Question

Which of the following is the most appropriate unit to describe the rate at which water flows over Niagara Falls?

a) Gallons per minute
b) Cubic meters per second
c) Liters per hour
d) Kilograms per day

Answer 1

The rate at which water flows over Niagara Falls is best described in cubic meters per second (m³/s), as it is the SI unit for large flow rates.

Step-by-step explanation:

The most appropriate unit to describe the rate at which water flows over Niagara Falls is cubic meters per second (m³/s). This is because the flow rate of such a massive volume of water is best represented in a unit that conveys the scale appropriately. The SI unit for flow rate is m³/s, which is a commonly used metric unit when discussing large flow rates such as rivers or waterfalls.
