The sun's energy evaporates water, and changes its phase to water vapor. The vapor rises into the atmosphere, and becomes clouds. When cloud droplets collide, they join together to form a larger droplet. As the process continues, the droplet eventually becomes too heavy and falls to earth as precipitation.
cooling
There are four main mechanisms for cooling the air to its dew point.
Adiabatic cooling occurs when air rises and expands. The air can rise due to convection, large-scale atmospheric motions, or a physical barrier such as a mountain.
Conductive cooling occurs when the air comes into contact with a colder surface, usually by being blown from one surface to another, for example from a liquid water surface to colder land.
Radiational cooling occurs due to the emission of infrared radiation, either by the air or by the surface underneath.
Evaporative cooling occurs when moisture is added to the air through evaporation, which forces the air temperature to cool to its wet-bulb temperature, or until it reaches saturation
it all begins with the earth's water cycle. the sun evaporates water from the earth, and it condenses into water vapor in clouds. eventually, the clouds will undergo percipatation and once more return to the earth's surface.
basically it is caused by our earth's own water system. almost like the earth's way of recycling water.
Water vapor condenses into tiny droplets in the atmosphere to form clouds. When these droplets come together and grow in size, they eventually become heavy enough to fall as rain.
Rain can form through the process of condensation, where water vapor in the air cools and changes into liquid water droplets. Rain can also form through the collision and coalescence of water droplets in clouds, where smaller droplets merge together to form larger droplets that eventually fall as rain.
airRain are water droplets that fall from the sky.If it is very cold, or there are layers of vary cold air that the rain passes through on the way down, the water droplets can become snow or balls of hail.
That is called rain. Rain is formed when water droplets in clouds combine to create larger droplets that fall to the ground due to gravity.
When the cloud reaches saturation level and the air can no longer hold the water vapor, small water droplets in the cloud combine to form larger droplets. When these droplets become heavy enough, they fall to the ground as precipitation, such as rain or snow.
When the water vapour in clouds merge and become droplets, they will fall as rain. Two basic reasons are the droplets have become too heavy, and gravity.
Temperature typically needs to go down in order to create rain. As warm air rises and cools, it condenses into water droplets, forming clouds. When these water droplets come together and become heavy enough, they fall as precipitation in the form of rain.
Rain forms when water droplets in clouds combine and grow large enough to fall to the ground. These water droplets typically come from condensation of water vapor in the air, which collects in the clouds and eventually falls as rain when the droplets become heavy enough.
Individual droplets are so small, that they can stay suspended in the air. If the droplets combine into larger drops that are too heavy to stay suspended, they fall as raindrops.
The basic rule is what goes up must come down in the case of rain water vapour in the air condences as a result of cooling to form droplets which eventualy have to fall down.
how do droplets become heavy enogh so that the droplets fall as rain and snow
Because when the observer is between the sun and the rain droplets the sun hits the rain droplets and then the rain droplets bend and form the colours.
Rain forms when water droplets in clouds combine and grow in size. When these droplets become too heavy to remain in the air, they fall to the ground as precipitation. The size of the rain droplets can vary depending on the atmospheric conditions and the temperature of the air.
