Geomorphology:
Is the branch of geology and geography which studies the landforms of the terrestrial surface and their explanation, modeled by the external geological agents. It studies the climatology, hidrography, pedology, glaciology and other biological and anthropic phenomenon on the relief.
The facts that influends on the relief are:
- Climate: it determine the agents that will act.
- Lithology: the branch of geology that studies the composition, shape... of the rocs and indicate the agents that act.
- Human: is the most life criature that infludes directly or indirectly.
Hi! today I´m going to post some information about Glacials, and more concrete about the Perito Moreno.
Glacials are huge amounts of ice formed by accumulation, compression and freezing of snow. That can move across the land and we can find them at hight latitudes and altitudes. We use them to know the evolution climate in that area.
It´s a glacial located in the Department "Lago Argentino" in the province "Santa Cruz", in the southest of Argentina in the region "Patagonia".
It has a front of 5 km and an altitude of 60 metres from the water floor. Thanks to it constan advance dams the water of the lake its next to.
Because of the pressure this liquid mas produces leaks in the ice that create a tunnel with a vault of more than 50 metres that finally falls in an inusual natural show in the "National Park of Glaciers", where are 356 glacials. This fracture isn´t an uncommon process, it has repeated a lot of times, the last was the 2 of March 2012, it has past four year from the one before. The averaged of fractures it´s every five years.
It has a speed of 2 metres every day, 700 metres every year.
In the glacial just exist little insects called "Andiperla Willinki" and there aren´t many.
Hello I hope you like this section, and today 3/12/12 I´m going to continue it posting something about the national natural reserve of Ordesa and Monte Perdido, where I went last summer on holidays.
Monte Perdido.
The national park it´s located at the Pyrenees in the region of Sobrarbe, Aragón (Spain). It takes the municipalities of Bielsa, Fanlo, Puértolas,Tella-Sin, Torla and Broto. But Monte Perdido it´s situated at the North of Huesca, in the centre of the Pyrenees.
It´s the oldest calcareous massif in Europe, it´s biggest peak has an altitude of 3.355 metres from the sea, but it has two more peaks Cilindro (3.328 m) and Añisclo (3.263) also called Soum de Ramond in honor of one of the first explorers. But there are also 22 peaks with more than 3.000 metres.
The massif of Monte Perdido it´s constituded by four valleys: Ordesa (Southwest), Añisclo (South), Escuaín (Southest) and Pineta (Est).
A little part of the massif it´s in France and we can emphasize the Valley and Circus of Gavammie, another glacial circus that forms the biggest waterfall in Europe more than 400 metres of vertical fall.
At the North Face of Monte Perdido we can see one of the few glacials that continue existing on the Pyrenees, but it´s moving back, it consist on a Glacial Tongue with 750 metres and goes from the 2.700 to 3.250 metres.
