Evolution of the Earth, artwork
Evolution of the Earth, artwork. The Earths internal structure is shown in the insets, with the corresponding state of the Earths crust across top. At left, from 4.6 to 2.3 billion years ago, the mantle only had weak convection currents (dotted lines) and a fluid core-mantle boundary. The surface was cratered and barren. At centre, from 2.3 billion years ago, soil and oceans form. Post-perovskite forms the core-mantle boundary, reinforcing convection cells. Volcanism begins. At right, 1 billion years ago, convection within the iron core forms a magnetic field. Plate tectonics begins, and mountains, an atmosphere, and life form

EDITORS COMMENTS
The captivating artwork titled "Evolution of the Earth" takes us on a mesmerizing journey through our planet's geological history. This stunning print showcases the changing face of Earth, highlighting its transformation over billions of years. Intriguing insets reveal the internal structure of our planet, depicting how it evolved from a barren and cratered surface to a thriving hub of life. The leftmost section portrays a time when weak convection currents flowed within the mantle, while at the core-mantle boundary, there existed a fluid interface. Moving towards the center, we witness an incredible shift as soil and oceans begin to form. Convection cells are reinforced by post-perovskite, leading to volcanic activity that shapes our landscape. Finally, on the right side of this remarkable illustration lies an era approximately one billion years ago. At this stage in Earth's development, convection within the iron core generates a magnetic field crucial for sustaining life as we know it today. Plate tectonics come into play alongside mountains forming and an atmosphere taking shape. This thought-provoking artwork not only offers us insight into Earth's past but also serves as a reminder of its continuous evolution. It showcases how various elements such as volcanism, tectonic activity, and magnetic fields have shaped our planet throughout history. As we gaze upon this print from Science Photo Library, we are reminded that every inch of land beneath our feet carries with it an awe-inspiring story millions or even billions of years in the making.
