By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner ...

Recently, scientists have discovered that the Earth's inner core thought to be in a solid state and also an unchanging sphere, may have undergone significant shape changes over the past 20 years.

Scientists have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

Earth's inner core is slowing down, changing shape CTV science and tech specialist Dan Riskin joins CTV Your Morning to chat about how Earth's inner core affects both humans and the planet. CTV ...
