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 ...

Researchers studied how the universe’s structure changed over time. They found that the universe is less clumpy than expected ...

"We found evidence that may indicate a change in the structure of iron, which suggests perhaps two separate cooling events in Earth's history," Stephenson said. "The details of this big event are ...

Seismic velocities depend on the material properties such as composition, mineral phase and packing structure, temperature ... Molten areas within the Earth slow down P waves and stop S waves because ...

Iron is one of the main elements found in the Earth's inner core, which is characterized by extremely high temperatures and ...

The radius of the Earth is 6371 km. It has an average density of 5.5 g/cm3. Figure 1: Structure of the Earth's Interior The structure of the Earth’s upper mantle can be derived from seismic waves. The ...

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.

"We found evidence that may indicate a change in the structure of iron, which suggests perhaps two separate cooling events in Earth's history," Stephenson said. "The details of this big event are ...
