Compression.
Tensile force / stress.
A force that acts on rock to change its shape or volume called stress. Tension is the stress that sketched rock so that is becomes thinner in the middle.
The stress force that causes a mass of rock to pull or twist in opposite directions is called tension. Shearing is the stress force that causes a mass of rock to pull or twist in opposite directions.
The stress force that causes a mass of rock to pull or twist in opposite directions is called tension. Shearing is the stress force that causes a mass of rock to pull or twist in opposite directions.
Folded mountains are formed when rock layers are bend under stress.
Folded mountains are formed when rock layers are bend under stress.
The squeezing together of rocks by stress is called compression. In scientific terms Compression is when a force called stress pushes rock/squeezes rock together until it folds or breaks.
The force that squeezes a rock until it folds or breaks is called compression. When enough stress builds up in a rock, the rock can break, and create a fault.
Geological stress is a force applied to a rock.
Tensile stress.
The force causing the change in the shape of rock is called stress. The change of shape in the rock is called strain. If the stress does not cause a permanent change in the shape of rock, it is called elastic deformation. If the change is permanent, it is called plastic deformation.
When rock layers are folded, a geological fold happens. These folds form under various conditions such as stress, hydrostatic pressure, pore pressure, and temperature gradient.
