Geophysicists at ETH Zurich are using models of the lower mantle to identify areas where earthquake waves behave differently ...

The Earth has a layered structure, including the core, mantle and crust. The crust and upper mantle are cracked into large pieces called tectonic plates. These plates move slowly, but can cause ...

The sound snow makes when you step on it changes too. In the freshly fallen dry snow of the Southwest, loose-touching flakes make a soft "whoof" with footfall. But as it gets colder, snowflakes ...
