What is brook definition?

A brook is a small, shallow stream, usually a tributary or a smaller branch of a larger river or stream. It is characterized by its clear, cold, and fast-flowing water, with a rocky or sandy bed and banks. Brooks are often found in wooded areas or rural landscapes, where they provide a habitat for a variety of aquatic plants and animals, such as trout, crayfish, and frogs. The size of a brook may vary from a few inches wide to several feet wide, and its flow rate may also vary depending on the season and the amount of rainfall. Brooks are important components of healthy ecosystems and are often used for recreational activities such as fishing, hiking, and picnics.
