Geomorphological factors and processes

Geomorphological factors and processes:
      The geomorphological process as mentioned (Geomorphic Proccess) is a way to influence the earth rocks and it consists of forms and include all the process of physical and chemical changes that have a role in the change and remove or composition of the Earth forms.
      The factor geomorphological (Agent) is the process becomes effective under it, which means that any broker naturally capable of carving, transport and deposition of material that make up the earth's crust and rocks of different types, and therefore, the current and underground water, waves and currents are geomorphological factors, sometimes called factors animated as they move the material and the deposition borne elsewhere. And that directs these factors is gravity, but gravity is not considered geomorphological factor (These factors are also called virtual agents) can be summarized overall geomorphological processes that occur in the Earth's crust in the following manner:
1. weathering Weathering
2. avalanche Mass Wasting
3. settlement Gradation
4. Sculpture (demolition) Degradation
5. erosion (drifting) Erosion include running water + underground water + waves and sea tides Great marine, waves and currents + wind + refrigerators.

6. construction Aggradation include running water + underground water + waves, currents and tides and sea waves and the vast wind and refrigerators and all organisms, including humans, and underground operations.
7. crustal movements Diastrophisim (displacement and crawl)
8. volcanic activity Vulcanism
9. processes that originate outside the atmosphere, Extraterrestrial, such as the fall of meteors and meteorites.
         It must be emphasized that confusion by using terms that are called by the common factors and geomorphological processes may occur. The confusion is due to some extent to the difference of opinion about what should be covered by certain geomorphological process. So using the word settlement (Gradation) to include all geomorphological processes that are working to make the surface of the Earth's crust one level, and include two sets of the settlement process of the operations: the first works to reduce the level of the earth's crust called the demolitions, and the second is working to raise the level of the earth's crust called the construction operations. As for the process of erosion (drifting) may be synonymous with the settlement of this process, including the removal of material so you do not enter the transmitter with it an integral part of the erosion. But the word collapse (avalanche) indicative transferring large-sized block of rock Mufttat by direct gravity towards the bottom of the slopes, and helps the presence of water on the occurrence of collapse. While the process of weathering the expansion of the concept to a large degree for this process to reflect part of the erosion though they may not share the work weathering he spoke without causing erosion, and erosion are possible without precedent weathering, so Valtjoah previous process and the process of preparing to erosion, but it is not a prerequisite for the occurrence Stripping.
The time factor in the geomorphological processes (geological time):
      The study of some of the Earth's surface forms currently require some simple knowledge of previous geologic other times, as the worker or geomorphological process not be able to accomplish session except over a long time called the geological-time. Normally, this measure beyond the extent of the human lifespan to a great end, from here it is necessary to take the time factor into consideration when studying the Earth's surface appearances, and so Valmkies time here should be different from the scale used in human events, where it is despite the fact that some geomorphological processes occur quickly and suddenly, such as volcanoes and earthquakes, but this is the anomaly, not the rule, because most of the manifestations and forms of the earth's surface is formed slow manner and over geological periods so that man is not able to notice the changes which occur.
An estimated geologists age of the earth that has become a planet solid his soles and crust of about 3000 million years ago, and that about 85% of this period is almost a mystery not known to have only very little information, note that there is an abundance of information on the ground in the last period of its history a period which amounts to 500 million years, and that most of the Earth's surface notable appearances due to this late period of earth's history, and there are timetables such as Natal agenda, and it must consult this list to keep track of the different geological accidents, and I've ages geological estimated in these tables according to the analysis of chemical and radiological materials, metal carried out by geologists with it the percentage of error in the estimate. The tables are divided geological time periods to: time (ERA) geologist like Albaliosek which contains Periods (stages) and is divided into eras periods
