Geomorphic Flashcards
The physical processes which create and modify landforms on the surface of the earth.
Geomorphic Process
Processes that happens beneath the surface of the Earth
Endogenous
Processes that happens on the surface of the Earth
Exogenous
Degradation Processes
- Weathering
- Mass Weathering
- Erosion and Transportation
Aggradation Processes
Deposition - fluvial, glacial, coastals
Is disintegration and decomposition of rocks in situ - no transportation involved
Weathering
product of weathering; small parts of the parent rock; no organic matte mixed into parent rock
Regolith
Types of weathering
- Physical or Mechanical
- Chemical
- Biological
Disintegration or decay of rocks via weather elements: high temperatures, extreme cold
and freeze-thaw cycles
Physical/Mechanical Weathering
Wet condition and very slow speed
Solifuction
Wet condition and very fast speed
Mudflow
Dry condition and very fast speed
Rockfall
Involves the upward movement of Earth’s mostly solid mantle
Decompression
Magma can also be created when hot, liquid rock intrudes into Earth’s cold crust
Transfer of heat
Occurs when water or carbon dioxide are added to rock
Flux melting
The formation of intrusive igneous rock by solidification of magma beneath the earth’s
surface
Plutonism
Any of various processes and phenomena associated with the surficial discharge of
molten rock, pyroclastic fragments, or hot water and steam
Volcanism
