Volcanologists study the formation and eruptions of volcanoes - surely one of the most interesting jobs around. However, it can also be very dangerous.
The earth’s own magnetic field offers a useful way to measure the age of rocks - information that can help unpack ancient events and aid our understanding of the present.
Latest development in ‘Crete feet’ find serves as a reminder of the challenges facing dig sites.
Earth’s thermostat can fail spectacularly at times. Around 700 million years ago, huge volcanic eruptions triggered “Snowball Earth”.
A special combination of rain, rocks and subsea volcanoes makes the sea salty.
A new study can’t rule out the possibility that human ancestors lived on Crete at the same time as they evolved in Africa.
This sudden, 150,000-year long temperature spike has many parallels with modern climate change.
Humpback whales are deterred from their migration routes by the noise of air guns used to survey the ocean floor for oil and gas deposits, a new study has found.
How can life on Earth help us understand life in space? To answer this question, we compare biological clocks and geological rocks and find that they tick uniformly.
Gas buried in the Northern Territory’s Velkerri Shale was produced in a “slime world” that existed nearly a billion years before the first complex life on Earth evolved.
You would not recognise Earth if you saw it 500 million years ago - the lands, oceans, climate and life were all very different. Scientists now have a new map of the deep history of Earth.
One of Australia’s most distinguished palaeontologists will be farewelled at a funeral in Canberra today.
Researchers are looking at whether devastating asteroid strikes are predictable or random.
Mercury found in prehistoric rock bolsters the idea that volcanoes caused a mass extinction 200m years ago.
There is a direct correlation between the age of the builder, spade size and the speed at which boredom sets in.
In the wake of the collapse of Malta’s spectacular arch, which UK coastal features are under threat from the unrelenting forces of wind and water?
Reports claim the feature has vanished – but then mountains are always changing shape.
Signals from violent earthquakes are helping reveal the landscape of the planet’s insides.
Almost half a million years ago a huge flood started breaking the apart the land bridge that joined England and France.
