GeoJeopardy! Fridays #82

Time for GeoJeopardy! Fridays, because it has been a little while so I will do another one.

- The Earth -

An atoll is a circular one of these that has grown around a sunken volcanic island

  It's believed the Earth is over 4.5 billion yrs. old, based on 4.6 billion yr. old rocks found on this neighbor


 Dolomitization is the process by which this rock, including its fossils, turns into dolomite


Term given to the tundra's always-frozen soil layer


Until this 19th century French scientist, no one had proved the Earth rotated

All the answers as well as any other previous GeoJeopardy! questions can be found over at my website by clicking the link.
