| 1. | The southern boundary is a mid-oceanic ridge, the Galapagos Rise.
|
| 2. | The drilling is at a rifted plate margin on the mid-oceanic ridge.
|
| 3. | Rifts are oceanic ridges formed when tectonic plates separate and a new crust is created.
|
| 4. | Transform faults move differently than a strike-slip fault at the mid-oceanic ridge.
|
| 5. | It has been observed that 3 He is present in volcano emissions and oceanic ridge samples.
|
| 6. | Iceland is the largest landmass ( 102, 775 km?) situated on an oceanic ridge.
|
| 7. | The geological deformation of Iceland is mainly caused by the active spreading of the mid-oceanic ridge.
|
| 8. | The chemical composition of metabasalts in the CBMZ is similar to that of mid-oceanic ridge basalts ( MORB ).
|
| 9. | The most prominent examples of the mid-oceanic ridge transform zones are located in Atlantic Ocean between South America and Africa.
|
| 10. | A profound consequence of seafloor spreading is that new crust was, and still is, being continually created along the oceanic ridges.
