The geological and topographical features that make up the world we live in are shaped in large part by faults and fractures in Earth’s brittle crust. Faults arise from preexisting microscopic imperfections within rock. When the rock is subjected to increasing stress, tiny cracks form at these imperfections. The cracks grow and interact until the rock suffers larger-scale damage.
