What are two ways that rain can form?
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..
How rain is formed for kids?
Water is always moving; rain that’s fallen where you live may have been water in the ocean a couple of days before. The water vapor rises in the atmosphere and there it cools down and forms tiny water droplets through something called condensation. … These tiny droplets then turn into clouds.
What are the 4 types of rainfall?
The different types of precipitation are: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.
Why is rain so important?
With temperature, rainfall is perhaps the most important factor in defining climate. Excess rainfall can cause flooding and enormous property and crop damage. Still, a deficiency of rainfall can cause drought and crop failure. Rainfall is also the major source of energy that drives the circulation of the atmosphere.
Is rain natural?
Natural rain contain carbonic acid. When enough of the tiny cloud droplets clump together to form a larger water drop it may fall to the earth as “wet” acid precipitation including rain, snow, ice, sleet, or fog. … The final rain droplet has an average pH of 4.2 in the Northeast U.S.
How much is a lot of rain in a day?
Moderate rainfall measures 0.10 to 0.30 inches of rain per hour. Heavy rainfall is more than 0.30 inches of rain per hour. Rainfall amount is described as the depth of water reaching the ground, typically in inches or millimeters (25 mm equals one inch).
How can rain come?
Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. This vapour rises, cools, and changes into tiny water droplets, which form clouds. The water droplets in the clouds join together to form bigger drops.
What is rain made of?
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 caused Class 9?
Rain is formed by evaporation and condensation of water through water cycle. Acid rain is caused by the release of the gases like SO2 (sulphur dioxide) and NO2 (nitrogen dioxide) released from the emission of vehicles and combustion of fuels. These gases dissolve in rain water to form nitric acid and sulphuric acid.
What is rain for kids?
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.
Is rain water clean?
Most rain is perfectly safe to drink and may be even cleaner than the public water supply. Rainwater is only as clean as its container. Only rain that has fallen directly from the sky should be collected for drinking. … Boiling and filtering rainwater will make it even safer to drink.
