To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

Earth's interior is made up of a series of layers that sit below the surface crust. In order of depth, these layers include the solid, but flowing mantle, the liquid outer core and the solid iron ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could transform our understanding of plate tectonics.

By Alimat Aliyeva Scientists from the United States and China have concluded that the Earth's inner core has changed sh ...

For decades, scientists have been building up a better picture of Earth's interior by using seismographs ... "With the new high-resolution model, we can see such anomalies everywhere in ...

Our planet's interior is much too deep ... on seismic waves to understand and model its structure. Seismic waves are shock waves that propagate through Earth's layers after an earthquake or ...

For the doctoral student, this means above all that more research with even better models is needed to see further details of Earth's interior. "The waves we use for the model essentially only ...
