Before it split into the continents we know today, Earth was home to just a single landmass, or "supercontinent," called Pangea. Over tens of millions of years, as the familiar story goes ...
More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure—have been found on Earth. They are formed of simple ...
