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

We finally know where two giant blobs in Earth's middle layer came from — and they're a mismatched pair. These strange regions in Earth's mantle, known as "large low velocity provinces" (LLVPs), are ...

The deep oceans are far from flat. They feature ridges, trenches, seamounts, and valleys, creating a diverse and dramatic ...

The discovery bolsters the theory that meteorite impacts played an important role in Earth's early geological history Margherita Bassi Volcanologists are closely monitoring the 11,070-foot-tall ...

New research led by a York University professor sheds light on the earliest days of Earth's formation and potentially calls ...

Extraction of the continental crust has left the Earth's mantle depleted in certain elements. Some rocks from the Arctic Ocean floor suggest that the extent of depletion and heterogeneity in the ...

It creates the Earth's magnetic field and is about 1,400 miles (2,300 kilometers) thick. The next layer is the mantle. Many people think of this as lava, but it's actually rock. The rock is so hot ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

There's a lot of debate about what LLVPs are. Some studies have suggested that they're material from the ancient Earth — either a layer of primordial unmixed rock from the planet's formation or ...
