Question

В чём отличие земной коры от лттосферы по мощности составу и строению

Answer 1

Литосфера – это твердая оболочка Земли, включающая земную кору и верхнюю часть мантии. Земная кора (материковая и океаническая) – твердая каменная оболочка Земли, состоящая из твердых минералов и горных пород.

Answer 2

Difference between Earth's Crust and Lithosphere in terms of Power, Composition, and Structure

The Earth's crust and lithosphere are both important components of the Earth's structure, but they differ in terms of power, composition, and structure.

Power: - The Earth's crust is the outermost layer of the Earth and is relatively thin compared to the other layers. It has an average thickness of about 35 kilometers on the continents and about 7 kilometers beneath the oceans. - On the other hand, the lithosphere is a broader and more comprehensive concept. It includes not only the crust but also the uppermost part of the mantle. The lithosphere is divided into tectonic plates, which are large pieces of the Earth's lithosphere that move and interact with each other. The thickness of the lithosphere varies, but it is generally thicker than the crust, ranging from about 100 to 250 kilometers.

Composition: - The Earth's crust is primarily composed of rocks, minerals, and elements such as silicon, oxygen, aluminum, calcium, sodium, and potassium. It is divided into two types: continental crust and oceanic crust. The continental crust is thicker and less dense, consisting mainly of granite rocks, while the oceanic crust is thinner and denser, composed mainly of basalt rocks. - The lithosphere, as mentioned earlier, includes not only the crust but also the uppermost part of the mantle. The uppermost part of the mantle is composed of solid rock, which is rich in iron and magnesium. This composition is different from the crust, which is primarily composed of rocks and minerals.

Structure: - The Earth's crust is divided into several tectonic plates, which are rigid pieces of the Earth's lithosphere that move and interact with each other. These plates are responsible for the formation of various geological features such as mountains, valleys, and ocean basins. The movement and interaction of these plates also give rise to earthquakes and volcanic activity. - The lithosphere, as mentioned earlier, is divided into tectonic plates. These plates are not fixed but are constantly moving. The movement of these plates is driven by the convective currents in the underlying asthenosphere, which is a partially molten layer beneath the lithosphere. This movement of the plates is responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.

In summary, the Earth's crust is the outermost layer of the Earth and is relatively thin compared to the lithosphere. The crust is primarily composed of rocks and minerals, while the lithosphere includes not only the crust but also the uppermost part of the mantle. The lithosphere is thicker than the crust and is divided into tectonic plates that move and interact with each other. The movement of these plates is responsible for various geological phenomena.
