how was the nile delta formed

Several scarps (cliffs) are visible at image lower left. My house during my life Wiki is a FANDOM Lifestyle Community. A Gilbert delta is formed when the sediments deposited to form the delta are coarse in nature. have plants that grow in abundance. Topsoil in the delta can be as much as 70 feet (21 m) in depth. When a river channel encounters another body of water, it loses it speed and deposits such sediments onto a flat area. The ancient pharaohs (kings) and queens of Egypt established several royal cemeteries, along the Nile River valley. The Nile's deep, navigable waters flow northward into Lower Egypt, where at Cairo the Nile becomes a wide, marshy delta. From north-to-south, the delta is approximately 160 km in length. A fast and turbulent river transports larger sediments in size and amount. The Nile Delta The Delta is formed by the division of the branches of the River Nile as it flows south through the Valley formed by the Nile in Upper Egypt. Take your favorite fandoms with you and never miss a beat. With cooler temperatures and some rain, the Nile Delta region becomes quite humid during the winter months. delta [from triangular shape of the Nile delta, like the Greek letter delta], a deposit of clay, silt, and sand formed at the mouth of a river where the stream loses velocity and drops part of its sediment load.No delta is formed if the coast is sinking or if there is an ocean or tidal current strong enough to prevent sediment deposition. The sediment deposited by this running water is called Alluvium. The Nile Delta is the delta formed in Northern Egypt (Lower Egypt) where the Nile River spreads out and drains. With a rich and diverse cultural history, the Nile Delta is one of northern Africa's most fertile regions -- people have farmed it for thousands of years. It is the delta formed in Northern Egypt (Lower Egypt) where the Nile River spreads out and drains into the Mediterranean Sea and it is one of the world's largest river deltas. Fish found in the delta include the Striped mullet and soles. It builds up in layers forming a delta. The Nile’s broad fan-shaped Delta is flat and green. Flight down the delta of the Nile to Alexandria. Meaning of nile delta. The lagoon is partly enclosed by two long narrow barrier spits that are surmounted by beach ridges and crossed by tidal entrances of variable position and size. As the polar ice caps melt, much of the northern delta, including the ancient port city of Alexandria, will disappear under the Mediterranean. Potential traps are predominantly formed in relation to these seals with deep-seated faults providing migration pathways. The battle between the river’s flow and the amount of sediments it carries, and the strength of the tidal waves of the body of water, determines the delta’s shape. As the river channel flows over the ground and makes contact with soil, it carries with it sediments like gravel, sand, silt and clay. We know that the Nile delta gave its shape to the Greek letter Δ, but the Nile is not the only river in the world that has such an elegant delta. The Nile Delta at night as seen from the International Space Station in October 2010. Such deltas usually form at places where a mountain river joins a freshwater lake. On the western riverbank, these necropoli (cities of the dead) were built on a gravelly desert plateau formed of limestone and clay overlooking the river. The Nile Deltas are a rock 'n' roll band on their own terms, an unashamed 'song' band with a voice up front drenched in soul. Herodotus, a Greek historian, first used the term "delta" for the Nile River in Egypt. The Delta has a hot desert climate as the rest of Egypt, but its northernmost part, as is the case with the rest of the northern coast of Egypt which is the wettest region in the country, has relatively moderate temperatures, with highs usually not surpassing 31 °C (88 °F) in the summer. This kind of delta is a lot more solid and mimics the shape of a triangle. A typical example of a wave-dominated delta is the Nile Delta in Egypt. Science Fair Project Ideas for Kids, Middle & High School Students. The cuspate deltas are formed where sediments are deposited onto a straight shoreline with strong waves. Relatively coarse sediments are formed in this type of delta. Heavy spring floodwaters from throughout central Egypt inundate the river with sediment every year, and over millennia these sediments were deposited along the river banks to create the fertile river valley. At its farthest reaches, Alexander the Great built Alexandria, a bustling port city and home to the Library of Alexandria and the famed Pharos Lighthouse, one of the Seven Wonders of the Ancient World. Furthermore, Egypt’s Mediterranean coastline is being swallowed up by the sea because of global warming and the rise of the sea level, and the lack sediments being deposited since the construction of the Aswan Dam, in some places as much as 100 yards a year. The Nile Delta is turning into a salty wasteland by rising sea waters, forcing some farmers off their lands and others to import sand in a desperate bid to turn back the tide. Delta of the Nile. A delta can only form when river channels carry sediments into another body of water. The formation of a river delta is a slow process. These sediments pile up into several layers called beds. The three main types of deltas are the arcuate, the bird's foot and the cuspate. The Mississippi Delta is the largest river delta in North America, covering an estimated area of from 10,000 to 13,000 square miles of land according to various sources. The wider portion of the fan is facing the water. To the north-west are three other coastal lakes or lagoons: Lake Burullus, Lake Idku and Lake Maryut. Unlike other landforms affected by water current, a delta is not mainly created because of erosion of land surface caused by the force of wind and water. The bird’s foot delta got its name because it forms like a bird foot’s claw. The outer edges of the delta are eroding, and some coastal lagoons have seen increasing salinity levels as their connection to the Mediterranean Sea increases. It spreads out because it is slowing down and doesn't dig so deep into the earth. In the Nile Delta for example, the Egyptians constructed their towns and cemeteries on turtlebacks; natural highpoints in the landscape that became islands during the inundation. Other animals found in the delta include frogs, turtles, tortoises, mongooses, and the Nile monitor. A new study finds evidence for a theory that suggests the Nile River may have emerged around 30 million years ago, driven by the motion of Earth’s mantle. Nile crocodiles and hippopotamus, two animals which were widespread in the delta during antiquity, are no longer found there. The name Nile is derived from the Greek Neilos (Latin: Nilus), which probably originated … Some rivers drop so much sediment that waves and tides can't carry it all away. What does nile delta mean?
