Cloud gathered in free air mass visibly. Water droplets ice crystals or a mixture of both comprising structure. Clouds are high from ground level. Consisting of a ground-level cloud layers are shallow fog is called.
Atmospheric water vapor that condenses and small water droplets usually 0.01 mm in diameter ice crystals form.Billions of cloud droplets and crystal structure called a combination form. Clouds reflect all visible wavelengths. It is usually white, but can also appear as gray or black. The cause of gray or black appearance, due to the thickness of the sunlight that they do not let it pass.
