Places where rocks have been compressed into bends by colliding plates are called folds.

Here's a breakdown of the terms:

* Folding: The process of rock layers being bent or curved due to compression forces.

* Folds: The resulting bends or curves in the rock layers.

* Colliding Plates: When tectonic plates move towards each other, they exert compressional forces on the rocks at their boundaries.

These folds can range in size from microscopic to massive, creating features like:

* Anticlines: Upward folds, resembling an arch.

* Synclines: Downward folds, resembling a trough.

* Monoclines: Gentle, one-sided folds.

So, when you see a landscape with folded rocks, you're witnessing the dramatic results of plate tectonics shaping the Earth's surface!
