👉 The word 'Cloud B' refers to a specific part or shape of a cloud, often defined as having two layers that overlap one another in a spherical formation called a "cup." This type of cloud often forms when ice crystals from the Earth's atmosphere combine with water vapor and condensation. Clouds with this characteristic are commonly seen during periods of low pressure and high moisture levels, such as at the surface of oceans or on the surface of clouds in the sky.
