Our earth. Pushing and shoving

Our earth. Pushing and shoving / [presenter Ben Young] ; [narrator Karina Kelly] ; [writer/producer Dick Beilby].

Volcanoes and earthquakes are only part of a bigger picture. Tectonic forces also push continents around and cause mountains to be uplifted. The crust recycles itself. The lighter rocks of the continents float on the heavier rocks of the mantle.
