Question

Which topography features may alter air flow and cause turbulence?

A. Aspect
B. Chutes
C. Drainages
D. Local terrain

Answer 1

Local terrain, including aspects like south-facing slopes in the northern hemisphere, as well as chutes and drainages, may alter air flow and cause turbulence due to changes in wind patterns and speed. So, the correct answer is option D.

Step-by-step explanation:

The topography features that may alter air flow and cause turbulence include local terrain, such as mountains and hills, which can affect wind patterns and create turbulent conditions. Aspects, particularly in the northern hemisphere where south-facing slopes are warmer and more prone to erosion, can also influence air flow.

Chutes and drainages can alter air paths by funneling or directing the flow of air in specific ways, leading to changes in wind speed and potentially causing turbulence. Therefore, the correct answer to which topography features may alter air flow and cause turbulence is D. Local terrain. So, the correct answer is option D.

Answer 2

The topographical features that can alter air flow and cause turbulence include aspect, chutes, drainages, and local terrain, with local terrain having the most comprehensive influence on wind patterns. Option D is correct.

Step-by-step explanation:

Topographical features that may alter air flow and cause turbulence include aspect, chutes, drainages, and local terrain. Aspect refers to the direction a slope faces, which can affect microclimatic conditions such as temperature and moisture. These conditions influence the plant communities that can thrive and their subsequent root systems, which can anchor soil and reduce erosion. Chutes are steep-sided valleys through which air can accelerate and become turbulent. Drainages, such as gullies and streams, can interrupt and divert airflow, leading to turbulence. Lastly, the local terrain itself, including variations in elevation and slope steepness, can disrupt and complicate airflow patterns.

In the context of the question, the correct answer would be D. Local terrain, as it represents the overall influence of regional surface features on wind patterns, including air flow and turbulence. The local terrain encompasses aspects like slope, aspect, and the existence of features like chutes and drainages that can all contribute to changes in wind patterns.
