Rocks contain a layer-by-layer record of the history of our planet.
As strange as it sounds, rocks are made from stardust.

Even in this fantasy world, geological processes like tectonic plate movement, earthquakes and volcanic eruptions would have built the mountains, carved the rivers, and created vast oceans.
Photographed on Kangaroo Island, this rock – called a ‘zebra schist’ – deformed from flat-lying marine sediments through being stressed by a continental collision over 500 million years ago.
Giant forces slowly move continents across a viscous layer of the Earth, like biscuits gliding over a warm toffee ocean. This stresses the continents, and twists and contorts the crust.
Scientists have predicted four supercontinent scenarios - but which is the most likely?
The Tianshan mountains frame Sayram Lake in the Bortala Prefecture in Xinjiang, China.
Setting the scene for ancient Silk Road trading and now China's Belt and Road initiative, the Tianshan has changed humanity. Geological evidence shows us how this incredible mountain range formed.
A combination of tectonic plates, geography and poor infrastructure make Indonesia vulnerable to deadly tsunamis.
The 2016 Kaikoura earthquake shattered the surface and twisted railway lines.
Research shows that satellite GPS measurements could provide a better tool for earthquake forecasting.
Luckily, monitoring systems at Hawaii’s Kilauea volcano allowed some warning before fissures opened up in 2018.

Melbourne lies at the eastern end of a volcanic province, but when's it going to blow? Understanding the geology of Melbourne and comparing it to Hawaii is really helpful in calculating risk.
Feeling blue? An Oppenheimer Blue diamond of 14.62 carats.
Some diamonds come from depths of more than 650km. Tiny imperfections in these gems give us clues about what's happening in Earth's hidden geological layers.
Shallow but powerful earthquakes on Lombok have resulted in around 100 deaths and destroyed buildings.
Caught in the middle: Lombok and Bali are exposed to earthquake and tsunamis risk due to a tectonic plate boundary to the south, but also a unique zone of activity that thrusts to the north.
What’s going on 150 kilometers below the Earth’s surface?

A new array of seismometers provides a glimpse of what's happening deep beneath this geologic fault. New data help explain why the north and south of the region are more seismically active than the middle.
Lifeguards and volunteers run across an ash covered slope after the June 3 eruption of the Fuego volcano in Guatemala.
Important points about volcanoes: location matters, explosiveness can be predicted to an extent, and fast-moving flows of volcanic materials (known as pyroclastic flows) are deadly.
InSight aims to figure out just how tectonically active Mars is, and how often meteorites impact it.
What is Mars made of? We hear from a scientist who will be part of the team analysing 'marsquake' seismic data and orbital imagery from the InSight mission to the red planet.
Seismic shockwaves after a meteorite’s collision could affect systems all over the planet.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.

The Nov. 12 earthquake wasn't centered on any known major faults in the Earth's crust. In its wake, scientists will collect data to add detail to what they know about seismic activity in the area.

Human-induced earthquakes have been reported from every continent except Antarctica. We asked a geologist to investigate whether North Korea's nuclear tests could trigger geological changes.
The new map was created using data from rocks found in locations including Madagascar.
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.
