1. of, relating to, or involving compression or the act of compressing
Usage: commonly used in technical and scientific contexts
2. relating to seismic waves that travel by compression and expansion of rock material
Usage: geology and seismology

Examples

• The compressional forces in the Earth's crust cause mountains to form.
• Compressional stress can lead to structural failure if not properly managed.
• Seismologists use compressional waves to detect earthquakes deep underground.
• The material underwent compressional testing to measure its strength.
• Compressional deformation altered the rock layers over millions of years.
