What is the name for the end of a river?

deltaThe end of a river is its mouth, or delta. At a river’s delta, the land flattens out and the water loses speed, spreading into a fan shape. Usually this happens when the river meets an ocean, lake, or wetland.

What is another name for a river mouth?

delta; estuary; river-mouth.

How can you tell the age of a river?

Scientists look at various geologic clues to help determine the age of a river, including how old the valley surrounding it is, how deep the water cuts into the riverbed, and the age of the sediments carried by the river.

What are parts of a river called?

Banks are the sides of a river or stream between which the water normally flows. The bed (also called the river bed) is the bottom of the river (or other body of water). Beackish water is water that is saltier than river water but less salty than sea water.

What are the main characteristics of a river in its old stage?

Old Stage – Rivers. At the old stage of the river it is flowing on flat land. As a result it has to use most of its energy to flow instead of moving its load. More deposition starts to occur and common features begin to form such as ox bow lakes (diagram).

What type of feature would you see in a mature river?

Mature River: The landscape over which it passes is steep enough that the river’s slope enables a velocity capable of moving not only the finer sediments, but also the larger pebbles and cobbles by way of rolling, bouncing and saltation along the river bed.

What are three characteristics of an old river?

Ridges are sharp, valleys are steep sided, and the landscape has maximum relief. Old age. The valley walls wear down, the river creates a broad flood plain, and begins to meander, or develop wide bends.

Where are rivers found?

The source of a river is usually found in high places such as hills or mountains. A river can have more than one source. Some rivers begin where a natural spring releases water from underground. The source of the River Thames is a spring.

What are two types of rivers?

ClassificationYouthful river: A river with a steep gradient that has very few tributaries and flows quickly. … Mature river: A river with a gradient that is less steep than those of youthful rivers and flows more slowly. … Old river: A river with a low gradient and low erosive energy.More items…

How do rivers begin?

Most rivers begin life as a tiny stream running down a mountain slope. They are fed by melting snow and ice, or by rainwater running off the land. The water follows cracks and folds in the land as it flows downhill. Small streams meet and join together, growing larger and larger until the flow can be called a river.

Where do rivers usually end?

Rivers eventually end up flowing into the oceans. If water flows to a place that is surrounded by higher land on all sides, a lake will form. If people have built a dam to hinder a river’s flow, the lake that forms is a reservoir.

What is a river bank called?

In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. … Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them.
