  1. Low clouds have a higher likelihood of producing precipitation as they normally consist of supercooled droplets and liquid water droplets, except in the course of winter when they are largely composed of ice crystals. They are closer to the ground in which case they are subject to immense atmospheric instability and moisture, unlike the middle and high level clouds.

  2. A. Stratus b. Cirrus c. cumulus d. stratus e. cumulus f. cirrus

  3. Clouds may form in varied altitudes, while fog only forms in instances where the air close to the ground cools sufficiently to turn the vapor to liquid water. Clouds, on the other hand, form when warm and moist air rises, expands and cools.

  4. Radiation fog forms in clear night skies than in cloudy ones since such nights would allow for the heat that the earth’s surface absorbed in the course of the day to be radiated into space.

  5. A. Advection fog B. Frontal Fog C. Upslope Fog

Advectionfog results from condensation, where warm moist air moveshorizontally over a cold surface. Frontal fog, on the other hand,forms in instances where warm raindrops evaporate to cooler, drierlayers of air close to the water bodies. The upslope fog forms ininstances where moist air is pushed up by light winds to amountainside or hillside level that allows for its saturation andcondensation.

  1. This type of fog is freezing fog.

  2. This type of fog is upslope fog.

  3. It takes around a million cloud droplets for a single raindrop to be delivered in instances where the relative humidity is sufficiently high. However, the absence of any other process would mean that only clouds would be available but no rain. The most natural process would involve coalescence of the minute droplets. This may, however, not be possible without ice which attracts water vapor as a result of increased pressure, thereby allowing for rapid growth of the crystal until it is heavy enough to fall.
