An interesting branch of science
From a small age we are interested in the origin of life on Earth. Even small children ask difficult questions, it is not easy to answer at all. Is it easy to answer the age-old question of the origin of the Earth itself? What is its pedigree, who studies this problem, how much did the scientists advance in these studies? .. To talk about this, let us first give a definition of the branch of science that is of interest to us-geology.
The very word “geology” is derived from Greek roots: geo – earth, logos – doctrine, so it is not difficult to explain the content of this science: it covers a number of research directions – the composition, structure and history of the development of the earth’s crust and our planet. The origins of geology belong to the deep antiquity and are associated with the first information about rocks, minerals and ores. In an independent branch of natural science, geology emerged in the late eighteenth – early nineteenth
Today we will talk about historical geology.
On Earth, before the appearance of man over millions of years, events took place that changed our planet. On land, the seas came repeatedly, which blurred and destroyed it. The mountain ranges rising from the sea water were undermined by rain and snow, as well as by glaciers that descended from the mountain peaks. At the bottom of the seas, on islands and on continents, volcanoes erupted a molten lava that covered huge areas, changing the face of the Earth beyond recognition.
The winds in the deserts dispelled the mountain ranges into dust, transferring and depositing the sand masses, and they accumulated on the vast expanses of our planet.
All the changes that the globe has undergone since the earth’s crust was formed on it and up to the present time is studied by historical geology. Historical geology finds out where in the past there were seas and land, studying the places where volcanic eruptions took place.
Historical geology not only establishes events that occurred millions of years ago, studies their sequence. Scientists-geologists are interested in what happened earlier and what later.
