Question

Объяснение зависимости расположения крупных форм рельефа и месторождений полезных ископаемых от строения земной коры на примере Восточно Европейской равнины.Ребятушки помогите срочно,заранее огромное вам спасибо!!

Answer 1

В основании В-Европ. равнины лежит платформа, а в пределах платформ, как правило, залегают осадочные полезные ископаемые, поэтому здесь в восточной части залежи нефти, газа, угля. А в западной части - выступы кристаллического фундамента - Балтийский щит на с-з и Воронежский массив на ю-з. В их пределах - залежи магматических п/и.Железная руда - Курской магнитной аномалии, руды Карелии и Кольского полуострова (железные, медные, никелевые)

Dependence of the Location of Major Landforms and Mineral Deposits on the Structure of the Earth's Crust: The Example of the East European Plain

The location of major landforms and mineral deposits is influenced by the structure of the Earth's crust. The East European Plain provides an example of how the structure of the Earth's crust can affect the distribution of landforms and mineral resources in a region.

The East European Plain: The East European Plain is a vast lowland region that stretches across several countries in Eastern Europe, including Russia, Ukraine, Belarus, and Poland. It is characterized by its relatively flat terrain, with few significant landforms such as mountains or hills.

Structure of the Earth's Crust: The Earth's crust is the outermost layer of the Earth, and it is composed of various types of rocks and minerals. The structure of the Earth's crust can vary from region to region, and it plays a crucial role in determining the distribution of landforms and mineral deposits.

Tectonic Activity: Tectonic activity, which includes processes such as plate tectonics and volcanic activity, plays a significant role in shaping the Earth's crust and creating landforms. In regions with active tectonic activity, such as mountain ranges or volcanic areas, landforms like mountains, valleys, and volcanoes are more likely to be present. These landforms can also be associated with the presence of mineral deposits, as certain geological processes can concentrate minerals in specific areas.

Sedimentary Deposits: The East European Plain is primarily composed of sedimentary rocks, which are formed through the accumulation and compaction of sediments over time. Sedimentary rocks often contain valuable mineral deposits, such as coal, oil, and natural gas. The presence of these deposits in the East European Plain can be attributed to the geological history of the region, including the deposition of organic matter in ancient seas and the subsequent transformation into fossil fuels.

Glacial Activity: Glacial activity, including the movement of glaciers and the deposition of glacial sediments, can also influence the distribution of landforms and mineral deposits. During the Pleistocene epoch, the East European Plain was covered by extensive ice sheets, which shaped the landscape and deposited sediments. These glacial deposits can contain valuable mineral resources, such as sand, gravel, and clay, which are used in construction and other industries.

Conclusion: In summary, the location of major landforms and mineral deposits in the East European Plain is influenced by the structure of the Earth's crust. Factors such as tectonic activity, sedimentary deposits, and glacial activity have shaped the region's landforms and contributed to the presence of valuable mineral resources. Understanding the relationship between the structure of the Earth's crust and the distribution of landforms and mineral deposits is essential for geological exploration and resource management in the East European Plain and other regions around the world.
