Answer:
Sometimes folding forces layers to bend.
Step-by-step explanation:
- The layers underlying the Earth's surface are generally subjected to intense forces acting upon them from all the sides.
- These forces are usually the maximum when there is an occurrence of tectonic plate activity.
- During a tectonic plate activity, the layers are left with no room to move, and as a result, tectonic folding ends up in permanently deforming the layers by bending them.
