While many rocks don’t burn, some of them do. It depends on what the rocks are made of – and that’s related to how they were formed. Rocks that burn when they get heated up are combusting. This means ...

The first continents on Earth formed between 3 and 2.5 billion years ago. Geologists studying the oldest rocks found on Earth believe that partial melting, fueled by the heat released during the decay ...

Layers of sedimentary rock are often studied to recreate Earth's history. But rocks aren't always the most reliable historians. New research shows that environmental conditions can substantially ...

Several billion years ago, the oceans were probably not as hot as often assumed, but were instead at much more moderate temperatures. This is the conclusion of a research team from the University of ...

Rocks store information from long ago. For instance, their composition can reveal the environmental conditions during their formation. This makes them extremely important in climate research. This led ...

Our Earth is around 4.5 billion years old. Way back in its earliest years, vast oceans dominated. There were frequent volcanic eruptions and, because there was no free oxygen in the atmosphere, there ...

Hidden beneath farmland in the central tablelands of New South Wales lies one of Australia’s most extraordinary fossil sites – McGraths Flat. It dates back between 11 million and 16 million years into ...
