About this item
| Description: | Fifty years ago people imagined the Earth as a solid planet, unchanged for millions of years, until plate tectonics showed continents drifting 25cm each year. Mapping continental velocities using the Global Positioning System makes land look more like a glacier than a rigid plate. See how the Earth’s vigorous movements in the mantle that maintain these motions show us 50 years on that the Earth is a fluid, not a solid, sphere. With Professor Dan McKenzie. |
