Source
The source (i.e. start) of a river is where it originates, e.g. a spring or a lake.
Mouth
The mouth is the end of the river where it meets the sea or a lake.
The Mouth of a river
Long Profile
The Long Profile shows the shape of the rivers course from source to sea
Cross Profile
The Cross Profile is the side view of the river which shows from source to mouth, the altitude of the river.
Erosion
Erosion happens because of decomposition (wearing away) of rocks.
Transportation
Transportation is the movement of sand, silt, sediment, or anything else carried by a river, from one point to another by the river.
Deposition
Deposition is when the river loses energy, and it can't carry as much load. It drops its load (material it has been carrying), starting with the largest particles.
Load
The load is any material transported by the river, e.g. Sand, pebbles, rock particles.
Meander
A Meander is a winding curve in a river.
Weathering
Weathering is the wearing away of rocks. It can be weathering, biological or physical weathering.
Infiltration
Infiltration is the downward movement of water that seeps into the soil or permeable (also called porous) rock at ground level.
Permeable
Permeable materials are materials that water can pass through, e.g. limestone.
Impermeable
Impermeable materials are materials that water cannot pass through, e.g. clay.
Throughflow
The throughflow is the flow of water in the soil sideways, towards the river (sideways movement of water).
Hydrograph
A hydrograph is a graph showing discharge or rainfall.
River discharge
The river discharge is the amount of water that flows through a river.
Velocity
The velocity is the speed and direction of river flow.
Transpiration
Transpiration is the evaporation of water from plants through their leaves.
Groundwater flow
Groundwater flow is when water travels through bedrock.
