Earth’s 1st continents arose hundreds of millions of years earlier than thought

Earth’s first continents, known as the cratons, emerged from the ocean between 3.3 billion and 3.2 billion years ago, a new study hints. 

This pushes back previous estimates of when the cratons first rose from the water, as various studies suggested that large-scale craton emergence took place roughly 2.5 billion years ago.
