Detailed explanation-1: -Shearing – stress that pushes a mass of rock in two opposite directions. Tension – pulls on the crust, stretching rock so that it becomes thinner in the middle like warm bubble gum. Compression – squeezes rock until it folds or breaks like a giant trash compactor.
Detailed explanation-2: -Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). Compression is the most common stress at convergent plate boundaries. Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart.
Detailed explanation-3: -Compression: Stress which causes rock to squeeze or push against other rock. Tension: Stress which occurs when rock pulls apart or gets longer. Shear Stress: Stress which occurs when tectonic plates move past each other causing rock to twist or change shape.
Detailed explanation-4: -Compression. Compression (squashing) occurs as tectonic plates are pushed together and the crust becomes shorter and thicker, building mountain ranges like the Alps or Himalayas. The rocks are folded and metamorphosed at depth. They may be faulted nearer the surface.
Detailed explanation-5: -Shearing-the stress that pushes a mass of rock in two opposite directions. Tension-the stress force that pulls the crust, stretching rock so that it becomes thinner in the middle.
