Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust ...

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, continents. Here, we used ...

For millions of years, Earth’s shifting plates have shaped continents, formed oceans, and built towering mountain ranges. But some of these colossal structures have vanished into the depths of the ...

The plates make up Earth's outer shell, called the lithosphere. (This includes the crust and uppermost part of the mantle.) Churning currents in the molten rocks below propel them along like a ...

Myanmar’s location between two tectonic plates – the India and Eurasia plates – places it at particular risk of quakes.

After suspecting the presence of a series of underwater volcanoes near the Cook Islands, researchers have now mapped out the ...

Tectonic plates float on the semi-solid mantle, which moves very slowly as ... of the Earth's different layers in this quiz. Just over 300 years later, in 1912, the German geologist Alfred Wegener ...

Intraplate volcanism, or volcanism occurring away from plate boundaries ... compared these maps of mantle water to locations where intraplate volcanism occurred over the past 250 million years.
