Precipitation. Usually it is rain, but it could be sleet, snow, or hail.
The moisture in a cloud that is heavy enough to fall back to Earth primarily consists of water droplets or ice crystals that have coalesced to form larger particles. When these droplets grow to a size of about 0.5 millimeters or more, they become heavy enough to overcome the updrafts in the cloud and begin to fall as precipitation, such as rain or snow. This process is influenced by factors like temperature, humidity, and cloud dynamics.
Cloud droplets are tiny water droplets that form in the atmosphere when water vapor condenses around small particles, such as dust or salt, known as cloud condensation nuclei. These droplets are typically about 10 to 15 micrometers in diameter and can coalesce to form larger droplets, eventually leading to precipitation. They play a crucial role in the Earth's weather and climate systems by influencing cloud formation, reflectivity, and the hydrological cycle.
== == Very simply, a cloud is "FOG" that is above the Earth's surface, rather than in contact with the ground.Clouds and fog are one and the same thing, very tiny droplets of condensed water vapor, so small that they do not have enough weight to fall to the Earth, and consequently they just float around in the air. IF and when enough of these droplets of condensed water vapor, collide and stick together, they become heavy enough for gravity to cause them to fall to Earth, and that is what we call rain. Other forms of precipitation occur when the vapor (or rain) is exposed to colder temperatures. === ===Clouds are formed when water vapour in the air is cooled and condenses as part of the water cycle. Clouds consist of billions of tiny water droplets (and even ice crystals) floating in the sky and appear in a variety of shapes and sizes depending on how and where they formed.I found this answer at http://www.rcn27.dial.pipex.com/cloudsrus/clouds.HTMLHope this helps.
Water vapor in the atmosphere condenses into liquid water droplets as it cools and reaches saturation. When these droplets become large enough, they fall from clouds as precipitation such as rain or snow due to the force of gravity pulling them towards the Earth's surface.
The term that describes the droplets of water that condense on aerosols in the sky is "cloud droplets." These droplets form when water vapor in the atmosphere cools and condenses around tiny particles, known as aerosols, which serve as nuclei for the condensation process. This phenomenon is essential in cloud formation and plays a crucial role in the Earth's weather and climate systems.
When cloud droplets combine to form larger drops, they fall to the Earth as rain.

When cloud droplets combine to form larger drops, they become heavy enough to overcome the uplift in the atmosphere and fall to Earth as precipitation (rain or snow). This process is known as coalescence, where smaller droplets collide and merge to form larger drops due to gravity.

When liquid water droplets are big enough to fall to Earth, we call it rain.
Cloud droplets fall to Earth as precipitation when they grow large enough to overcome air resistance. This can happen when they coalesce into larger droplets or freeze into ice crystals. Gravity then pulls them down as rain, snow, sleet, or hail.
Why do the clouds droplets not fall to the earth
The moisture in a cloud that is heavy enough to fall back to Earth primarily consists of water droplets or ice crystals that have coalesced to form larger particles.

Evaporation: Water from the lake is heated by the sun and turns into water vapor, rising into the atmosphere. Condensation: The water vapor cools and condenses into tiny water droplets, forming clouds. Precipitation: When the water droplets in the cloud combine and become heavy enough, they fall back to the Earth's surface as rain.
By definition, a cloud is microscopic water droplets. Brought down to earth level, a cloud is called "fog" - which is the same thing: microscopic water droplets.
Rain falls to the ground from clouds when water droplets in the clouds combine to form larger droplets that become heavy enough to fall due to gravity.
they get bigger because the water droplets are cold and there is also water vapour in the air which is hotand when they meet the water vapour changes back to water droplets which then combine with the water droplets falling from the thunder cloud!!
