are these correct?

Yes, Good Job! High Five

Yes, both of your answers are correct!

To determine the answer to the first question, you need to understand cloud prefixes. Clouds are classified based on their altitude and appearance. The prefix "alto" is used for clouds that form at mid-level altitudes, typically between 6,500 and 20,000 feet. Therefore, when you observe a cloud at an altitude of 10,000 feet, the correct prefix would be "alto," as it falls within the mid-level range.

To answer the second question, you need to know the different types of clouds. Among the options given, "stratus" is the cloud type that is best described as sheets or layers that cover much or all of the sky. Stratus clouds are low-level clouds and are generally uniform and featureless. They often bring overcast or gray sky conditions. Therefore, the correct answer is "b. Stratus."
