Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost layer. This thin shell represents less than one percent of Earth's total mass, yet it's the only layer we ...

Scientists have discovered yet another layer deep inside the core of the Earth, a new study suggests. "Traditionally we've been taught the Earth has four main layers: the crust, the mantle, the outer ...

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

A study by researchers at the Australian National University (ANU) suggests the existence of a distinct fifth layer within Earth's inner core, termed an "innermost inner core," located approximately 3 ...

There is more to Earth than what we can see on the surface. Both the exterior and interior regions of the planet are made up of many layers with various properties. These layers are formed because of ...

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

Deep inside Earth, far below the crust and oceans, lie vast hidden regions that many geophysicists suspect could have shaped the conditions for life at the surface. I cannot verify specific scientific ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth's inner core, according to seismologists. Data captured from seismic waves caused by earthquakes ...

While this new layer is difficult to observe, its existence may point to an unknown, dramatic event in Earth's history. Investigating the structure of the inner core can help us understand more about ...
