Four billion years of Continent Evolution: Why planet Earth is unique: Professor Hugh Rollinson
25 February 2009
Podcast
During the lecture Hugh addresses the question of how continents form, and why this process makes Earth unique as a planet. In detail the lecture demonstrated that continent formation in the early Earth (billions of years ago) was different from modern continent-forming processes. This observation provided a new solution to a long-standing paradox about the Earth's crust's average composition and opens up new research questions about how processes at the Earth's surface are linked to those in the Earth's deep interior.
