Water vapor whose temperature has dropped below the freezing point is described as?

Water vapor whose temperature has dropped below the freezing point is described as?

• A. Supercooled
• B. Saturated
• C. Freezing rain
• D. Source region

Answer: (A)

Supercooled means a liquid is kept in liquid form even below its normal freezing temperature. In the atmosphere, water can remain as liquid droplets at temperatures below 0°C instead of turning into ice. Those supercooled droplets are unstable and will freeze upon contact with a surface, which is why freezing rain can occur when they hit cold surfaces. The other terms don’t describe a state of water that’s below freezing: saturated refers to how much water vapor the air can hold, freezing rain describes a precipitation type, and a source region is simply where air masses originate.
