Tectonic map of the Earth. The first continental crust on Earth formed more than 3 billion years ago. Likely the first fragments formed by partial melting and re-crystallization of the primordial ...

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; ...

The discovery of an unexpectedly hot rock beneath Earth's surface is challenging scientists' understanding of how heat is ...

Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

Using information from inside the rocks on Earth's surface, we have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth's geological record has ...

Map of the Earth showing tectonic plates. Early Earth likely had no plate tectonics, but a solid outer crust with no tectonic activity covered the entire planet. After being broken up by convection ...

Study of 4 billion year old crystals reveals insights into the early Earth environment and hints at early plate tectonics. Tiny crystals found in an Australian rock formation may be the key to ...

Earth has six continents not seven, radical study claims ...

The Earth with the upper mantle revealed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock in a key region just below the tectonic ...

The activity of the solid Earth – for example, volcanoes in Java, earthquakes in Japan, etc – is well understood within the context of the ~50-year-old theory of plate tectonics. This theory posits ...
