The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine ...

Researchers have developed a new deep learning-based workflow that can automatically detect and pick teleseismic phases with ...

How do scientists explore Earth's hidden interior — its crust, mantle, and core? The answer lies in earthquake waves. Like X-rays, these seismic waves travel through and reflect off internal ...

Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed ...

Meanwhile, another ambitious drilling project aims to create one of the deepest holes on our planet, furthering research into Earth’s interior. In this article, we explore these incredible ...

This process - known as “subduction” - carries rocks, water, and carbon dioxide trapped in minerals back into the Earth’s interior where they can drive future volcanic eruptions, continuing the plate ...

Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers. At the planet's heart lies the inner core, a solid sphere of iron and nickel that ...

It’s also closely linked to how heat is released from Earth’s interior. Because of this, plate tectonics is also thought to be intimately connected to the development of life on Earth. The movement of ...

It is the largest spinning model of the Earth’s interior ever built and resembles the Star Wars Death Star, only shinier. Geophysicist Daniel Lathrop wants, among other things, to use it to ...

This recycling of surface materials and volatile elements deep into the Earth's interior, can impact long-term climate stability, atmospheric balance, and the habitability of our planet over ...

Many geologists attribute the great variation in the temperature gradient to complex irregularities in the structure of the earth's crust. Some even maintain that the interior of the earth is cold ...
