Which phenomenon refers to the slowing of wind due to the friction of Earth's surface?

• A. Coriolis Effect
• B. Hadley Cells
• C. Trade Winds
• D. Friction

Answer: (D)

The phenomenon that refers to the slowing of wind due to the friction of Earth's surface is friction. As wind moves across the surface of the Earth, it encounters various obstacles such as trees, buildings, and terrain variations, which create resistance. This resistance is what slows down the wind and is described as friction. It plays a crucial role in determining wind speed and direction close to the Earth's surface, making it an integral factor in understanding local weather patterns and the overall behavior of the atmosphere.

In contrast, the Coriolis Effect describes how the rotation of the Earth affects the movement of air and water, causing them to curve rather than move in a straight line. Hadley Cells refer to large-scale wind patterns that influence climate and weather across subtropical regions, while Trade Winds are specific prevailing winds that occur in tropical regions. These concepts are related to atmospheric dynamics but do not specifically address the impact of surface friction on wind speed.
