Concept and geological cycle process:
The geological cycle: the set of phenomena that affect the surface crust and mantle are considered to be chained process steps in time.
3 processes are considered:
Gliptogénesis : Destruction of relief, caused by the action of external agents
lithogenesis: Production of new types of rock materials: from the debris originated in gliptogénesis and materials incorporated in the mantle.
Orogeny: Formation of relief: uniqueness of mountain ranges, with all the accompanying phenomena;
All the above processes occur so simultaneous and permanent , worldwide. You have not completed a process to start another.
For their study will be divided into:
external geological processes
internal geological processes
external geological processes
agents external geological model and destroy tending relief.
The single action external geological agents tend to level the earth, turning it into a vast plain, over the million de años que vienen actuando lo habrían conseguido.
Los agentes geológicos externos son:
La erosión : Es el proceso de desgaste de la roca del suelo intacto (roca madre), por acción de procesos geológicos exógenos como las corrientes superficiales de agua o hielo glaciar, el viento o la acción de los seres vivos.
El transporte : es el arrastre de materiales por las corrientes superficiales de agua y hielo glaciar, o por la acción del wind
Sedimentation: is the process by which solid material transported by ice, running water or wind, is deposited on the river bottom or in areas of lower energy .
internal geological processes:
have their main origin in the planet's internal heat, considering building, to be responsible for the formation of the relief.
can be of two types:
Slow movements:
The manifestation of domestic agents is performed in slow motion u (orogenic).
Jerky:
Earthquakes and volcanoes, which also give rise to the formation of new minerals and rocks latter.
EYE!
External A Geologic Process (eg Transport) is the result of several geological agents external (eg water, air ..)
energy from an external source on the planet
SOL should fundamentally
occur where nuclear fusion reactions and comes in the form of electromagnetic waves :
can be:
Harmful to living things
Visible
high frequency waves (heat)
gamma rays, X rays, ultraviolet rays
(harmful to humans)
The gamma (γ) is a type of electromagnetic radiation, and therefore made up of photons, produced by radioactive elements.
Because they possess high energy, gamma rays are a type of radiation can penetrate matter more deeply.
Given their high energy can cause serious damage to the cell nucleus, so they are used to sterilize medical equipment and foodstuffs.
designated X-rays of electromagnetic radiation, invisible, able to pass through opaque bodies and impress photographic film.
UV Rays:
invisible electromagnetic waves are high energy. released by the sun and some special lamps.
In small doses are needed to determine vitamin D, but in larger doses can damage the skin and eyes. The ozone layer of the atmosphere protects us from this radiation.
visible waves
They are perceived by our eyes and are used to realizar la fotosíntesis
Los rayos infrarrojos son la Emisión de energía en forma de ondas electromagnéticas en la zona del espectro situada inmediatamente después de la zona roja de la radiación visible.
La radiación infrarroja puede detectarse como calor.
Debido a la distancia de la Tierra al Sol 150 millones de Km solo recibimos una billonésima parte de la energía liberada por este, pero es suficiente para...

Cause the atmospheric circulation.
