Formation of snow occurs if the cloud temperature is:
-
A.
Equal to the freezing point
-
B.
At the freezing point
-
C.
Just above the freezing point
-
D.
Below the freezing point
Correct Answer:
D. Below the freezing point
Explanation:
Formation of snow occurs when the atmospheric temperature within a cloud is below the freezing point (0°C or 32°F). In these conditions, water vapor undergoes deposition, turning directly into ice crystals around microscopic particles like dust or silver iodide. While snow can fall through warmer air layers near the ground, the initial crystallization process requires sub-zero temperatures to ensure the moisture transitions into a solid state rather than liquid rain.
