Every river has processes of transportation, which are
solution, suspension, corrasion and saltation
solution, suspension, saltation and attrition
solution, suspension, saltation and traction
solution, hydraulici action, corrasion and traction
The material that a river carries is called
load
mouth
stones
river bed
Read the definition and identify it: "The process of transportation in which the lightest particles of soil and sand that make the river look cloudy as are carried along, is called .."
solution
suspension
saltation
traction
You have "traction" when
the transported minerals are dissolved in the water
smaller particles such as stoned bounce along the river bed
the heaviest particles - large stones and rocks - roll along the river bed
the lightest particles of soil and sand are carried along the river course
What are the four main processes of erosion?
Hydraulic action, abrasion, attrition and solution
Hydraulic action, corrasion, saltation and solution
Hydraulic action, abrasion, attrition and saltation
Ask Ms Daminato, I can't be bothered!
Hydraulic action is when
sand and stones rub against the bank and bed and knock off other particles
the force of the water knocks particles off the banks and the river bed
boulder and large stones carried by the river collide with each other and break into smaller pieces
when acids in the river dissolve the rocks that make up the bank and bed
Deposition usually occurs …
in the upper course
in the lower course
in the middle course
everywhere, stop bluffing!
Interception is when
the rainfall leaks into the soil and creates groundwater
the rainfall falls on leaves and trees and does not reach the soil
rainfall evaporates due to the sun energy
raifall flow over land moved due to the grativty
The bigger the gravity
the slower the river flows
the higher the evaporation
the faster the river flows
the louder mr Imbò laughs
In the upper cours of a river the channel is
shallow
flat
steep
has meanders
In the upper course the water is
turbulent
clear
deep
slow moving
What are the main characteristics of the upper course
steep gradient, v-shaped vallery, vertical erosion and meanders
steep gradient, v-shaped valley, vertical erosion, waterfalls and rapids
V-shaped valley, meanders, waterfalls and gentle gradient
steep gradient, v-shaped vallery, vertical erosion, waterfalls and deltas
