It is caused by virus that only infects people who already have hepatitis B. The delta hepatitis virus (also known as hepatitis D or HDV) is an RNA virus, meaning that its genetic material is made up of ribonucleic acid.
Answers. Best Answer: A delta is formed when a high flow water body meets a low flow one. Meaning, when a river meets a lake or ocean. The river carries sediment because of it's high energy (flow). When it suddenly slows down the sediment drops out all at once and a delta form A river creates a delta by laying down sediment or rock debris such as gravel, sand, silt, and clay that it has picked up and carried along its course. Alluvium (pronounced ah-LOO-vee-em) is the general term for sediment deposited by running water. Arcuate deltas are the commonest form of delta. They are fan-shaped, with the wide portion of the fan farthest from the mainland. Crossed by many short, well-defined distributaries, these types of deltas are composed of relatively coarse sediments. Answered by The Community. Making the world better, one answer at a time. A delta is an area where a river enters a larger body of water. Weathered particles are eroded and then deposited when the momentum of the river slows down. So a delta has to start with weathered particles and then the particles have to be eroded and then they are deposited A delta is often a patchwork of marshes, swamps, lakes, and tidal flats (muddy or marshy areas that are covered and uncovered by the rising and falling tides). During the normal flow of the main river in a delta, all the water is guided out to the ocean by the active distributaries. Arcuate deltas are the commonest form of delta. They are fan-shaped, with the wide portion of the fan farthest from the mainland. Crossed by many short, well-defined distributaries, these types of deltas are composed of relatively coarse sediments. A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot transport away the supplied sediment. Despite a popular legend, this use of the word delta was not coined by Herodotus. The delta of the St. Clair River between the Canadian province of Ontario and the U.S. state of Michigan is the largest delta emptying into a body of fresh water. Delta hepatitis is caused by a virus that only infects people who already have hepatitis B. The delta hepatitis virus (also known as hepatitis D or HDV) is an RNA virus, meaning that its genetic material is made up of ribonucleic acid. People who already have chronic hepatitis B can acquire delta hepatitis, as well. This often causes severe inflammation of the liver, and the viruses are less likely to be cleared. Delta hepatitis makes chronic hepatitis B much worse. Erosion is also an important control in tide dominated deltas, such as the Ganges Delta, which may be mainly submarine, with prominent sand bars and ridges. This tends to produce a dendritic structure. Tidal deltas behave differently from river-and wave-dominated deltas, which tend to have a few main distributaries. The delta of the St. Clair River between the Canadian province of Ontario and the U.S. state of Michigan is the largest delta emptying into a body of fresh water. It is a landform that is created at the mouth of a river where that river flows into an ocean, sea, estuary, lake, reservoir or another river. Deltas are formed from the depos … ition of the sediment carried by the river as the flow leaves the mouth of the river. 60 people found this useful. A river delta is the landform occurring at the river mouth, where the river meets the sea. It is largely a result of the silt brought down by the river system. The river sprea … ds out in a fan shape into many channels called distributaries, which form outlets and islands
