Transcript of Rivers and Streams

Rivers and Streams Rivers and streams can be found anywhere, often starting from springs, snowmelts, or lakes. The water is clearer, cooler, and has higher oxygen levels at the source of the river or stream than at the mouth of it. ~Carolyn Corson Biome of: Towards the center of the river or stream, it can widen out or the depth could increase. The water will pick up sediment along the way, so near the mouth of the river or stream, the water becomes murky. Near the mouth, there is a decresae of oxygen levels because less light penetrates the water because of all the sediment, so fish like carp and catfish, who require less oxygen, can be found near there. In the Freshwater Ecosystem. Everyone comes in contact with a river or stream in their life. From outer space, the earth looks like it has veins of water flowing all over it. Actually, though there are many rivers and streams, they actually only account for only .3% of the earths total surface. They run everywhere across the surface of this planet, and a few even flow north, like the Nile river in Egypt. Some start at mountains even, and some join with others, called tributaries. Salmon and trout are some kinds of fish that can stand the colder water near the source of the waterway. Often in the spring, rivers and streams overflow and flood their banks, especially farther down the waterways. Rivers like the Colorado River have carved out the landscape leaving a deep print on the earth. Water spouts happen when the conditions for tornado happen over water. This means that a water spout can happen over a river or stream. When high layers of cool air run across warm water, with moist air rising up, a water spout is formed. The tunnels of water suck up water as they go until they die. Sediment is deposited when the river or stream doesn't have the energy to carry it anymore. Waterfalls need two things: Ample rainfall and
an elevated area. Often, water trickles down the mountain until it rushes over an edge- a waterfall. The rivers and stream often work with their surroundings to have a peaceful area, but sometimes things go wrong. Video! The climate of the river or stream depends on where you are. If you are in the north or somewhere cold, the water will be colder. There is also a lot of rain around the waterways, especially in the spring, which is why it often floods. Sometimes trees of debris get logged in the river or stream, and sometimes beavers build dams on a river. More plants, algae, and fish can be found near the middle of the river or stream, too. Some aquatic plants that live in a river or stream are algae, mosses, and some submerged plants with leaves. Some plants that live beside the river or stream include wild flowers and grasses, or small trees. The type of soil can be a clay sort of compilation, or is can be dirty or rocky. The terrain also depends on where you are. Often, a river or stream is surrounded by wildlife of plants and animals. Some animals that live off or near the river or stream include frogs, salamanders, fish like salmon and trout, wildlife animals like bears, raccoons, beavers, and even mountain lions, and winged animals like bats, herons, and hawks. Because animals use the river or stream for a water source, there aren't any changes of behavior of physical adaptations. Animals need this Biome to survive. Rivers and streams move in one direction. They often take twists and turns throughout their journeys to a larger body of water. http://www.videopediaworld.com/video/31595/River-Biomes-Plant-Life-in-the-River-Water Copy this link to watch a short video about plant life in the rivers and streams. When rivers flood, it can throw off the balance of the surrounding area. When a river or stream becomes clogged full of algae, or debris, it can cause problems. If animals are being over-hunted, that too can throw off the natural balance of the biome. To use Prezi: If you cannot read everything in a box or a picture is blury, you can use your mouse scroller to scroll backwards. If you need to move over slightly, you can click on the screen and drag to where you want to go. A symbiotic relationship of the biome would be something like the fish that depend on the algae and the water. Or Other animals that depend on the water to survive.
