Which of the following winds is considered the weakest according to the Beaufort Wind Scale?

The Gentle Breeze is considered the weakest on the Beaufort Wind Scale, which categorizes wind intensity based on observable effects on the environment. A Gentle Breeze is defined as having wind speeds of approximately 8 to 12 miles per hour (13 to 20 kilometers per hour). At this level, the wind causes leaves to rustle and small twigs to move, but it does not significantly impact larger branches or structures.

In contrast, a Fresh Breeze, Strong Gale, and Storm all indicate progressively stronger wind speeds with more pronounced effects on the environment. A Fresh Breeze typically has a wind speed of 13 to 18 miles per hour, meaning it can cause larger branches to sway, while a Strong Gale can generate wind speeds of 39 to 46 miles per hour, capable of causing structural damage and uprooting trees. A Storm is characterized by even higher wind speeds, leading to dangerous conditions. Thus, the Gentle Breeze, being the weakest, is the correct answer in this context of the Beaufort Wind Scale.
