The geological time scale at Haua Fteah shows major climatic changes that occurred during the Pleistocene. 4. Hardly, Wilson said : " On a geological time scale , ( exfoliation is ) fairly common. 5. Coarse grained rocks are formed very slowly, while fine grained rocks are formed quickly, on geological time scales . 6. Thus, Arthur Holmes'report concluded that radioactive dating was the only reliable means of pinning down geological time scales . 7. Macroevolution includes changes occurring on geological time scales , in contrast to microevolution, which occurs on any time scale. 8. However, these are very slow processes that occur in geological time scales ( hundreds of millions of years ). 9. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales . 10. The diagram below presents a contemporary ( 2010 ) view of feliform evolution and familial relationships ( geological time scale .
