Q:

When do rain clouds gather?

A:

Quick Answer

Rain clouds form when clusters of water droplets and crystallized, frozen water accumulate at high altitudes, and gravity causes this condensed water to fall as rain. The average size of one of these cloud droplets is miniscule, but if the droplets contain enough water, white clouds turn into rain clouds. The influence of gravity causes a droplet to turn into a raindrop and fall to earth.

Clouds form via the process of evaporation and condensation. When the temperature is warm, molecules of water are agitated, expanding the distances between them. Water molecules then switch form between liquid and vapor phases. When this happens, molecules leave a body of water, such as a lake or an ocean, and become water vapor, which rises into the air. The water vapor rises high up to form clouds, which are essentially large masses of tiny water droplets and crystallized water molecules. If the clouds get thick enough or high enough, the light from above does not make it through, leading to the gray or dark look of a rain cloud.

Snow, sleet, hail and lightning are also produced by rain clouds. The different shapes and sizes of clouds depend on the weather conditions under which they were formed.

    What are rain clouds called?

  • Q:

    How do clouds make rain?

    A:

    Precipitation occurs when moist air rises to cooler altitudes, condensing the water out of the air into droplets. Once these droplets become heavy enough, often by coalescing around motes of dust or other particles, they fall out of the cloud as precipitation. Without significant updrafts bringing more moisture to the cloud layer, the condensed water may remain light enough to stay aloft, which is why not every cloud brings rain.
