Structure, process and stadia are important factors in the
discussion of geomorphology. Discussion of a region is not complete if one of
them is not dealt with (ignored). In the preceding discussion, it has been
noted that three factors are known as the basic principles of geomorphology,
whereas in this portion will be clear again, how the meaning and position of
these three factors in the study of geomorphology.
1 Structure
To learn landscape form a region, then the first thing to
note is that the geological structure of the area. As already noted, that the
geological structure is an important factor in the evolution landscape and it
is reflected in the structure of the earth, it is clear that landscape an area
controlled / controlled by geological structures. In addition to the geological
structure, are the properties of rocks, among other things whether the rocks
are fractures (stocky), presence or absence of the field layer, fracturing,
friability, porosity and permeability properties of rocks from one another.
According Thornburry, that understanding the structure of
the geomorphology has a wider sense, while Lobeck distinguish between
"Structural Geology" and "Structure Landscape". Some term
geological structure: horizontal structure, dome structure, fracture structure,
structure folds, volcanic structures; Some of the term structure landscape:
plains or plateaus, hills dome, mountains faults, folds mountains, mountain
complex. Because the structure is determined by the structure landscape
geology, where the geological structure occurs by endogenous force, the
structure can be interpreted as a form landscape landscape caused by endogenous
style.
2 Process
Many experts, such as Worcester, Lobeck, and differ in
interpreting Dury on the definition of geomorphological processes, they assume
that what is meant by the process here is a process that comes from within and
outside the Earth (endogenous processes and process eksogenik), some are
thought process here is the energy that comes from outside the Earth (exogenous
force) only. The notion here is energy process that works on the earth's
surface that come from outside the Earth (exogenous style) and not from the
earth (endogenous style).
Definition of "geomorphic Processes" solely
inspired by the energy / process derived from
extraterrestrial, the reason is:
1. The energy comes from the earth (endogenous style) is
more likely as a factor that builds, such as the formation of plains, plateaus,
mountains dome, mountain folds, faults mountains, and volcanoes.
2. The energy of extraterrestrial origin (exogenous force)
is more likely to change the shape or
landscape structure.
Style damage that causes any stage phases or
"stages" on every kind landscape. Stage or stage is not caused by
endogenous style like diastrophisme or vulcanisme.
Undeniably, that is both stylish (endogenous and exogenous),
which is also known as endogenous processes and process eksogenik have a
dominant influence in the formation of a specific landscape on this earth,
therefore the genetic history landscape divided into two major categories yes
it is:
1. Landscape contruksional, ie all landscape formed by style
endogenous (exogenous force has not worked here, so it is
still at the initial level).
2. Landscape destruksional, ie all landscape formed by exogenous
force against landscape generated by endogenous style, through the process of
weathering, erosion, abrasion, and sedimentation.
Thus it can be explained that the definition of prose here
is all the styles that affect the destruction (recast) landscape form resulting
from endogenous style allowing landscape experience stadia Young, Adult, and
Elder. Landscape reform process occurs through the river (fluvial processes),
glaciers, waves, and wind. All four were referred to as dynamic agents (mobile
agents / geomorphic agent) because they can erode and transport materials in
the earth and then precipitation in certain places.
.3 Stadia
Stages / levels landscape (wheel geomorphic)
declared to know how far the level of damage that has occurred and the stage /
stage what landscape condition today. To state levels (treadmill geomorphic)
used the term: (1) Young, (2) Adult and (3) Old. Each level in the
geomorphology characterized by certain traits specific, not determined by age landscape
