Iwill make you the brainliest use the images on-screen to complete the activity and identify the forces involved in each image of stressed rock. forces used for folded rock near palmdale, ca:

The answer is; compressional force

This type of force causes the particles, of the mass experiencing the force, to compact inwards. This cause the rock layers to  fold. This type of force is experienced by the crust at convergent boundaries where two  tectonic plates are colliding. When the compressional force exceeds the elasticity of the rock layers, faulting occurs.
