Cratonization – how did the Archean cratons form?
Earth History1. Getting Started Cratonization refers to the process by which stable continental crust, known as cratons, formed during the Archean eon, approximately 4 to 2.5 billion years ago. Archean cratons are the oldest and most persistent parts of the Earth’s continental lithosphere, and their formation played a critical role in shaping the early geology of

Plate Tectonics vs Continental Drift: Debunking the Contradiction
Earth HistoryPlate tectonics and continental drift are two closely related theories that have helped scientists understand the dynamic nature of the Earth’s crust. While plate tectonics is a relatively new theory, the idea of continental drift has been around for over a century. Continental drift was first proposed by Alfred Wegener in 1912, and it suggested
