Solutions
Statement 1 is correct. Two major forms of clouds are stratiform and cumuliform. Stratiform clouds have a layered or sheet-like appearance, while cumuliform clouds have a puffy, cotton-like appearance.
Statement 2 is correct. According to the altitude, clouds are classified as high clouds, middle clouds, and low clouds. This classification is based on the altitude at which the clouds form in the atmosphere.
Statement 3 is incorrect. Stratus, nimbostratus, and stratocumulus are types of low clouds, not high clouds. Stratus clouds are uniform and cover the sky like a blanket, nimbostratus clouds are associated with steady precipitation, and stratocumulus clouds have a low, lumpy appearance.
Statement 4 is correct. Clouds with "nimbo" attached to their name, such as nimbostratus, are known to produce precipitation. "Nimbo" indicates that the cloud is capable of producing rain or other forms of precipitation.
Hence, Option B is correct.
