Oct 19, 2023 · Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated , or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud.
What Is Precipitation? | NOAA SciJinks – All About Weather
Dec 5, 2024 · Rain: Rain made of liquid water droplets falls when temperatures in the air and at the surface are above freezing (32°F, 0°C). Rain can start as water droplets or ice crystals in a cloud but always falls as liquid water.
Rain - Wikipedia
Rain is water droplets that have condensed from atmospheric water vapor and then fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth.
Precipitation types - Wikipedia
Precipitation can fall in either liquid or solid phases, is mixed with both, or transition between them at the freezing level. Liquid forms of precipitation include rain and drizzle and dew.
Rain | Definition & Facts | Britannica
6 days ago · Rain, precipitation of liquid water drops with diameters greater than 0.5 mm (0.02 inch). When the drops are smaller, the precipitation is usually called drizzle. Concentrations of raindrops typically range from 100 to 1,000 per cubic meter (3 to 30 per cubic foot); drizzle droplets usually are more numerous.
Precipitation - Wikipedia
Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice. Mixtures of different types of precipitation, including types in different categories, can fall simultaneously.
Precipitation - Education | National Geographic Society
Oct 19, 2023 · Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the earth. It comes in many forms, like rain, sleet, and snow. Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle.
Precipitation Types - Skyview Weather
Rain is the most common type of precipitation, taking the form of liquid water. The rain development process begins when atmospheric water vapor condenses on particles of dust, pollen, smoke, and pollution, to form tiny water droplets.
Chapter 7: Precipitation Processes
The most important factor in raindrop production is the liquid water content of a cloud. Assuming the cloud has sufficient water, other factors that affect raindrop production are: thickness of the cloud; strength of updrafts within the cloud; cloud drop distribution of sizes; and difference in electric charge of the droplets and the cloud itself.

Rain is the liquid form of water that falls from the sky in drops. Rain fills lakes, ponds, rivers, and streams. It provides the fresh water needed by humans, animals, and plants. If too much rain falls, however, dangerous flooding may happen. Rain is a part of Earth’s endless water cycle.
