One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that suggests ...

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.6 billion years. Mountains have been built and eroded, continents and oceans have moved ...

There's no doubt that humans have had a powerful impact on the planet, but some scientists believe the effects are so clear and widespread that our current time period should be declared the dawn of a ...

For the first time, scientists have evidence that a layer deep beneath Earth's surface can create volcanoes. The layer, known as the transition zone, lurks in Earth's mantle between 250 and 400 miles ...

The Earth with the upper mantle exposed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock approximately 100 miles beneath the Earth's ...
