The evolution of our Earth is the story of its cooling: 4.5 billion years ago, extreme temperatures prevailed on the surface of the young Earth, and it was covered by a deep ocean of magma. Over ...

Geologists studying some of the planet's oldest volcanic rocks have uncovered new evidence that water was playing a major role in shaping Earth's interior and driving volcanic activity more than 3 ...

Scientists discovered a rock in Papua New Guinea that plunged more than 90 kilometers beneath Earth's surface, revealing a ...

When Earth first formed, around 4.5 billion years ago, it was an extremely hot, largely molten planet. As it cooled, heavier materials sank to form the core, while lighter materials formed the mantle ...

Materials scientists at the University of California San Diego have performed powerful laser shock experiments on a perovskite mineral to better understand the geophysical processes in Earth's deep ...

Examining how plates move in Earth's mantle and how mountains form is no easy feat. Certain rocks that have sunk deep into Earth's interior and then returned from there can deliver answers. Examining ...

The journey for volcanic rocks found on many volcanic islands began deep within the Earth. Brought to the Earth’s surface in eruptions of deep volcanic material, these rocks hold clues as to what is ...

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...
