Early Earths internal structure, artwork

Early Earths internal structure. Artwork of a hemispherical cross-section through the early Earth, with thin oceanic crust and formation of the first continental landmasses. The outer and inner core are at lower right. Convection in the mantle (circular arrows) drove volcanic activity and crustal spreading. The first continents arose where oceanic crust accumulated and thickened over areas of mantle down-welling. Stable continents first formed around 2.5 billion years ago, 2 billion years after the Earth formed. It would be another 2 billion years before complex marine and land life would evolve, with plate tectonics continually reforming the shape of the continents

EDITORS COMMENTS
This artwork titled "Early Earth's Internal Structure" takes us on a visual journey through the geological history of our planet. Against a striking black background, we are presented with a hemispherical cross-section of the early Earth, revealing its intricate layers and processes. At first glance, we notice the thin oceanic crust that covers the surface, while below it lies the molten rock of the mantle. Circular arrows symbolize convection in the mantle, driving volcanic activity and crustal spreading. It is within these dynamic forces that the first continental landmasses begin to form. The outer and inner core are depicted at lower right, reminding us of their immense heat and pressure deep within our planet. This artwork beautifully captures how plate tectonics continuously reshape our continents over billions of years. Stable continents emerged around 2.5 billion years ago, two billion years after Earth's formation. However, it would take another two billion years for complex marine and land life to evolve alongside these ever-changing landforms. Through this mesmerizing illustration by PLANETARY VISIONS LTD/SCIENCE PHOTO LIBRARY, we gain insight into Earth's prehistoric past – a time when volcanic eruptions shaped landscapes and oceans teemed with undiscovered wonders. It serves as a reminder that beneath our feet lies an ancient story waiting to be uncovered by scientists dedicated to understanding our planet's rich geological heritage.
