what is the difference between saltwater and freshwater wetlands?
542858
Quick answer...one has a high salt content and the other does not.  Longer answer...when looking at salt and freshwater, it depends on the content of salt in the water.  Saltwater wetlands are usually along a sea or ocean, or along a tributary leading to them.  The salt content from teh ocean seeps up the river and hits the wetlands.  Freshwater wetlands are unsalanized and contain little or no salt.  This water supports freshwater fish and is a great watering spot for mammels and animals who need fresh (not ocean) water.

The freshwater biome consists of freshwater lakes, ponds, streams, springs, and rivers. These are found all over the world. Many are beautifully landscaped, but some are just downright ugly! Most all bodies of freshwater are enclosed by land, but some rivers and streams empty into the oceans at places called estuaries. Lakes and ponds are divided into three zones. The littoral zone is near the shore where plants and animals are abundant. The next zone is the limnetic zone, which is the open water next to shore, where plankton dominate the water. The last zone is the deep part of the lake/pond called the profundal zone. This is where organisms called heterotrophs, which eat dead organisms that float down from the surface. Temperatures vary in summer from 22*C – 4*C and in winter from 4*C – 0*C. In the spring and fall, the top and bottom layers mix and then the average temperature is 4*C. Streams and rivers are bodies of moving water flowing in one direction. They can be found anywhere, but their exact origin is not really known. They may start out as lakes, ponds, springs, or even melted snow. The characteristics change from the source to the mouth. The source is cooler than the mouth. The water is clearer than of lakes and ponds, and has higher oxygen levels. Freshwater animals such as trout, snails, crabs, and clams along with heterotrophs roam the waters. In the middle part of the stream/river, the width increases, it is less shaded, and more organisms including green plants and algae are found here. Towards the mouth, the water becomes murky and light can penetrate only so far. Fish that don’t loss as much oxygen as other fish, such as catfish and carp, live here. The freshwater biome is home to many beautiful and interesting fauna and flora.

wetlands already ARE a part of the environment! they are not something artificial that you need to blend in...

Did you ever wonder why the oceans are filled with salt water instead of fresh? Just where did the salt come from? And is it the same salt you find on a dining room table? Most of the salt in the oceans came from land. Over millions of years, rain, rivers, and streams have washed over rocks containing the compound sodium chloride (NaCl), and carried it into the sea. You may know sodium chloride by its common name: table salt! Some of the salt in the oceans comes from undersea volcanoes and hydrothermal vents. When water evaporates from the surface of the ocean, the salt is left behind. After millions of years, the oceans have developed a noticeably salty taste.\n\nDifferent bodies of water have different amounts of salt mixed in, or different salinities. Salinity is expressed by the amount of salt found in 1,000 grams of water. Therefore, if we have 1 gram of salt and 1,000 grams of water, the salinity is 1 part per thousand, or 1 ppt.\n\nThe average ocean salinity is 35 ppt. This number varies between about 32 and 37 ppt. Rainfall, evaporation, river runoff, and ice formation cause the variations. For example, the Black Sea is so diluted by river runoff, its average salinity is only 16 ppt.\n\nFreshwater salinity is usually less than 0.5 ppt. Water between 0.5 ppt and 17 ppt is called brackish. Estuaries (where fresh river water meets salty ocean water) are examples of brackish waters.\n\nMost marine creatures keep the salinity inside their bodies at about the same concentration as the water outside their bodies because water likes a balance. If an animal that usually lives in salt water were placed in fresh water, the fresh water would flow into the animal through its skin. If a fresh water animal found itself in the salty ocean, the water inside of it would rush out. The process by which water flows through a semi-permeable membrane (a material that lets only some things pass through it) such as the animal's skin from an area of high concentration (lots of water, little salt) to an area of low concentration (little water, lots of salt) is called osmosis.\n\nThis is also why humans (and nearly all mammals) cannot drink salt water. When you take in those extra salts, your body will need to expel them as quickly as possible. Your kidneys will try to flush the salts out of your body in urine, and in the process pump out more water than you are taking in. Soon you'll be dehydrated and your cells and organs will not be able to function properly.

Wetlands are essential to maintain the balance of the hydrologic cycle; they offer large surface areas of water and thus regulate the amount of water that flows, evaporates and eventually falls down again as rain. In addition, a wetland such as an estuary is the boundary between the sea and the land; they can buffer the influence of the tides and sea currents, and are usually very productive areas (that is, if pollution does not degrade them).\nEspecifically for the San Francisco area, here´s a link to the site for the San Francisco Bay reserve, they discuss the benefits and problems of the area:\nhttp://nerrs.noaa.gov/SanFrancisco/welcome.html\n\nand the local Wetlands Regional Monitoring Program:\nhttp://www.wrmp.org/\n\nand

A marsh is a wetland containing a diverse abundance of plant species. The biodiversity in the marsh allows waste water to be filtered through the rootsystems and the nutrients absorbed by the plants. Marshes are different from swamps in that they do not contain many woody plants like trees, but rather things like reeds, sedges and grass. These are especially good for filtering water because their root system is not divergent off of one main root, but instead a network of roots that can better spread out through the water.

it does but it's diluted.Some bodies of water have higher salt content than others.

