Why is rain called precipitation?
Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor (reaching 100% relative humidity), so that the water condenses and “precipitates” or falls. Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud.
What is the geographical term for rain?
Precipitation is any form of moisture which falls to the earth. This includes rain, snow, hail and sleet. Precipitation occurs when water vapour cools. When the air reaches saturation point (also known as condensation point and dew point) the water vapour condenses and forms tiny droplets of water.
Why is convection called 4 o’clock rain?
In the equatorial regions, convectional rainfall is received almost daily in the afternoon. It generally happens regularly at 4 p.m. throughout the year. For this reason it is called 4’o clock rainfall. In the late afternoon the clouds burst into a heavy downpour often accompanied by thunder and lightning.
Can it rain without clouds?
Because rain forms when droplets of condensed moisture grow large enough to descend quickly into the air, their absence can make it impossible for rain to occur. That means if there are no clouds overhead, rain cannot happen as well.
What are the side 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.
How old is the water on Earth?

Does water expire?
Though water itself doesn’t expire, bottled water often has an expiration date. This is because plastic can begin to leach into the water over time, contaminating it with chemicals, such as antimony and bisphenol A (BPA) ( 5 , 6 , 7 ).
What was the first color invented?
Artists invented the first pigments—a combination of soil, animal fat, burnt charcoal, and chalk—as early as 40,000 years ago, creating a basic palette of five colors: red, yellow, brown, black, and white.
