What sort of erosion is the river doing in
the upper course (closest to the source
where it is flowing through hills and
mountains)?
vertical (downwards) erosion
lateral (sideways) erosion
Where does lateral erosion take place?
in the upper course (closest to the source
where it is flowing through hills and mountains)
at the source
in the middle and lower course (further away
from the source, closer to the mouth)
What type of rock does the river find the
easiest to erode?
more resistant (harder rock)
less resistant (softer) rock
What are interlocking spurs?
sections of rock that stick out, that the river has
not been able to erode as easily
sections of rock that stick out, that the river has
been able to erode easily

Apart from farming, why else is the Volga
River important to people?
it is important because it looks beautiful
it is important for the fishing industry
it is important for producing wheat and barley
What erosion process is similar to
sandpapering?
attrition (rocks collide and break up)
abrasion (rocks wear away each other and the
riverbed and the banks)
hydraulic action (the force of the water breaks
solution (acids in the water dissolve the rock)
What erosion process can be thought of
as 'water power'?
attrition (rocks collide and break up)
abrasion (rocks wear away each other and the
riverbed and the banks)
hydraulic action (the force of the water breaks
down the riverbed and banks)
solution (acids in the water dissolve the rock)
Deposition means...
drop off
carry
Deposition happens on the...
inside of a river bend where the river moves
more slowly
outside of a river bend where the river moves
the fastest
What is flooding?
The continuous recycling of water on Earth.
When a river erodes the banks (sides).
When a river's water spills over its banks (sides)
and spreads out over the surrounding area.
13: Floods are only caused due to physical
causes, such as heavy rainfall. True or false?
True
False
14: Why does urbanisation (the building and
extension of towns and cities) increase the
risk of flooding?
O because towns and cities are busier
O towns and cities have impermeable surfaces
that don't allow the water to go through it
O towns and cities have permeable surfaces that
do allow the water to go through it
because towns and cities are busier
towns and cities have impermeable surfaces
that don't allow the water to go through it
towns and cities have permeable surfaces that
do allow the water to go through it
15: What is a dam?
A dam allows the free flow of water.
A dam is a barrier that stops or restricts the
