The relief model
IndexKinds of relief model
Fluvial model (rivers)Torrential model (torrents)Glacier model (glacier)Karstic model (subterranean
water)Litoral model (swell) Eolic model (wind)
Fluvial modelForm narrow pass, flood plains and wave-cut platform. This areas are very goods for the farming and the human occupation.
Form valleys with “V”In Spain this kind of erosion is very frequent.
Narrow pass river Cares (Picos de Europa)
Fluvial model
Fluvial modelFlood plains (River Pas and
Narcea)
Fluvial modelWave-cut platform (River
Cinca)
Fluvial modelMeanders of a river (Valle en
artesa)
Fluvial modelValley with form “V”
Torrential modelIt type of relief model is very
erosive and origin beautiful landscapes.
Origin relieves like canyons and carcavas.
When are accumulated the erode materials form alluvial fans erosions.
They aren´t good areas for the population and farming.
Torrential model Carcavas Tabernas desert
(Almería)
Torrential model Almadenes Canyon (Cieza) Río
Lobos Canyon (Soria)
Torrential modelWaterfalls and rapids. They are
very frequents in high mountains.
Torrential modelRavines and narrow pass. The
aggressive erosion origin for the water and the materials that the water bring, form the ravines.
Glacier modelThis kind of model is origin in
high mountains areas, very colds zones.
The human occupation is very small and this areas normally are touristic.
The glacier valley has got “U” form and it has got quite population.
Form glacier cirques and other forms.
Glacier modelGlacier cirques. Origin for the
accumulation of ice.
Glacier model“U” form valley origin form the
weight of the block of ice.
Glacier modelGlacier erosion.
Glacier modelKinds of erosion in the glacier model. Glacier spite, morren and glacier
cirque.

Glacier model
Glacier modelGlacier lake. Typical in post-
glacier landscape
Glacier modelErosion in rocks. The water
infiltrate in the rocks, and when is freeze, this water occupy more, and the rock is broken.
Karstic modelIn areas forms for limestone or
plaster, the water infiltrate in crack, and it dissolving the rock and form galleries and caverns.
There are two types: - Superficial: origin form
the dissolution and the roof of the cavity like dolines.
- Subterranean.
Karstic modelGalleries and caverns
Karstic modelWhen the water is infiltrate can
produce stalactites and stalagmite for the calcium carbonate dissolved in the water.
Karstic modelDolines.
Littoral modelThe swell is an agent very
erosive. When the swell is more
aggressive form cliffs, capes and ledges.
When the swell is not very aggressive form beaches, the place where the eroded materials are accumulated.
When the cliffs are eroded form abrasion platforms.
Littoral modelCliffs. Platform abrasion.
Littoral modelCliffs. Platform abrasion.
Littoral model Formation of cliffs.
Littoral modelWhen there is a cliff can origin
arches.
Littoral modelIn the littoral model can origin
beaches, tombolos and arrows.
Littoral modelLittoral lakes.
Eolic modelIn Spain this model is not very
important, but the wind transport the sand accumulated in the beaches, origin coastal dunes.
Is predominant in deserted zones.
When the wind carry the sand and the clay form rocky deserts.
When there are sedimentation of sand, is origin dunes field.
Eolic modelThe particles in the wind origin
corrosion in rocks so the rocks have got different shapes.
Eolic modelRocky deserts.
Eolic modelDunes fields.
