A geological phenomenon is a phenomenon which is explained by or sheds light on the science of geology. Examples of geological phenomena are:
Mineralogic phenomena Lithologic phenomena Rock types Igneous rock Igneous formation processes Sedimentary rock Sedimentary formation processes (sedimentation) Quicksand Metamorphic rock Endogenic phenomena Plate tectonics Continental drift Earthquake Oceanic trench Phenomena associated with igneous activity Geysers and hot springs Bradyseism Volcanism Earth's magnetic field Exogenic phenomena Slope phenomena Slump Landslide Weathering phenomena Erosion Glacial and peri-glacial phenomena Glaciation Moraines Hanging valleys Atmospheric phenomena Impact phenomena Impact crater Coupled endogenic-exogenic phenomena Orogeny Drainage development Stream capture
