What type of clouds are high and wispy?

1. Cumulus Clouds

2. Stratus Clouds

3. Cirrus Clouds

4. Nimbostratus Clouds

The correct answer is: Cirrus Clouds

Cirrus clouds are high-altitude clouds that are characterized by their thin, wispy appearance. They typically form at elevations above 20,000 feet and are composed mostly of ice crystals due to the low temperatures at those heights. Their delicate and feathery look often indicates that the weather is fair, but they can also signal changes in the weather, such as an approaching storm, as they may thicken into more significant cloud types. Cumulus clouds are fluffy and typically associated with fair weather but are not high or wispy. Stratus clouds appear as uniform gray layers covering the sky and are usually lower in altitude. Nimbostratus clouds are thick, dark clouds associated with continuous precipitation and are also lower in the atmosphere. Thus, cirrus clouds are the only clouds in the list that are both high and exhibit a wispy formation.
