Which of the following statements with reference to Sleet is/are correct?
1. Sleet is frozen raindrops and refrozen melted snow-water
2. It occurs when a layer of air with the temperature below freezing point overlies a warm layer near the ground surface
Select the answer using the code given below:
1. Sleet is frozen raindrops and refrozen melted snow-water
2. It occurs when a layer of air with the temperature below freezing point overlies a warm layer near the ground surface
Select the answer using the code given below:
Options
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Correct answer
A. 1 only
Step-by-step solution
Sleet is defined as frozen raindrops and refrozen melted snow-water. Thus, statement 1 is correct.
For sleet to form, a layer of warm air (above freezing point) must overlie a subfreezing layer of air near the ground. Snow falls through the warm layer, melts into rain, and then refreezes into ice pellets as it passes through the cold layer near the ground. Statement 2 incorrectly states that a freezing layer overlies a warm layer near the ground. Thus, statement 2 is incorrect.
