EROSION AND SEDIMENT TRANSPORT
EXAM QUESTIONS AND 100% VERIFIED
ANSWERS!!
What is denudation?
The long-term sum of processes that cause the wearing away of the Earth's surface by water,
wind, and ice.
What is weathering?
The process of breaking down rocks and minerals on the Earth's surface.
What is transport?
The movement of eroded materials by water, wind, or ice.
What are sediment fluxes?
The transfer of sediment from one location to another.
How does human impact affect sediment fluxes?
Human activities can alter the natural sediment fluxes, leading to changes in erosion and
deposition patterns.
What is degradation?
The process of land surface being worn down and lowered.
What is levelling of land surface?
The process of making the land surface more even and flat.
What is potential energy?
The energy possessed by an object due to its position or condition.
What is mass wasting?
The downhill movement of rock, soil, and debris under the influence of gravity.
, What are the three main stages of river development?
Youthful, mature, and old-age stages.
What are the distinct landforms associated with each stage of river development?
Each stage has its own set of landforms that occur along the length of a river's course.
What is the cycle of erosion?
A model that describes how rivers erode uplifted land to base level.
What is Davisian geomorphology?
The landscape evolution theories proposed by Davis, which were criticized by later
geomorphologists.
What did Ruddiman and Raymo suggest in 1992?
They suggested that Tibetan Plateau uplift and increased rates of chemical weathering led to
global climatic cooling and the onset of northern hemisphere glaciation.
What happens during degradation and levelling of land surface?
High ground is weathered and degrades into a flat land surface.
What are young orogens?
Uneven surfaces of land, such as the Himalayas.
What are old orogens?
Land surfaces where erosion has begun to level the surface, such as the Brecon Beacons.
What are stable cratons?
Land surfaces where erosion has completely leveled the surface, such as Western Australia.
What is chemical weathering?
The process of rock breakdown through chemical reactions.
What does chemical weathering generally require?
