Earth Once Swallowed Its Own Superocean. Could It Happen Again?…

The ancient supercontinent of Rodinia turned inside out as the Earth swallowed its own ocean some 700 million years ago, new research suggests… Read the rest of the article here at Live Science: https://www.livescience.com/64707-earth-swallowed-superocean.html Advertisements

Will There Ever Be Another Pangea?…

(Intro from Live Science) Just before the dawn of the dinosaurs — roughly 251 million years ago — Earth’s continents abutted one another, merging to form the supercontinent Pangea. That land mass, which straddled the equator like an ancient Pac-Man, eventually split into Gondwana in the south and Laurasia in the north… Read the article here: https://www.livescience.com/63753-will-there-be-another-pangea.html

Continental Drift: Theory & Definition…

Intro:  Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents… Read all about the theory here at livescience.com: https://www.livescience.com/37529-continental-drift.html

Ancient Earth’s hot interior created ‘graveyard’ of continental slabs…

Summary from sciencedaily.com: Plate tectonics has shaped the Earth’s surface for billions of years: Continents and oceanic crust have pushed and pulled on each other, continually rearranging the planet’s façade. As two massive plates collide, one can give way and slide under the other in a process called subduction. The subducted slab then slips down […]

Earth probably began with a solid shell… 

Summary:  Plate tectonics — a defining feature of modern Earth and the driving force behind earthquakes, volcanoes and mid-ocean spreading ridges — did not start until later in Earth’s history, new research suggests. The work is the latest salvo in a long-standing geological debate: did plate tectonics start right away, or did Earth begin with […]

Heat from earth’s core could be underlying force in plate tectonics… 

Summary:  For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth’s core. The new findings also challenge the theory that underwater mountain ranges known […]

Scientists uncover insights into the formation of Earth’s oldest continental crust…

Addressing fundamental unknowns about the earliest history of Earth’s crust, scientists have precisely dated the world’s oldest rock unit at 4.02 billion years old. The findings suggest that early Earth was largely covered with an oceanic crust-like surface.
