Which of the following INCORRECT about cirrus clouds?a) They formed at...
Cirrus clouds are thin and detached clouds that form at high altitudes. They are composed of ice crystals and are typically white or light grey in color. However, option C states that they are white and grey in color, which is incorrect.
Explanation:
Cirrus clouds are high-level clouds that form above 20,000 feet (6,000 meters) in the atmosphere. They are often found in the upper troposphere and the lower stratosphere. These clouds are composed of ice crystals due to the extremely cold temperatures at these altitudes.
Cirrus clouds are characterized by their thin and wispy appearance. They have a fibrous or hair-like structure, which gives them a unique appearance in the sky. These clouds are often described as being "feathery" or "curly."
Although cirrus clouds are typically white or light grey in color, their appearance can vary depending on several factors such as the angle of the sun, the presence of other clouds, and the size and shape of the ice crystals within the cloud. Under certain lighting conditions, cirrus clouds can appear pink, orange, or even purple.
Cirrus clouds are commonly associated with fair weather conditions, but they can also indicate the approach of a warm front or an upper-level disturbance. They are often the first sign of an approaching weather system.
In summary, cirrus clouds are thin and detached clouds that form at high altitudes. They are composed of ice crystals and can appear white, light grey, or even have a tint of color depending on various factors. Option C, which states that they are white and grey in color, is incorrect.
