Question 1209Navigation General

The correct answer is B) 6,500 to 20,000 feet (1981 to 6096 meters). Middle clouds, also known as altostratus and altocumulus clouds, are located in the middle troposphere, above the low-level clouds and below the high-level clouds. The bases of these middle clouds are typically found at altitudes between 6,500 and 20,000 feet (1981 to 6096 meters). The other options are incorrect because: A) 3,000 to 6,500 feet (914 to 1981 meters) is the altitude range for low-level clouds. C) 10,000 to 35,000 feet (3048 to 10,668 meters) is the altitude range for high-level clouds. D) 20,000 to 60,000 feet (6096 to 18,288 meters) is the altitude range for the upper troposphere and stratosphere, which is above the middle clouds.
