When tension pulls rocks apart it creates a what?
normal faults
Tension in Earth’s crust pulls rock apart, causing normal faults. In a normal fault, the fault is at an angle, so one block of rock lies above the fault while the other block lies below the fault.
Which type of stress occurs when rocks are being pulled apart?
tension
Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries. When forces are parallel but moving in opposite directions, the stress is called shear (figure 2).
What can tension cause the formation of?
Fault Block Mountains: Tension force pulls rock apart causing normal faults. Two normal faults cut through a block of rock, the hanging wall between each slips downward, the rock between moves upward, forming a fault-block mountain.
What force pulls and stretches rocks?
Tension
Tension The stress force called tension pulls on the crust, stretching rock so that it becomes thinner in the middle.
What happens in a rock will it break and or slip apart Why?
Tension stress pulls rocks apart. Tension causes rocks to lengthen or break apart. Tension is the major type of stress found at divergent plate boundaries. Shear stress happens when forces slide past each other in opposite directions (Figure below).
What is tension stress on rocks?
In geology, the term “tension” refers to a stress which stretches rocks in two opposite directions. The rocks become longer in a lateral direction and thinner in a vertical direction. One important result of tensile stress is jointing in rocks.
What is tension in rocks?
What could tension forces produce on the surface of the planet?
Stress causes the build up of strain, which causes the deformation of rocks and the Earth’s crust. Compressional stresses cause a rock to shorten. Tensional stresses cause a rock to elongate, or pull apart.
When rocks move slip and separate from each other energy release in a form of?
Faults
The energy released is an earthquake. Figure 11. Faults are easy to recognize as they cut across bedded rocks. Slip is the distance rocks move along a fault.
