What is Water Cycle? It is the flow/movement and storage of water in and between the atmosphere, the lithosphere, the hydrosphere & the biosphere It also involves the changes in the state of water - in gaseous, solid & liquid state
River Basin & Fluvial Processes A river forms when rain falls on the land which forms rills rills flow downslope, more rainfall, in the form of runoff, joins them, and the rills grow larger, the rills are large enough to be called streams
River Basin A main stream and its tributaries river forms a network of streams, called a drainage network/system This network occupies and drains a definite area of land. This area is called a drainage basin
River Basin The boundary of the basin forms the watershed of the basin. It follows the crests of the ridges & hills.
