(PhysOrg.com) -- For most of modern science, researchers have believed that the Earth was primarily made up of enstatite chondrites, a subclass of meteorites. This was because of the similarity of chromium, nickel and oxygen ...
Geologists have long known that around 155 million years ago, a 5,000 km long piece of continent broke off western Australia and drifted away. They can see that by the 'void' it left behind: a basin hidden deep below the ...

The rocks at the surface of the modern Earth are broadly divided into two types: felsic and mafic. Felsic rocks are generally relatively low density—for a rock—and light in color because they are made from whitish minerals ...
