separates neighboring drainage basins. It's the ridge or high ground that determines which direction water will flow. The mouth of a river, by contrast, is where the river empties into another body of water like an ocean, lake, or larger river.
