“It’s as if the soil was erased under our feet”: the land bark disappears slowly without anyone realizing it – Environne2b

The earthly bark, the basic element of our planet, disappears under our feet, often without being aware of it. This phenomenon, although invisible daily, is of capital importance to understand the inner dynamics of the Earth. Research conducted by experts as Dr. Brenhin Keller of the University of Dartmouth made it possible to emphasize fascinating and often unknown processes. Thanks to the In -Deph study, we find out how the ocean bark, by far static, moves and interact with the continental bark, thus continuously modifying the surface of our planet.

Subduction process: Key mechanism

Phenomenon Subduction It is central to understand the disappearance of the Earth’s crust. This process, which was discovered during the revolution of tectonic plates at the age of 60, describes how the ocean bark moves under the continental bark. This movement is explained by the fact that the ocean bark when aging, cools and becomes denser. As a result, it eventually sinks under the continental bark, more stable. This is this mechanism that explains the presence of explosive volcanoes in regions such as Andy or JapanWhere subduction is particularly active. Scientists continue to study these areas to better understand the consequences of these movements on our environment and related risks.

Complexity

Unlike what one might think, the inner structure of the Earth is far from simple. For example, the ocean bark does not exceed 180 million years due to its tendency to subduction under the continental bark. This process also leads to the transport of sedimentIt descends into the coat can melt and form new magms. These phenomena show that Earth is constantly evolving, with geological cycles that continuously transform its surface. Dr. Keller emphasizes the importance of these interactions to understand the tectonic processes that shape our planet.

The idea received: an earthly cloak

The extensive but incorrect idea is that the earth’s coat is made up of liquid magma. Actually The coat is a crystalline solidcomposed mainly of glass minerals. Although it is very hot, it does not behave like a liquid, but rather as a solid, which flows very slowly, a pace comparable to the growth of human nails. This characteristic is caused by extreme temperatures and pressures that rule at these depths. This clarification is essential for full understanding of the internal dynamics of our planet and preventing erroneous simplification of often mediated.

The consequences of subduction and recent discoveries

Research of subduction and the composition of the country has deep consequences for our understanding of geological phenomena. They allow us to better understand the seismic and volcanic risks that are exposed to certain regions of the world. In addition, these discoveries stimulate innovations in methods of monitoring and preventing natural disasters. Understanding tectonic processes is also necessary for the permanent use of natural resources And better to plan the future of our planet in the face of climate change.

The disappearance of the Earth’s crust under our feet is a phenomenon that reminds us of the complexity and dynamics of our planet. Although we continue to explore and understand these fascinating processes, what new discoveries could we make from the secrets of our world?
