Usage: geology; technical; plural form

Examples

• Epeirogeneses have shaped the topography of stable continental interiors over millions of years.
• Geologists study epeirogeneses to understand how continents rise and sink without major deformation.
• The formation of broad plateaus and basins results from epeirogeneses rather than mountain-building tectonics.
• Multiple epeirogeneses during the Paleozoic created the vast inland seas that covered North America.
