Within ancient rocks in Arizona's Petrified Forest National Park, scientists have identified signs of a regular variation in Earth's orbit that influences climate. Here, one of the authors near the research site.

Earth’s orbital changes have influenced climate, life forms for at least 215 million years.

Plate tectonics shape our planet, creating structures from canyons to mountain ranges.

Why parts of Earth have barely changed in 3 billion years.

Vast reserves of rare earth elements have been found hidden in deep-sea mud. Enough has been found to feed global demand on a 'semi-infinite basis,' and provide a much needed boost to the tech industry.

‘Semi-infinite’ trove of rare-Earth metals that can be used to create everything from phones to electric cars is found in Japanese waters.

Researchers found that when the supercontinent Nuna broke apart the rock on which Georgetown sits did not drift away and instead became a new piece of Australia.

Ancient rocks reveal part of Australia was once connected to Canada to form the giant supercontinent ‘Nuna’ that broke up 1.6 billion years ago.

The Havre submarine volcano is more than 2,000 feet (650 meters) below sea level and is the site of the largest underwater eruption of the past century.

Little-known deep sea volcanic eruption that took place just 600 miles from New Zealand was the world’s largest in 100 years.
