The height of the bases of the middle clouds in the middle latitudes ranges from?

The height of the bases of middle clouds, specifically those classified as altostratus and altocumulus, typically ranges between 6,500 and 23,000 feet in middle latitudes. This range is consistent with standard meteorological guidelines that define these clouds, which are found at altitudes higher than low clouds but lower than high clouds.

Understanding the characteristics of each cloud type helps contextualize why this range is accurate. Middle clouds form in layers and usually indicate moisture in the atmosphere at moderate heights. Their formation process involves different temperature and moisture levels compared to low or high clouds, which is why their altitude range differs.

Other options either fall outside this recognized range or do not accurately represent the typical heights where middle clouds can be observed, reinforcing why the selected range provides the correct answer.
