What is and what is Geomorphology for?

Geomorphology is a science whose object of study is the irregularities of the earth's surface, or simply the different forms of relief.

It serves to show the importance of the study of relief for the different fields of knowledge (urban and regional planning, environmental analysis…), highlighting the close relationship with geography and the geographical context, considering its contribution to the process of territorial planning.

Very similar plant and animal fossils have been found in Brazil and Africa. US, Siberia and China coal reserves have very similar properties. This is no coincidence. It was first explained by Wegener and his theory of Drift Continental.

At the end of the Carboniferous period, there was a single immense continental mass called Pangea (Pangeia). In Pangea, North America was linked to Eurasia, and South America linked to Asia. Australia and Antarctica were joined together, and India, for its part, was perfectly nestled between Africa and Australia.

Pangea Configuration

The division began more or less in the Jurassic period, forming two super continents: the Laurasia and the Gondwana. At the beginning of the Tertiary period, South America separated from Africa and then North America from Laurasia. India kept moving towards Asia. Australia and Antarctica were linked.

The modern configuration of the continents took place 65 million years ago, with the junction of the Americas, the separation of Australia and Antarctica and India clashing with Asia. The continents were separated by the oceans.

The theory of Continental drift gave way then to the theory of Plate Tectonics, which in addition to consolidating Wegener's ideas, allowed her to explain how this process occurred. With the mapping of the marine dorsals, where it coincides with the areas of volcanism and terrain, the theory was created that the earth's crust is divided into plates that interact with each other, generating the most varied phenomena.
