Question

How does sleet differ from snow?

Answer 1

Hint:As winter season comes we can see many cold-weather precipitations such as snow, sleet and freezing rain. Drizzle, rain, hail are other forms of precipitations found in nature.

Complete step by step answer:Precipitations are the formation of solid substances from solutions. Both sleet and snow are solid-water precipitations. They differ in their way of formation in the atmosphere. They also differ in density and macro structure.
Snow contains ice crystals in a flaky form. They have low unit density and mass. Their average density is $0.1g/cc$ . It is a very common way of precipitation that is found in regions of high altitude. It is a delicate crystalline substance. Snow is formed as a result of the nucleation reaction of water into small individual units of frozen water. They fall gently to the ground. Snow can be converted into rain. When temperature is much warmer at earth surface, snow may be converted into rain. Snow occurs usually when the temperature is equal to or less than $32$ Fahrenheit.
Sleet is directly frozen rain. Hence its mass is the same as that of a raindrop. Sleet is formed when rainfall passes through the air when the temperature is at subfreezing levels. It may freeze into ice before falling to the ground from the sky. Sleet can be said as a mixture of snow and rain.

Note:
The difference in temperature at different parts of the atmosphere is the reason for explaining the existence of various forms of cold- weather precipitations like snow, sleet, rain, freezing rain, hail etc.
