Web14 feb. 2024 · Stress is a force that affects an object, and strain is how the object responds to it. Various common forces that operate on Earth impose stress on geologic materials. Gravity does, and currents of water or air do, and the tectonic movements of the lithospheric plates do. The stress of gravity is called pressure. WebA) Axial stretching: tension is applied far from the crack. B) Hydraulic fracturing: tension or compression is applied far away from the crack and fluid pressure increases, causing tension on the face of the cracks.
