Question: 1 / 400

What characteristic do altostratus clouds share?

They are typically found below 6,000 feet

They appear as a thin veil of white or grey clouds

Altostratus clouds are characterized by their uniform appearance, typically appearing as a thin veil of white or grey clouds that can cover the sky. They often create a diffuse light, which is generally softer when compared to other types of clouds. This characteristic is important in distinguishing altostratus from other cloud types that might exhibit more defined structures or darker hues.

While altostratus clouds can cover the sky and can lead to precipitation, they do not typically form the towering shapes associated with types of clouds such as cumulus or cumulonimbus. Additionally, while they can block sunlight to some extent, they do not usually obscure it completely as darker cloud types might. Their typical altitude is also generally higher than 6,000 feet, placing them in the mid-altitude category of clouds. Thus, the defining trait of these clouds being a thin veil of white or grey is what makes the answer correct.
