Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

New research has dramatically reshaped our understanding of Earth’s early geological history, overturning traditional beliefs about how the planet’s first continents came into being. Researchers from ...

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

An artistic reconstruction of Earth during the Hadean eon (~4.5 billion years ago). Intense volcanic activity, heat from accretion, and frequent impacts kept the young Earth in a molten state. This ...

Earth's continents are slowly moving across the planet's surface due to plate tectonics, culminating in regions of crustal expansion and collision. In the latter case, high temperatures and pressures ...

The Mid-Atlantic Ridge in Iceland. This area is the boundary between the North American and Eurasian tectonic plates, which move apart ~ 2.5 cm/year. Subduction and the formation of continents, a ...

The history of Earth's continents might be different from what we first thought. The most popular theory of how the continents formed billions of years ago may not be right, according to a paper in ...

There are many open questions about how our planet formed 4.55 billion years ago: When did plate tectonics start? When did the Earth's mantle begin to vigorously circulate in a process called ...
