EROSION, SEDIMENT TRANSPORT
PROCESSES AND IMPACTS EXAM
QUESTIONS AND 100% VERIFIED
ANSWERS!!
What has been recognized by our ancestors regarding soil erosion?
The problem of soil erosion.
What are some methods developed to cope with soil erosion?
Methods and practices for erosion control, including new technologies for better erosion control
structures.
What modern pressures contribute to soil erosion?
Modern agricultural technology, population growth, and economic pressures.
How do modern farming practices contribute to soil erosion?
By introducing new crops, cultivating steep slopes unfit for farming, and using modern
fertilization techniques.
What are the consequences of excessive soil erosion?
It endangers soil fertility, increases reliance on chemical fertilizers, and pollutes streams and
rivers.
How does soil erosion affect reservoirs and ponds?
It reduces their storage capacities and water quality.
What ecosystems are threatened by soil erosion?
Aquatic ecosystems such as lakes, mangroves, and marshes.
What is required to understand the processes of terrestrial ecosystems?
Engineering, hydrologic, and ecological validation.
What are the two major types of soil erosion?
, Geological erosion (natural) and accelerated erosion (abnormal due to human activities).
What characterizes accelerated erosion?
It occurs at a much faster rate than soil can be formed, leading to land degradation.
What forces are involved in soil erosion?
Attacking forces and resisting forces.
What are the two interactive processes in soil erosion?
Detachment of soil particles from the surface and transport of detached particles.
What is necessary for considerable soil loss to occur?
Both detachment and transport processes must be at work.
What are the erosive agents for erosion by water?
Rainfall and runoff.
What are the four interactive erosion sub-processes identified by Ellison?
1. Detachment by rainfall 2. Transport by rainfall 3. Detachment (scour) by runoff 4. Transport
by runoff.
What is the impact of raindrop on soil erosion?
Soil erosion over a land surface is the product of raindrop impact and overland flow.
What is the effect of human activity on soil erosion?
It leads to accelerated erosion, which is destructive and causes land degradation.
What happens to surface soil during accelerated erosion?
It is removed at a much faster rate than it can be built up by soil-forming processes.
Why is only accelerated erosion considered in conservation activities?
Because it has significant destructive impacts on land and soil health.
How does soil detachment occur?
