What are three sources from which permanent streams get their water?

permenant streams can get their water from underground springs/aquifers, melting ice or snow from high elevation mountains or glaciers, or the drainage of a large landmass.

a tributary or a distub thingy

Yes, there are also some tidal rivers.  The Danube is one I can think of.

The main parts of a river include a channel, in which the water flows, and a floodplain—a flat region of a valley on either side of the channel. Through the channel and floodplain, water and sediment—material transported by the river, such as sand and silt—are transferred from ridges and mountains to the sea or to a lake. A river starts on hillsides as small channels, or rills. The rills combine to make larger channels or tributaries that eventually come together, forming distinct streams. The largest channels formed by this convergence of tributaries are rivers, and they can carry large quantities of fresh water and sediment across continents.

Tap water.\nSoap breaks down the surface tension.

it depends on the properties of water extracted at that place,it could be any thing for obvious reasons.it depends on H+ ions..it depends on acidic property of soil, pollution, type of pollutio,wher that water is coming from like upstream properties.its hard to say.

Typically, headwaters only experience recharge, but a local depression in the land surface can create a window into the groundwater, usually in the form of a lake or swamp.  Water here can flow downstream, and thus can add to discharge.

We never get new water here on earth..it's just recycled. The water cycle defined is "Transition and movement of water involving evaporation, transpiration, condensation, precipitation, percolation, runoff, and storage."\n\nWater falls in the form of precipitation (snow, rain, etc). Some of it seeps into the ground that makes up our water aquifers (perculation), some is in the form of runoff (rivers, streams), eventually water makes its way to lakes, ponds, oceans, etc and is stored. Some water is taken up by plants and is stored there. It leaves "storage" when the water evaporates and through transpiration in plants (plants lose water through their leaves which is why they seem especially prone to wilting on a hot windy day).\n\nCondensation is when water goes from a gaseous state back to a liquid state. An example of this putting your breath on a cold window or mirror and watching the water droplets form.\n\nHope this helped. It's a simplified explanation, but it will get you started.

Rivers & streams are parts of drainage basins (aka watersheds). This means that they drain most of the surface water from an area.\n\nWhen it rains very heavily, it runs off & goes into the rivers & streams b/c they are lower in elevation. This is called surface runoff.\n\nRivers are only capable of handling a certain amount of water at a time. When it reaches flood stage it will overflow it's banks.\n\nAlthough it is possible for a lake to flood, more than likely it will not. It is less likely to get all the surface runoff from the surrounding area.\n\nOceans are not going to flood unless sea level rises. There is no real "normal" flood stage for oceans. Over time they transgress & regress in response to climate change. Water is constantly being evaporated from the oceans as well.\n\nMost of our precipitation comes from water vapor that was evaporated from the oceans. This is simply b/c oceans cover the majority of the planet.\n\nHope this helps.

my guess is the oceans, and other bodies of water, i.e. lakes, rivers, and streams!

2 sources of water, Comets & Subterrerain.\n\nWhat % of ponds does not make a question.

New York City's water comes from lakes in the mountains of upstate New York.  It is held in resevoirs (such as the Croton Reservoir) north of the city and transported throughout the city via a tunnel system.

In the water cycle, water falls to the earth in the form of precipitation.  Plant roots absorb the water, which is then transported through the xylem vessels to the leaves.  There, photosynthesis takes place.  Each water molecule is split up, forming hydrogen ions, oxygen, and electrons.  The electrons are used to create ATP for the dark reactions.  In end, a three-carbon sugar is formed, which combines with another three-carbon sugar to form glucose.  Besides photosynthesis, water seeps into the ground and bodies of water.  It stays there for organisms to use.  Much of it eventually evaporates.\nCO2 is used in photosynthesis to form glucose (the glucose's carbon is from CO2).  Glucose is eventually broken down to form ATP.  Animals store glucose in the form of gylcogen, whereas plants tore it in the form of starch.  Carbon is also present in the atmosphere in the form of other gases (including, I think, greenhouse gases).  It is also present in decaying organic matter, returning to the atmosphere in the form of gas.
