200 million years from now Mogadishu and Mumbai will be neighbours along a large mountain range.

Why we are predicting the mountains of the far future, and what it can tell us about the world today.
Dating of rocks that once formed some of the world’s first beaches suggests the first large continents grew large enough to rise above sea level roughly 3 billion or so years ago.
Stunning mosaic of oxidised copper in the form of azurite (blue) and malachite (green) in a rock.
Using geology and AI, a virtual model of how the Earth’s tectonic plates have evolved can help reveal deposits of copper.
New research suggests that Venus’ crust is broken into large blocks – the dark reddish–purple areas – that are surrounded by belts of tectonic structures shown in lighter yellow–red.

Researchers used decades-old radar data and found that some low-lying areas of Venus’ crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.
4 billion years ago, the Earth was composed of a series of magma oceans hundreds of kilometres deep.
The rocks provide rare evidence of a time when Earth's surface was a deep sea of incandescent magma.
The greenhouse effect and plate tectonics are essential for maintaining water on the Earth’s surface.

The presence of water on the Earth’s surface is the result of a subtle balance between different mechanisms in the atmosphere and below the surface.
Himalayan rocks hold magnetic clues about their origins.

Earth’s magnetic field locks information into lava as it cools into rock. Millions of years later, scientists can decipher this magnetic data to build geologic timelines and maps.
The present landscape near Dongshen, China.

A big dip in the Earth’s crust may record an ancient continental collision from the dawn of plate tectonics.

Born on July 30, 1920, geologist and cartographer Tharp changed scientific thinking about what lay at the bottom of the ocean – not a featureless flat, but rugged and varied terrain.
Half Dome in California is constituted from granite, a relatively less dense type of rock.
How the earliest continents formed has been a matter of debate. Analysis of zircons in Canada and Australia suggest that those historical processes are similar to current tectonic movements.

New research has found that the continents ended up where they are today because of previous plate tectonic processes that controlled how Pangaea broke apart.

Puerto Rico’s January earthquakes came after many foreshocks and have been followed by numerous aftershocks. Scientists are studying these sequences to improve earthquake forecasting.
On June 5-6, 2012, NASA’s Solar Dynamics Observatory collected images of one of the rarest predictable solar events: the transit of Venus across the face of the Sun.
This hot, acidic neighbor with its surface veiled in thick clouds hasn’t benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.
Material from the Earth’s core has been leaking into the mantle through activity that led to volcanic eruptions such as that helped form the Hawaiian islands.

New findings suggest the core has been leaking for the past 2.5 billion years, and that could help scientists understand how the core was formed.
The quake prompted several buildings to be evacuated in central Darwin.
Because it happened within the Australian Plate rather than at a plate boundary, shockwaves from the quake travelled more efficiently to Darwin than to cities closer to the epicentre.
Scientists have pieced together Game of Thrones’ geology as the show draws last breath on television.

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.
Lord Howe Island is part of a volcanic seamount formed around 7 million years ago.
Lord Howe Island is part of an underwater volcanic chain much older than first thought, with the possibility of new islands still to form.
The beaches of Koh Phangan are set within rocky crags made of granites, the type of rocks studied to piece Thailand to Australia.
Australia’s slowly heading north to one day become part of Asia, but a study of the rocks tell us that’s not the first time there’s been a connection.
A combination of tectonic plates, geography and poor infrastructure make Indonesia vulnerable to deadly tsunamis.
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.
