Scientists have long thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see ...

Interactions between Earth and the solar system have profoundly shaped the planet’s history, influencing evolution and climate. One striking example is the asteroid impact 66 million years ago ...

The study also provides a new approach to solving one of the biggest enduring scientific mysteries: when did plate tectonics begin?

Tajika and his team used a numerical model to simulate key aspects of biological, geological and chemical changes during the late Archean eon (3.0–2.5 billion years ago) of Earth's geologic history.
