Question

1. The water of rivers and streams is _________.

A: cold and fast moving


B: warm and slow moving


C: cold and slow moving


D: warm and fast moving

Answer 1

The correct answer is A: cold and fast moving, as rivers and streams are typically cold and fast moving at their point of origin due to a narrower channel and faster current.

Step-by-step explanation:

The water of rivers and streams at their point of origin, which is referred to as source water, is usually cold, low in nutrients, and clear. The channel is narrower, and thus, the current is often fast moving in these headwater streams. Based on this information, the correct answer to the question 'The water of rivers and streams is _________' would be A: cold and fast moving. As the river or stream moves away from the source, it widens and slows down, and the water becomes warmer and may carry sediment making it less clear.
