Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...

Due to evolutionary pressures and the light spectrum available to photosynthesizing cyanobacteria on early Earth, the world’s oceans were likely much greener than they are today. Although the ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...
