Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of ...

According to plate tectonics theory, Earth's outer shell is divided into multiple plates that slowly glide over the mantle. This slowly changes Earth's surface over time by merging, or separating, ...

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 ...

Forces acting inside the Earth have been constantly reshaping the continents and ocean basins over millions of years. What Alfred Wegener published as an idea in 1915 has been accepted since the 1960s ...
