Streams

What are Streams?

A stream is a body of water that flows in a channel. It is smaller than a river and can vary in size from a small trickle to a larger, swiftly flowing waterway.

Formation of Streams

Streams are typically formed from the flow of water downhill, often as a result of precipitation such as rain or melting snow. The water accumulates and forms small channels that eventually develop into streams.

Characteristics of Streams

• Flow: Streams can have varying flow rates, from slow-moving to fast-flowing depending on factors such as slope and volume of water.
• Channels: Streams flow within channels, which can be narrow or wide, and can change over time due to erosion.
• Bank: The sides of the stream are called banks, and they can also be eroded over time.
• Meanders: Some streams develop curves or bends known as meanders as they flow.
• Deposition: Streams can also deposit sediment and form features such as sandbars and deltas.

Importance of Streams

Streams are vital to ecosystems as they provide water for plants and animals. They also play a role in erosion, transportation of sediment, and shaping the landscape.
