giving them different properties. Do other planets have the same kinds of layers as the Earth? We think that the other rocky planets (Mercury, Venus, Mars), our moon, and some of the other larger ...

This is made possible by measuring sound waves that are created by earthquakes and pass through Earth’s layers. By analyzing how the different layers cause the sound waves to slow down ...

The monumental finding suggests the Earth has five major layers instead ... core changed the speed of those waves in a different way than the layer above it, the center core’s outer shell.

Seismic waves travel at different speeds through Earth’s different layers depending on its density, temperature and composition. Like a radiologist studying a patient’s internal organs ...

This layer is a part of the asthenosphere ... By analyzing the data, Hua saw how the seismic waves moved through the different materials beneath Earth’s crust, including changes in speed ...

"These results help us better understand how the inside of the Earth operates and how the different layers of the system interact as a whole," the authors said. "Such multi-decadal oscillations ...

The monumental finding suggests the Earth has five major layers instead ... core changed the speed of those waves in a different way than the layer above it, the center core's outer shell.

The findings can help researchers understand how different layers beneath the Earth function.
