Why do waterfalls never dry up?
152514
Waterfalls normally don't dry up because the stream that feeds them doesn't dry up. However, some of the waterfalls in the Alligator Rivers region of the Northern Territory of Australia such as the Jim Jim Falls and the Twin Falls have been known to dry up during the dry season and start again in the wet season as the creeks that feed them resume running.

The reason is because there is no atmosphere to retain the water. If you did a slow process with water you could eventually get a green house going. It would take a 1000 years and its not really worth it. This would use trillions of tax dollars of money that could possible never work.\nPlus we need trees once there becomes somewhat of a green house to produce oxygen to counter act the CO2.

WEll where will water fall. i mean when ever i saw water its on sealevel then where the hell will water fall. yeah water falls but from clouds. There is a word gravity. which plays important role. else after birth u wud have not fallen down. u wud be somewhere in sky.

because wetlands (swamps) act like big sponges and they soak up all the water. that's why we have worse floods in areas where the natural wetlands have been paved over because there aren't wetlands to soak up the water anymore.

When it reaches the earths surface it either soaks into the ground, eventually ending up in acquifers. Or it runs off into creeks and rivers, eventually reaching the ocean. It then is evaporated back into the atmosphere.  It is also used by plants and animals.

it usually becomes dry, but nothing damaging happens

You could be retaining water.

Also if there is a landslide say beside a damn... then a flood could happen , if the dam is takn out with the land slide.. then all the water held back by the dam will be released resulting in a flood.

No. They are far too large for any single or even series of rainstorms to have any noticeable affect on the water level. However, if our weather patterns started to change significantly and over many years we had more and more rain, then the water level could rise. It would be a slow process.

The clouds hang in the air due to buoyancy (density of water vapour is less than air). At higher altitudes the air becomes thinner and force of buoyancy is lesser. so they cant hang at higher altitudes.

isn't liquid suppose to get in the thing?\n\nit sounds like an air dry outside will help if anything will

It is because the water is always flowing and changing the river.  The water brings new things from up stream and washes current things down stream.  You can never count on a river to be the same as it was the last time you stepped in it.

Because it's STILL being taught! How can you stop a creek from turning into a river, you have to slowly close off the source. Until then, it is something we have to overlook, practice against, and stick to our mission of being 1, not 2 or two.

Because settling only works if there is no chemical reation involved. All of the prticals of some substances will not settle out of water. like sugar. Even if they do the time frame needed to accomplish this is to long.

In order for it to rain, there needs to be a low pressure system over you as well..besides evaporation.  During the summer, low and high pressure belts move.  That's why some places that are dry all year have a really rainy season and normally rainy places get no rain during the summer.

They will remain suspended above the waterline due to surface tension unless you.......\n\n   (see below)

water on the ground, in oceans, lakes, etc. has enough energy to evaporate a little bit (all liquids have a "vapor pressure," which is higher the hotter it is).  eventually, there is too much water in the air at whatever air temperature it is, so the water re-liquifies and falls.  this can commonly happen when a warm front (warm air holds lots of water) is cooled by a cold front.
