Compression, decrease in volume of any object or substance resulting from applied stress. Compression may be undergone by solids, liquids, and gases and by living systems.What does 'compression' mean?
Compression is a force that squeezes something together. Materials are only useful if they can withstand forces. How do you know when to use tension or compression? If the magnitudes of a calculated force is positive and it is pointing away from the joint, you have tension. If it is negative and pointing away from the joint you have compression.What does compression mean in Earth Science?
Compression is a type of stress that causes the rocks to push or squeeze against one another. It targets the center of the rock and can cause either horizontal or vertical orientation. In horizontal compression stress, the crust can thicken or shorten. In vertical compression stress, the crust can thin out or break off.
