Question

What is the name of the rain water that flows into rivers, lakes and ponds?

• A. oceanic
• B. ground water
• C. dorsal burn
• D. fresh water

Hint:

Fresh water is naturally occurring water with low salt concentration, found in rivers, lakes, ponds, and streams. It comes from precipitation like rain and snow.

Answer 1

The Correct Option is D

We need to identify the correct term for rain water that flows into rivers, lakes, and ponds.

Step 1: Understand the water cycle and terminology.
Rain water follows different paths after precipitation:
- Some water infiltrates into the ground and becomes groundwater
- Some water flows over the land surface into rivers, lakes, and ponds - this is called surface runoff
- The water in rivers, lakes, and ponds is generally referred to as fresh water

Step 2: Analyze each option.
- (A) oceanic — Incorrect. Oceanic refers to oceans, which contain salt water, not rain water flowing into rivers.
- (B) ground water — Incorrect. Groundwater is water that seeps into the ground, not water that flows into rivers, lakes, and ponds.
- (C) dorsal burn — Incorrect. This is not a standard term in hydrology. "Dorsal" means relating to the back, and "burn" can mean a stream in some contexts, but combined it is not correct.
- (D) fresh water — Correct. Rivers, lakes, and ponds contain fresh water, which comes from rain and is characterized by low salt content.

Step 3: Conclusion.
The rain water that flows into rivers, lakes, and ponds is called fresh water.
Final Answer: (D) fresh water
