What happens to water which comes down as rain?
As the water vapor rises up in the air, it condenses, or starts to cool down and turns back into a liquid. Then, droplets of water start to stick together as clouds. When water drops fall from clouds, it is called rain. Sometimes the droplets freeze before they get to the ground and become hail, sleet, or snow!
What are the three things that happens to the water as rain forms?
Water continually evaporates, condenses, and precipitates, and on a global basis, evaporation approximately equals precipitation. Because of this equality, the total amount of water vapor in the atmosphere remains approximately the same over time.
Why is it possible for no rain to be falling from a cloud?
Most of the condensed water in clouds does not fall as precipitation because their fall speed is not large enough to overcome updrafts which support the clouds. For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus.
What is the record for most rain in one hour?

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 does rain occur in the water cycle?
Rain is droplets of water that are condensed as a result of evaporation that takes place during the water cycle which causes the formation of clouds. Hence, rains occur due to the formation of clouds.
Where does the rain water go after it leaves the ground?
Rainwater that becomes groundwater — water that is stored and moved through the ground by means of the water table (an underground region of highly-saturated earth that stores water) — moves into ponds and streams and eventually rivers and oceans where it evaporates and becomes part of the atmosphere.
Why do rain drops fall to the Earth?
It is caused when clouds (made of water vapor) absorb too much moisture. This causes the little drops of water vapor to bunch together into larger and larger drops (the process is called condensation). Eventually the drops get too heavy for the air to hold them up so they fall to the earth: rain.
What causes rain to form in liquid form?
Rain is precipitation in liquid form as a result of cloud formation. Rainfall in a region depends upon the density of clouds formed, influenced by temperature and pressure.
