| Rocks and geological structures exhibit a mixture of compressional and extensional stress effects. |
| A series of compressional and extensional tectonic events created the present geologic structure and physiography. |
| The first indication of an earthquake is often a sharp thud, signaling the arrival of compressional waves. |
| The compressional warming that occurs as the air descends creates vast regions of subtropical high pressure. |
| Bent specimens show folds on the compressional but not the extensional side, indicating that walls were originally flexible. |
| The seismograms from earthquakes recorded at stations all over the world are analyzed to derive compressional and shear wave velocity and density as a function of depth. |
