The BOD POD is based on the same whole-body measurement principle as hydrostatic or underwater weighing - the previous gold standard of body composition testing, which requires complete submersion in a water tank. BOD POD Body Composition System to Descend On San Francisco's IHRSA Convention.
Clouds are made of tiny drops of water or ice crystals that settle on dust particles in the atmosphere. The droplets are so small-a diameter of about a hundredth of a millimetre-that each cubic metre of air will contain 100 million droplets.louds are usually produced through condensation-as the air rises, it will cool and reducing the temperature of the air decreases its ability to hold water vapour so that condensation occurs. The height at which dew point is reached and clouds form is called the condensation level.
Fog is a cloud in contact with the ground. Fog differs from other clouds only in that fog touches the surface of the Earth. The same cloud that is not fog on lower ground may be fog where it contacts higher ground such as hilltops or mountain ridges. Fog is distinct from mist only in its density. Fog is defined as cloud which reduces visibility to less than 1 km, where as mist is that which reduces visibility to less than 2 km. Fog is a cloud that is sitting on the ground or just above it. A cloud is made up of water droplets or ice crystals.
