My favourite geography subject
Hello blogheads!

Today my post is committed to talk about my favourite geography subject. Keeping on mind all geography subjects I studied in this career during those semesters, I notice my favourite one is geology. This subject is taught by Rodrigo Rauld in the second semester.

I specially like this subject because I like mostly the physical side of geography as a way of knowledge, thanks to geology now it's possible to understand and explain step by step many elements present in either landscape (as within Chile as in abroad) that always were a doubt before getting the course, in few words an example could be why does the Grand Canyon have lines in both cliffs. Besides it's interesting because I saw that all elements on the Earth surface such as water (solid or liquid), wind or sand are substantial to mould the relief or the tectonic forces are capable to create it (for example the existence of the Andes, Alps or the Himalayas).

Therefore, about things I've learnt to, geology was the best instance to make sense about phenomena present in the planet where we live, for example the existence of The Andes or the Caledonia mountains, fossils of many kinds of life within the history of the Earth (with the help of the palaeontology), the presence of different stages which make to order the events decisive for the whole world (The Paleozoic, the Mesozoic,etc), the kinds of volcanoes (why the lava of a Hawaiian/Icelandic volcano is different to a Chilean one), what consists precisely in an earthquake (keeping on mind we live in the world's most seismic country) or why are there minerals of many characteristics (for example the granite has a volcanic origin while the limestone is a chemical sediment very easy to dissolve it in water).

An curious piece of information is that I always remember is the difference between a rock and a stone, which the first one was moulded by the nature while the second one was modified by humans (here it makes me sense why in the world history exists the Stone Age within the Prehistory).
