A subject from the career

Hello friends,

Now I'm concerned to show you about a subject from the career I've studied. The subject I'm going to talk about is the Local Climatology and it was taught by the teacher Mauro.
Some important legacies in knowledge that let me the subject was for example the Palaeoclimate which it describes the different atmospherical stages since the creation of this air layer (approximately 4 billion of years ago) until conditions similar to nowadays (after the last Ice age) with their evidences as in pollen as in ice cores. Besides the Palaeoclimatology makes attempts to find the causes of the big climates changes throughout the Earth history by the movements of this planet respect to the Sun or the volcanic activity. Of course, it had impacts in the distribution of living beings (which it's probable they had similar patterns that the current ones but at a different scale, all depending of whiat kind of animal or plant was the dominant one in the world) as in the continents as in specific zones for example the both sides of a mountain or a valley. Additionally, it had impacts in the topography during the Ice ages. For example, when glaciers were bigger and they had a major distribution in the world they were able to change the shape of valleys intensely. Some of the evidences are the Norwegian fjords, Southern Chilean fjords or many valleys in the Andes and the Alps.
What I liked most about the course was about the topics themselves which they were completely interesting to answer many questions about the nature.
Undoubtedly, what I disliked a little about the course is sometimes I was sleepy during the class.
Thanks to this course at last I could understand about the rhythm of growing of plants according to climatic conditions and calculate the day of their germination.
