Here's why:

* Compression: This term refers to the force that pushes objects together, squeezing them.

* Rock Surfaces: The boundaries between different rock layers or masses.

Examples of Compression Zones:

* Convergent Plate Boundaries: Where tectonic plates collide, causing mountains to form and earthquakes to occur. This is a prime example of a compression zone.

* Folds: When layers of rock are compressed, they can bend and fold, forming a variety of geological structures like anticlines and synclines.

* Reverse Faults: These faults occur when the hanging wall (rock above the fault) moves upward relative to the footwall (rock below the fault). This is a result of compression forces.
