Cloud drops
When cloud droplets combine to form larger drops, they fall to the Earth as rain.
This process is known as condensation, where water vapor in the air transforms into liquid water droplets on a surface. The dust particles act as nuclei for the water vapor to gather around and form droplets. This phenomenon is common in the atmosphere and can lead to the creation of clouds or fog.
Air and water form a cloud.
precipitation
ALL clouds are made out of water drops, though some clouds like cirrus are made of ice.
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.
the water cycle
because the water spreads out and the air pushes them to each other and forms drops.
Water vapor (that has evaporated) condenses into cloud droplets in the cooler atmosphere. Many of these droplets form clouds. When enough water molecules with the clouds form together, they become too heavy for the upward flowing air to keep them in the cloud. The droplets then fall back down to earth as precipitation, rain being the most common form.
These are called dew drops. They form when the temperature of the surface cools down causing water vapor in the air to condense and form small droplets of water. Dew is more likely to form on clear, calm nights when the temperature drops close to the dew point temperature.
