How is Sleet formed? O O when the falling snow reaches the layer of warm air, it melts. Then it hits the layer of cold air just above Earth's surface and refreezes O forms from thunderstorms towering high into the sky O It is caused when falling snowflakes melt through a warm layer of air high in the atmosphere to become rain O when the air in the clouds is at 32 °F (0 °C)
Answers
Answer:
Sleet
Sleet is type of precipitation distinct from snow, hail, and freezing rain. It forms under certain weather conditions, when a temperature inversion causes snow to melt, then refreeze.
Sometimes the weather forecast warns of “sleet,” rather than snow. When meteorologists in the United States use this term, they are referring to tiny ice pellets (the size of a pea, at most) formed when falling snow melts then quickly refreezes. (In the United Kingdom, sleet usually refers to a wintry mix). These pellets typically bounce as they hit the ground. Sleet can be dangerous, quickly coating the surface of roads and making driving hazardous.
Sleet Forms in Layers of Air (Warm above Cold)
To understand how sleet forms, it helps to know how snow forms.
The air closest to Earth’s surface—the layer where weather happens—is called the troposphere. In general, the higher you go in the troposphere, the colder the air becomes.
Answer:
(iv) when the air in the air in the clouds is at 32°F (0°C)
Explanation:
During formation of precipitation, if temperatures are at or below freezing, 0°C (32°F), at cloud level, water in the air freezes into ice crystals, and the crystals stick together to make snow. This phenomenon happens very fast, and the result is tiny ice pellets called sleet.
