WebEarths crust is constantly recycling and renewing due to the process of seafloor spreading and subduction along plate boundaries. New crust is formed by seafloor spreading and recycled at subduction zones (trenches) along convergent boundaries. This process results in a constant cycle of renewal and recycling of Earths rock - we call the rock ... Earth formed approximately 4.6 billion years ago from a disk of dust and gas orbiting the newly formed Sun. It formed via accretion, where planetesimals and other smaller rocky bodies collided and stuck, gradually growing into a planet. This process generated an enormous amount of heat, which caused early Earth to melt completely. As planetary accretion slowed, Earth began to cool, forming its first crust, called a primary or primordial crust. This crust was likely repeatedly destro… def extented playWebIceland is particularly well suited for research in this field, being one of few places on Earth where these processes can be observed above sea level.
