Standing strong despite weathering!

Weathering is a natural process that breaks down rocks, soils and minerals within the Earth’s surface. When looking at the Bernese Alps, one can come to a conclusion that rock decay plays a major role in forming the shapes seen through the Alp range. There is no doubt that the formation of the Alps was due to tectonic movements, but the process of weathering cannot be ignored. Due to the severe cold winters and warm summers, signs of physical weathering such as frost wedging are apparent. This occurs when water freezes within rock fractures, forcing it to expand and create a crack form shape. The Bernese Alps sees temperatures varying single digits in the winter and an average 80F in the summers.   

Other signs of physical weathering include abrasion, which is the process of rocks grinding together causing mechanical weathering. Due to the Bernese Alps peaking at a high altitude of around 14000 ft, the presence of glaciers help the process of abrasion. Glaciers are a mixture of ice, rocks and minerals, and as gravity pulls it down, it grinds along side other rocks and minerals. The largest glaciers found within the Swiss Alps rage are found in Jungfrau-Aletsch protected area, which is suited in the Bernese Alps. Glaciers in some parts of the Bernese Alps cover as much as 45.9 square mile.

As the glaciers melt during the summer season, it flows down towards four major rivers that surround the Bernese Alps; rivers Aar, Saane, Rhone, and Reuss.  This brings us to the hydrology of how these rivers act as main water supply to these alp regions. The drainage patters in the Swiss region is classified as dendritic, where the water is spread through different branched streams. These streams circulate through our Switzerland and play a major role in distributing water supply.

Bernese Alps tectonic development

To understand the significance of why the Bernese Alps have a unique shape, one must understand the history behind the Alps formation. The Swiss Alps were formed when the African plate moved towards the plates located in Europe and Asia also known as the Eurasian Plates. This collision caused the mountains to form, which dates back to 100 million years ago. As large as the Alps might seem geologists still refer to the Swiss Alps as “young mountains”, in comparison with the developments of other mountains around the world.

This tectonic tension is still active, and it’s causing the Alps mountain range to increase in size and matter. Geologists say that the Alps are developing in height at a rate of 1mm per year. This is mainly due to the convergent movements of the Eurasian and African plates.

The Bernese Alps have one of the most distinct shapes amongst the Alps mountain line up. Its highest peak named Finsteraarhorn has a measured height of 14026 ft. This makes it 1000 ft shy from the highest peak in the Swiss Alps range. Rivers surround parts of these Alps from the south and north. Towards the north we find lake Thunersee, which stretches towards the capital Bern. On the on the other side lies Rhone River which flows towards France.  

The majority of these Alps are made up of three main rock types which are; limestone, marble and granite. 
The structure and physical geography of the Bernese Alps shows no harm to people due to the fact that it’s far away from populated areas. Although, with its rough structures and rock formation tourists and skiers must be advised. The rocks present in the Bernese Alps could be profitable and useful for people interested in the rock industry.

A little about me..

Hello and welcome to my blog!

My name is Abdulaziz Al-Thani and this is my third semester here at UCD. I am majoring in Business Human Resource Management and the reason why I chose this major was because my future goals in the businesses world and my fascination towards anthropology. I love the study of people and understanding how and why people react in certain ways is very important in creating a social and welcoming work environment.

A little about me, I come from a country in the Middle East called Qatar, and I have traveled a lot to Europe and lived in Switzerland for a short time when I was young. I have studied English at a very young age as well as French, Arabic being my first language. I finished my college diploma in the College of the North Atlantic and transferred to UCD beginning of this year.

The place I chose for my blog posts is the Bernese Alps located in a city called Grindelwald in Switzerland. I chose this area because of how beautifully shaped the mountains are and this will allow me to evaluate the geography behind why it's shaped like that and eventually use the knowledge gained throughout the course to predict the future of these Alps.
