A Study about Geomorphological Landforms And Geomorphic Features Produced by the Landforms
[attachment=42426]
An Introduction to-
The following maps are represents the same area on Earth’s surface and showing three different view of landforms.
1. Represents the topographic elevation map.
3. the image on the right is the geologic interpretation of surface sediments and geomorphology.
GEMORPHOLOGY
Geomorphology is the process-based study of landforms.
Geo-morph-ology originates from Greek: Geo meaning the “Earth”, morph meaning its “shape”, and ology refers to “the study of”.
Geomorphology defines the processes and conditions that influence landform development, and the physical, morphological, and structural characteristics of landforms.
Faulting
Normal: rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall.
Reverse: rocks above the hanging wall moves up relative to the footwall
Strike: rocks on either side of a nearly vertical fault plane move horizontally
Oblique: normal or reverse faults have some strike-slip movement, or when strike-slip faults have normal or reverse movement
Dams and Lakes
Dams & lakes are disconnect river channels and can function as local base level controls on stream gradient and store sediment from transporting downstream. They also act as barriers to migrating species, such as fish traveling upstream to spawn, and the controlled water releases alter the downstream ecology of river systems and their floodplains.
Braided Rivers
Braided river patterns occur in high-energy environments that contain an excessive sediment load that is deposited on the bed of the channel. The stream loses the capacity to transport the sediments and it forces its way through the accumulation of sediments forming an interwoven network of channels.
Meandering
Meandering river patterns are low-gradient, sinuous channels that contain multiple, individual meander bends that are laterally migrating across the flood plain.
