To determine which two types of clouds indicate fair weather, we can analyze the characteristics of each cloud type.
1. Cirrus clouds are thin, wispy clouds that are high in the atmosphere. They are made up of ice crystals and often appear feathery or streaky. Cirrus clouds are usually indicators of fair weather because they form in stable atmospheric conditions.
2. Cumulus clouds are big, white, fluffy clouds that have a flattened base and a rounded shape on top. They are commonly associated with fair weather since their development is a sign of vertically rising warm air and stable atmospheric conditions.
Based on these characteristics, the correct answer is A. cirrus and cumulus clouds indicate fair weather.
