How many continents does Earth really have? While most of us learned there are seven, new geological research suggests the ...

For decades, the end-stage life of a subduction zone existed only in theory. Now, for the first time in geologic history, scientists are bearing witness to the Juan de Fuca Plate tearing apart and ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Oct 29, 2025, 03:16pm EDT Nov 01, 2025, 01:11pm EDT For the first ...

A new study presented at the 2025 EPSC/DPS Joint Meeting proposes that the rarity of specific geological and atmospheric conditions necessary for technologically advanced life significantly limits the ...

The closest technological species to us in the Milky Way galaxy could be 33,000 light years away and their civilization would have to be at least 280,000 years, and possibly millions of years, old if ...

Rocks in Australia preserve evidence that plates in Earth’s crust were moving 3.5 billion years ago, a finding that pushes back the beginnings of plate tectonics by hundreds of millions of years.

Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

Things may be moving on Venus’ surface. In 1983, researchers discovered that the planet’s surface was speckled with strange, circular landforms. These rounded mountain belts, known as coronae, have no ...

Earth is the only known planet which has plate tectonics today. The constant movement of these giant slabs of rock over the planet’s magma creates continents – and may have even helped create life. In ...

On Earth, the land moves. Over millions of years, continents shift and the entire surface of the planet reshapes itself. The driver of all this is plate tectonics: Earth’s surface is divided into ...

Plate tectonics is geology’s Theory of Everything. The realisation in the 1960s that Earth’s crust is made of fragments called plates—and that these plates can grow, shrink and move around—explained ...
