What is a triangular area of land where a river deposits mud?

The Mississippi river delta.

A plain is a level area of land. A delta is land created by a river that deposits soil. The term "delta" usually impies the triangular shape of land at the opening of a river into a sea or lake. However a delta can be formed by flooding of large rivers. Just below Memphis, there is some flat land that has deep, fertile top soil that has been created by thousands of years of flooding…

The land formed by deposited soil at the mouth of a river is called a delta (named for the Greek letter, which is similarly triangular in shape).

A river delta.

I am not sure of the answer but it is not a delta since a delta need not be marshy and the question asks about marshy land.

When a river deposits sediment on land, it can cause an alluvial fan. Although more common in arid places, they can also form in humid ones.

There are five nouns. They are piece, land, mouth, river, and delta.

Alluvial deposits are river/stream deposits, whether they are found at the mouth of the river or anywhere along its length. In some cases, the alluvial deposits at the mouth of a river can form a delta. If this is not what you wanted to know, please rephrase the question. As it stands, this is an incomplete sentence with a question mark at the end of it.

it is called a delta

A river delta.

A floodplain

alluvial fan?

The land built up by alluvial soil is called the delta, after the triangular or fan shape formed by multiple channels depositing silt. Over the centuries, the small triangle at the mouth of the river can extend the land out into a body of water. For a good view of how the land is extended, see the link below to the Ganges River Delta.

A is an area of land where a river enters a lake of sea?

The land formed by deposited soil at the mouth of a river is called a delta (named for the Greek letter, which is similarly triangular in shape).

Silt deposited at the mouth of a river forms a 'delta' - so named because of the triangular shape of the silt formation resembling the triangular shape of the Greek letter delta

An area of land that drains to one river (or a river and its tributaries) is a drainage basin or watershed.

The land formed by silt deposited at the mouth of a river is called a delta (named for the Greek letter, which is similarly triangular in shape).

The Nile River deposits its sediment into the Red Sea. The Nile River delta is rich, fertile land that covers 150-miles of Mediterranean coastline from Alexandria in the west to Port Said in the east.

A river basin is an area of land drained by a river and its tributaries.

River Delta or just simply delta.

The land formed by deposited soil at the mouth of a river is called a delta (named for the Greek letter, which is similarly triangular in shape).

The type of land form that the Nile river formed at its mouth is a delta. This is where you will find most deposits of sediments that are from the river.

Assuming that three lengths indicate the plot of land is triangular, the area is 3550 square feet.

It is an area of land that is drained by a river. It is also a ridge or elevated area of land that divides two areas of land that are drained by two river systems.

This is the 'river catchment'.

This area is commonly known as the Sinai Peninsula.

Area = 16.2 sq metres.

Rivers move slowly at the river mouth. The river carries a lot of sediment and mud. The river deposits (drops) its sediment and mud at its mouth. This sediment and mud spreads out into a fan- like shape, or delta, across the mouth of the river. If the force of the sea tides and water is not very strong, the mud deposits cannot be washed away. Instead, the deposits break up the flow of the…

Its called a river basin

The area of land drained by a river is called a "catchment area". It is so-called because is the the area that catches the precipitation (rainfall). Another term is "river basin", but this is less specific. (The geographical term, "catchment area", is often used to describe the area served by, say, a school or hospital).

The land formed by deposited soil at the mouth of a river is called a delta (named for the Greek letter, which is similarly triangular in shape).

The floodplain is an area of flat land found on either side of a river that usually becomes wider as the river nears its mouth. A low watery formation of land at the mouth of a river is called a delta.

The area around the Nile River is extremely fertile and perfect for farming. Each year when the Nile floods, the water deposits silt onto the land. Silt is similar to a fertilizer and helps plants grow.

Drainage basin.

A previous answer from Arrivisto: The area of land drained by a river is called a "catchment area". It is so-called because is the the area that catches the precipitation (rainfall). Another term is "river basin", but this is less specific. (The geographical term, "catchment area", is often used to describe the area served by, say, a school or hospital).

The land formed by deposited soil at the mouth of a river is called a delta (named for the Greek letter, which is similarly triangular in shape). The most well known are the Ganges River Delta, India, the Nile River Delta, Egypt, and the largest is the Amazon River Delta, Brazil.

It does flood. They are not afraid because it deposits silt over the land, which makes plants grow faster.

Land drained by a river is a watershed. This is an area of land that feeds all the water running under it and draining off of it into a body of water.

its an area of land that a river runs through and the part that the river floods every day. :)

The drainage basin is all the land that is drained by a river.

A water catchment area.

Watershed, and Area is spelled AREA not AERA :)

Yes, you can pan for gold in the Carson River, but it is not currently considered a likely area to find placer gold. The Comstock Lode area downstream from Carson City through Dayton was mined thoroughly in the late 1800's and there is little accessible gold remaining. Most of the river there is privately owned but some BLM land is near Dayton and the Fort Churchill Road. Only a couple of miles of poorly-accessible public…

Flood plains.

Because it is the land area that supplies water to a river system :)

No not every river IS a catchement. Although, yes every river does have a catchment area. The catchment area is the surrounding land within a watershed in which a single river system drains.

that is what is called a basin
