100
Streams feed into larger streams
Tributary?
100
when river lets off its load
deposition
100
This another name for the final stage of a river.
lower course of the river
100
The action of deposition comes when the river speed is slow that cuts off the neck of the meander and results in this landform.
ox bow lakes
100
The term “traction” refers to the way in which materials in the river’s load are bounced along the riverbed. (true or false)
False
200
The area drained by the river and its tributary
drainage basin
200
larger stones rolling along river beds
traction
200
Sections of the river where the water flows quickly and turbulently over a shallow region of the river, leaving rocks as steep outcrops in the upper stage of the river.
rapids
200
this course of the river has the steepest gradient
upper course
200
Natural embankments created alongside a river are known as:
levees
300
River patterns flowing from a central high point to a flattened area.
radial drainage
300
this river process mainly occur in the upper course of the river
erosion
300
waterfall
300
These two main factors affect the speed of the river.
slope gradient and the roughness of the channel
300
This drainage pattern occurs when tributaries join the main river at right angles.
trellis
400
where the river begins
source
400
the power of water eroding river banks
hydraulic action
400
this is form after a waterfall is fully eroded
gorge
400
the speed at which water moves through its channel is known as
velocity of the river
400
a river branch flowing AWAY from the main stream.
distributaries
500
where tributary and main steam meets
confluence
500
Water soluble minerals in the rocks react chemically with the river water and dissolve.
solution
500
Bends in the river at the middle stage are punctuated by these landforms on the concave and convex banks of the river.
river cliffs and slip off slopes
500
Erosion and speed have a direct relationship means that.
speed increases erosion increases as well
500
This drainage pattern resembles a tree.