(m)\n\nEveryone who has been to the beach knows that seawater is salty. Everyone also knows that fresh water in rain, rivers, and even ice is not salty. Why are some of Earth’s waters salty and others not? There are two clues that give us the answer. First, “fresh” water is not entirely free of dissolved salt. Even rainwater has traces of substances dissolved in it that were picked up during passage through the atmosphere. Much of this material that “washes out” of the atmosphere today is pollution, but there are also natural substances present.\n\nAs rainwater passes through soil and percolates through rocks, it dissolves some of the minerals, a process called weathering. This is the water we drink, and of course, we cannot taste the salt because its concentration is too low. Eventually, this water with its small load of dissolved minerals or salts reaches a stream and flows into lakes and the ocean. The annual addition of dissolved salts by rivers is only a tiny fraction of the total salt in the ocean. The dissolved salts carried by all the world’s rivers would equal the salt in the ocean in about 200 to 300 million years.\n\nA second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater. Why are these lakes salty while most of the world’s lakes are not? Lakes are temporary storage areas for water. Rivers and streams bring water to the lakes, and other rivers carry water out of lakes. Thus, lakes are really only wide depressions in a river channel that have filled with water. Water flows in one end and out the other. \n\nThe Great Salt Lake, Dead Sea, and other salt lakes have no outlets. All the water that flows into these lakes escapes only by evaporation. When water evaporates, the dissolved salts are left behind. So a few lakes are salty because rivers carried salts to the lakes, the water in the lakes evaporated and the salts were left behind. After years and years of river inflow and evaporation, the salt content of the lake water built up to the present levels. The same process made the seas salty. Rivers carry dissolved salts to the ocean. Water evaporates from the oceans to fall again as rain and to feed the rivers, but the salts remain in the ocean. Because of the huge volume of the oceans, hundreds of millions of years of river input were required for the salt content to build to its present level. \n\nRivers are not the only source of dissolved salts. About twenty years ago, features on the crest of oceanic ridges were discovered that modified our view on how the sea became salty. These features, known as hydrothermal vents, represent places on the ocean floor where sea water that has seeped into the rocks of the oceanic crust, has become hotter, and has dissolved some of the minerals from the crust, now flows back into the ocean. With the hot water comes a large complement of dissolved minerals. Estimates of the amount of hydrothermal fluids now flowing from these vents indicate that the entire volume of the oceans could seep through the oceanic crust in about 10 million years. Thus, this process has a very important effect on salinity. The reactions between seawater and oceanic basalt, the rock of ocean crust, are not one-way, however; some of the dissolved salts react with the rock and are removed from the water.\n\nA final process that provides salts to the oceans is submarine volcanism, the eruption of volcanoes under water. This is similar to the previous process in that seawater is reacting with hot rock and dissolving some of the mineral constituents.\n\nWill the oceans continue to become saltier? Not likely. In fact the sea has had about the same salt content for many hundred of millions if not billions of years. The salt content has reached a steady state. Dissolved salts are being removed from seawater to form new minerals at the bottom of the ocean as fast as rivers and hydrothermal proce

duh !! salt in water = salt water . salt = thirst . thirst = water . go drink some !!

both good and bad,\n\nBillions of gallons of salt water moves inland, all that salt can kill trees.......\n\n\nOn the flip side, it kills thousands of polluting humans......\n\nso I guess it depends on your point of view.

Yes, salt water is a sodium chloride solution with Na+ and Cl- ions. when two seperate condutors are immersed in the solution without contacting each other and a bulb or any electrical appliance is placed across the conductors the positive and negative ions migrate and conducts electricity.

a wetlands is any land that is covered in water or remains wet Thur out the year, id doesn't matter if it in in a hot tropical area or in Alaska

Salt water does not have any specific effect on weather formation. But all sources of water whether it is river, lake, pond, sea or ocean; by evaporation affect humidity and therefore the weather conditions.

Osmotic pressure refers specifically to the difference in the concentration of elements between two solutions.  If you place a semipermeable barrier between the two solutions, water will flow across that barrier until the concentrations are equal.\n\nIn this way, when you put a freshwater plant into salt water, the fresh water flows out from the plant through the cell membranes, which are semipermeable to water but not salt.\n\nThis osmotic pressure is actually how your kidneys work, to filter fresh water from the fluid you drink and leave a more concentrated solution behind.
