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 does rain occur on the earth?
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.
What are the 3 reasons for rain to fall?
There are 3 main types of rainfall: relief, frontal and…
- Frontal rainfall occurs when warm air is forced to rise over cold air.
- The moisture in the warm air condenses as it cools which causes clouds and rain.
What happens to rain when it falls to Earth?
When it rains, where does it go? Once on the land, rainfall either seeps into the ground or becomes runoff, which flows into rivers and lakes. … Water falling on uneven land drains downhill until it becomes part of a stream, finds a hollow place to accumulate, like a lake, or soaks into the ground.
How long does heavy rain usually last?
1/10 (0.10) of an inch of rain – A light rain for 30-45 minutes, moderate rain for 10 minutes or heavy rain for 5 minutes. Small puddles would form but usually disappear after a short while. 1/4 (0.25) of an inch of rain – A light rain for 2-3 hours, moderate rain for 30-60 minutes or heavy rain for 15 minutes.
How long does it take a raindrop to fall to earth?
Its difficult to give an exact figure as the height at which raindrops fall and their size vary widely, but given that raindrops fall at an average speed of around 14 mph and assuming a cloud base height of around 2,500 feet, a raindrop would take just over 2 minutes to reach the ground.
Which is stronger rain or showers?
Showers, also known as rain showers, have a shorter duration than rain. … Compared to rain, showers cover a smaller area but can be more intense. Cumulonimbus clouds (thunderstorm clouds) produce the heaviest rainfalls. Showers from stratocumulus clouds (not as puffy) tend to not be so heavy.
Does it rain diamonds on Saturn?
On the planet of the rings the atmosphere holds a treasure: real showers made from diamonds. Scientists believe that about 10 million tons of these stones are produced in its atmosphere each year. …
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.
Why is rain important for us?
Rainfall is very important for the survival of plants and animals. It brings fresh water to the earth’s surface. If rainfall is less, there is water scarcity which sometime causes drought like situation. If there is excess rain, floods take place which make the life of the affected people miserable.
