Parts of a River
The point where the river ends.
What is the mouth
Pebbles, gravel and silt eroding a river's sides and bottom by scraping and grinding against them.
What is abrasion
When the river floods and material is deposited on the river bank. The heaviest material is deposited first creating a natural embankment.
What is levee.
From the source to the mouth we see the gradient change (increase or decrease)
What is decrease
The point where two rivers meet.
What is a confluence
When floating mud, silt and sand particles are transported within a river.
What is suspension.
When a river deposits it material at the mouth of a river, the river makes its way through the sediment by splitting into distributaries.
What is a delta.
Which section of the river profile is vertical erosion prominent.
What is the upper course
The boundary separating one drainage basin from another
What is the watershed
When small stones, pebbles and silt bounces along the river bed.
What is suspension.
On the outside bank of a river there are fast currents eroding and undercutting the bank creating feature.
What is river cliff.
In the middle course we notice there is no longer vertical erosion. The channel is now becoming wider. This is because of .....
What is lateral erosion.
The land drained by a river and its tributaries.
What is a drainage basin.
Material carried by the river collide with each other cause them to erode becoming smoother and rounder.
What is attrition.
In a waterfall the overhang usually falls into the plunge pool. It is eroded through the process .........
What is abrasion
Finer material is being transported here and eventually deposited.
What is the lower course
A small stream leaving a main river.
What is a distributary.
Large boulders are rolled along the river bed.
What is attrition.
The plunge pool is created by the force of the water itself. This process is known as
What is Hydraulic action
This increases along the river profile because of tributaries and surface runoff.
What is volume
