Final answer:
A deposit of ice crystals formed by the freezing of supercooled cloud droplets on cold surfaces is known as frost, created through a process called deposition.
Step-by-step explanation:
The deposit of ice crystals formed by the freezing of supercooled cloud droplets on objects whose surface is below freezing is known as frost. This occurs through a process called deposition, which is the reverse of sublimation. In deposition, gaseous substances condense directly into the solid state without passing through the liquid phase.
In the atmosphere, this is often seen when ice forms on surfaces during cold conditions. To induce rain, methods like cloud seeding use substances like silver iodide or dry ice to provide nuclei around which water droplets can aggregate and freeze, forming larger particles that can then precipitate as rain or snow.
A deposit of ice crystals formed by the freezing of supercooled cloud droplets on objects whose surface temperature is below freezing is called frost. Frost is formed through a process called deposition, which is when gaseous substances condense directly into the solid state, bypassing the liquid state.
This occurs when the temperature of an object is below the dew point temperature and moisture in the air condenses as ice crystals on the object's surface.
