These are deposits of shallow seas, lakes, rivers, glaciers, and wind—blown formations. Many parts of the land periodically began to be covered with ice. The Cenozoic era is divided into Paleogene, Neogene (combined into the Tertiary period) and Quaternary periods. The modern Quaternary (anthropogenic) period in the history of the development of the planet's nature is characterized by noticeable changes in the coastline of continents and especially sharp repeated changes in warm and cold climatic epochs.

In cold epochs, powerful continental glaciations captured vast surfaces, then in warm epochs the glaciers disappeared completely or sharply decreased. These changes largely explain the peculiarity of the dynamics of the settlement of wildlife not only on continents, but also in marine basins. Abrupt interruptions of fauna remains are observed in the sediments of enclosed basins (seas and lakes) located in glaciation sites. Cold and warm epochs caused its repeated redistribution over the surface of continents and oceans.


The culmination of the development of the organic world of the Quaternary period can be called the appearance of a person who, having passed through several stages of development from a pithecanthropus to a modern person, is capable of a wide variety of highly qualified mental and physical labor. The appearance of man marked a completely new stage in the history of the development of the planet's nature. An essential element of conscious, purposeful transformation of nature is introduced. The scale of this transformation is increasing every year. The shown features of the species composition of the animal and plant world of the Earth underwent all kinds of changes not by themselves, but in isolation from other components of nature.

The whole appearance of the planet's nature was changing, the proportions of all the shells of the Earth were changing, from the airy to the very dense central shells of its interior. At the same time, these changes did not take place over the entire surface in the same way and unambiguously. In this regard, rock formations that differ in thickness, composition, and content of paleontological remains help to determine spatial changes in the development of nature over the same time periods.

The plains of Karelia, the Keiva plateau, and the Khibiny mountains are only the peneplenized bases of the once-high mountains that have turned into sections of the Baltic Shield. The formation of the Baltic Shield began in the early period of the development of our planet. In the Archean and Proterozoic eras, 1600-500 million years ago, the Kola Peninsula and Karelia experienced powerful mountain-building movements that swept vast areas of the modern continent of Europe. The oldest crystalline rocks were crushed into folds, exposed to high temperatures and pressure.
