Rivers and streams are bodies of water that flow across the surface of the Earth, typically in a channel or bed. Rivers and streams are an important part of the Earth’s water cycle, as they collect and transport water from higher elevations to lower elevations.
Rivers and streams can vary in size and flow rate, ranging from small streams that flow only during certain times of the year to large rivers that flow all year round. They can also vary in terms of their geology, with some rivers and streams flowing through rocky, mountainous terrain and others flowing through flat, low-lying areas.
Rivers and streams are important sources of water for a variety of purposes, including irrigation, drinking water, and industrial use. They are also important habitats for a variety of plants and animals, and are often used for recreation, such as fishing and boating.

Difference River and Stream
The main difference between rivers and streams is the size and flow rate of the water body. Rivers are generally larger and have a higher flow rate than streams.
Rivers are typically defined as larger, permanent bodies of water that flow through a channel or bed from one area to another. They are usually fed by tributaries, which are smaller streams that flow into the main river. Rivers typically have a larger watershed, which is the area of land that drains into the river.
Streams, on the other hand, are smaller bodies of water that flow through a channel or bed from one area to another. They are typically fed by smaller tributaries and have a smaller watershed than rivers. Streams can vary in size and flow rate, and may only flow during certain times of the year, depending on the climate and geology of the region.
In general, rivers are more important sources of water for human use and are often used for irrigation, drinking water, and industrial purposes. Streams, on the other hand, are typically used for recreational purposes, such as fishing and boating, and are important habitats for a variety of plants and animals.
What are deltas and alluvial fans?
A delta is a landform that is created when a river or stream flows into a larger body of water, such as an ocean, lake, or another river. Deltas are typically triangular in shape and are formed by the accumulation of sediment carried by the river or stream.
As the river or stream flows into the larger body of water, the velocity of the water slows down, causing the sediment it is carrying to be deposited in the water. Over time, this sediment builds up, creating a delta. Deltas are typically found at the mouth of a river or stream, where the water flows into a larger body of water.
An alluvial fan is a landform that is created when a stream or river flows onto a flat plain or into a valley, depositing sediment as it flows. Alluvial fans are typically formed in areas where the terrain changes suddenly, such as at the base of a mountain or hill. The sediment is deposited in a fan-shaped pattern, with the sediment at the base of the fan being the coarsest and the sediment at the top of the fan being the finest. Alluvial fans are typically found in arid or semi-arid regions, where there is not enough vegetation to absorb the water and sediment carried by the stream or river.
What are the five largest rivers, based on discharge?
The five largest rivers in the world, based on discharge, are:
- The Amazon River: The Amazon River is the largest river in the world in terms of discharge, with an average flow of about 209,000 cubic meters per second. It is located in South America and flows through Brazil, Peru, and Colombia.
- The Congo River: The Congo River is the second largest river in the world in terms of discharge, with an average flow of about 41,000 cubic meters per second. It is located in Africa and flows through the Democratic Republic of the Congo, Angola, and the Republic of the Congo.
- The Yangtze River: The Yangtze River is the third largest river in the world in terms of discharge, with an average flow of about 30,000 cubic meters per second. It is located in China and is the longest river in Asia.
- The Mississippi-Missouri River: The Mississippi-Missouri River is the fourth largest river in the world in terms of discharge, with an average flow of about 17,000 cubic meters per second. It is located in the United States and flows through 10 states, including Illinois, Missouri, and Louisiana.
- The Niger River: The Niger River is the fifth largest river in the world in terms of discharge, with an average flow of about 16,000 cubic meters per second. It is located in West Africa and flows through a number of countries, including Guinea, Mali, and Niger.
