At the beginning of the cycle, sunlight heats up water on Earth’s surface. The heat causes the water to evaporate, or to turn into water vapor. This water vapor rises into the air. As the water vapor cools, it turns back into water, in the form of droplets.
How is rain formed short answer?
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.
How is rain made?
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. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one.
How is rain formed Wikipedia?
When wet onshore wind from the sea meets a mountain, hill or any other sort of barrier, it is forced to rise along the slope and cools. When the air temperature falls to its dew point, water vapour condenses to form clouds . ... The air cools and the water vapour condenses, forming rain drops.
How rain is formed explain all stages?
There are four main stages in the water cycle. They are evaporation, condensation , precipitation and collection. ... Condensation: This is when water vapour in the air cools down and turns back into liquid water. Precipitation: This is when water (in the form of rain, snow, hail or sleet) falls from clouds in the sky.
What are the negative effects of cloud seeding?
Risks or concerns like unwanted ecological changes, ozone depletion, continued ocean acidification, erratic changes in rainfall patterns , rapid warming if seeding were to be stopped abruptly, airplane effects, to name a few, may just not be bad enough to override the imperative to keep temperatures down.
Why does rain happen?
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. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one.
Which country rains most?

What is called rain?
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
What are the 4 types of rainfall?
- Rain. Most commonly observed, drops larger than drizzle (0.02 inch / 0.5 mm or more) are considered rain. ...
- Drizzle. Fairly uniform precipitation composed exclusively of fine drops very close together. ...
- Ice Pellets (Sleet) ...
- Hail. ...
- Small Hail (Snow Pellets) ...
- Snow. ...
- Snow Grains. ...
- Ice Crystals.
What is water cycle for kids?
The Short Answer: The water cycle is the path that all water follows as it moves around Earth in different states . Liquid water is found in oceans, rivers, lakes—and even underground. ... The water cycle is the path that all water follows as it moves around our planet.
Is it possible to make it rain?
Cloud seeding
What is a cloud seeding?
Cloud seeding is a weather modification technique that improves a cloud’s ability to produce rain or snow by artificially adding condensation nuclei to the atmosphere , providing a base for for snowflakes or raindrops to form.
Who invented cloud seeding?
Vincent J. Schaefer , a self-taught chemist who invented cloud “seeding” and created the first artificially induced snow and rainfall, died on Sunday at a hospital in Schenectady, N.Y. He was 87 and lived in Rotterdam, N.Y. Mr.
What are the positives of cloud seeding?
If cloud seeding is implemented, there will be increased harvesting and more food available from a wide variety of crops for the ever-growing human population . The process also has the potential to improve biomes, allow for more fertility and create more farming land and land that could be used to build better homes.
Is cloud seeding expensive?
He estimated ground-based cloud seeding costs as little as $4 per acre foot of water produced, while seeding by air is $75 per acre foot .
