It is a linear body of free flowing water on the surface of the Earth. It is restricted in a stream bed and moves all year round under the force of gravity. Streams are linked by a number of sources. They may originate water from snow melt, run off, precipitation and couple of other streams. They might have tributaries and can also be tributaries to various bodies of water. For instance, small streams might move into big streams and from there on they might move into oceans or lakes.
It is a small stream and can be ephemeral or intermittent, suggesting that they do not consist of water all year round. Creeks are usually shallow and act as tributaries to big bodies of moving water. The North American usage does not mean if a creak should be fresh water or salt water. On the other hand, the British usage of creek means an inlet through the shore.
