8. Ask the students to recall how scientists use seismic wave observations to investigate the interior structure of the Earth. This is similar to checking the ripeness of a melon by tapping on it.

Differences in seismic wave paths through layers of Earth ... explain why some experimental evidence has been inconsistent ...

The Earth has a layered structure, including the core ... but can cause earthquakes and volcanoes where they meet. The seismic waves produced by an earthquake are monitored and tracked.

EGU, the European Geosciences Union, is Europe’s premier geosciences union, dedicated to the pursuit of excellence in the ...

Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed ...

By studying how those seismic waves move through the Earth ... the monitoring stations show that the ancient structure surrounding Earth’s core has valleys and mountains, as the material ...

Researchers are now trying to understand the "innermost inner core" of the Earth by studying how seismic waves travel through the Earth.

Infrasound can be used to investigate the internal structure of our planet, just like ultrasound is used for foetal scanning. Earthquakes produce very powerful seismic waves that can be classed as ...
