Sky with clouds 4K - Scenic Relaxation Film With Calming Music
Clouds are products of water vapor condensation suspended in the atmosphere, visible in the sky with the naked eye from the surface of the Earth and near-Earth space. In a broad sense, a cloud is a collection of individual particles of a substance in a certain volume.
Clouds are made up of tiny droplets of liquid water and/or water ice crystals called cloud elements. Droplet cloud elements are observed when the air temperature in the cloud is above −10 °C. When the air temperature in the cloud is from −15 to −10 °C, the cloud has a mixed composition (drops and ice crystals). When the air temperature in the cloud is below -15 ° C - only crystalline. Water vapor is not the main component of clouds.
