Why do water droplets come together?
The point at which air holds as much water vapor as it can without liquid water forming (condensation) is called the saturation point. When air cools, the amount of water vapor it can hold decreases. With sufficient cooling, the air reaches saturation and small cloud droplets begin to form.
When cloud droplets combine to form larger drops they fall to earth as?
Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle. Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth.
What happens to water droplets after precipitation?
The droplets freeze and form hailstones. The hailstones grow as more water droplets freeze onto them and eventually fall to the ground. Sleet: The icy precipitation known as sleet forms when a thin layer of warmer air comes between layers of cold air.
How are water droplets in the clouds formed?
Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air. That means some of the liquid water in the towel or bowl changed into an invisible gas called water vapor and drifted away into the atmosphere.
How do clouds form in the water cycle?
What is all forms of water that fall from clouds?
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail.
What do the water droplets represent?
When the drops collide with each other they form bigger and bigger drops of water and represent clouds. When the clouds get enough water in them that they can no longer hold it, the water droplets drop down as rain onto the earth.
How does a cloud fill up with water?
The water drops and ice crystals that make up a cloud are floating not because they are soaked up by some sponge-like material that is holding them in place. Rather, the water drops and ice crystals that make up a cloud float because they are so small that the air resistance balances out gravity.
How does rain fall from clouds?
Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
