Humanity’s influence on the moon is so great that we should define a new geological epoch, just as we are doing on Earth with the creation of the Anthropocene, researchers argue. We should also create ...

Earth’s history spans 4.54 billion years, and scientists use the geologic time scale to divide it into eons, eras, periods, and epochs. By studying rock layers, fossils, and isotopes, they can ...

A group of scientists has chosen a small lake near the U.S.-Canada border as the site that best represents the Anthropocene Epoch—a proposed period of geologic time marked by humans’ drastic impact on ...

The Triassic period stands out in Earth’s history as the time when dinosaurs first evolved. It was followed by the Jurassic and Cretaceous periods – at the end of the latter, the dinosaurs were wiped ...

The classic technique for assessing the history of a rocky planet’s geology is to count craters. On average, areas with longer exposure to space have had more impacts, and therefore more craters. By ...

No work on any science has yet been published in our language more exhaustive of facts, more clear in statement, or more philosophical in general character and arrangement, than Dana’s “ Mineralogy,” ...

The study of ecological dynamics would benefit greatly from a tripartite research effort similar to that used so successfully in climate and ocean dynamics (see Figure 2.1), where information about ...
