How does compressional stress change a rock body quizlet?
How will compressional force change a rock body? rocks will change shape due to pressure but return to their original state when pressure is released. Ductile Deformation. causes a permanent change in shape or causes a change of shape that does not return to its original shape after the stress is released.
What refers to the changes in shape or position of a rock body in response to differential stress?
deformation. refers to the changes in the shape or position of a rock body in response to differential stress.
Which of the following deformation features is are created by compressional stresses?
Reverse and thrust faults are both the result of compressional stress.
Which tectonic boundary is associated with tensional stress?
Tensional stress happens at divergent plate boundaries where two plates are moving away from each other. Shear stress is experienced at transform boundaries where two plates are sliding past each other.
What are the three ways a rock body might change as a result of deformation?
Three kinds of differential stress occur.
- Tensional stress (or extensional stress), which stretches rock;
- Compressional stress, which squeezes rock; and.
- Shear stress, which result in slippage and translation.
What force causes folding?
Terms in this set (61) Which type of force causes folding? compressional force.
What are the three main types of stress in rock?
Stress is the force applied to a rock and may cause deformation. The three main types of stress are typical of the three types of plate boundaries: compression at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries. Where rocks deform plastically, they tend to fold.
What are the three components of deformation?
The total amount of deformation between two converging bodies is described by the three components of the displacement field: translation, rotation, and strain.
What is tensional stress?
Tensional stress is the stress that tends to pull something apart. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.
What are examples of deformation?
When rocks are stressed, the resulting strain can be elastic, ductile, or brittle. This change is generally called deformation. Elastic deformation is strain that is reversible after a stress is released. For example, when you stretch a rubber band, it elastically returns to its original shape after you release it.
Where does ductile deformation occur?
Ductile deformation occurs in the deeper regions of the Earth due to two comtributing factors – pressure and temperature. When a rock is burried the weight of the overlying material puts a pressure on the rock that acts in all direction and confines it.
What is the deformation caused by stress?
Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress. Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress.
What causes faults to move?
Tensional stress is when rock slabs are pulled apart from each other, causing normal faults. With normal faults, the hanging wall slips downward relative to the footwall. These rocks move like your hands do when you rub them together to warm up. The movement along faults is what causes earthquakes.
Compression squeezes rocks together, causing rocks to fold or fracture. Compression is the most common stress at convergent plate boundaries. Rocks that are pulled apart are under tension. When forces are parallel but moving in opposite directions, the stress is called shear.
Can divergent boundaries cause volcanoes?
Most volcanoes form at the boundaries of Earth’s tectonic plates. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. Divergent Plate Boundaries. At a divergent boundary, tectonic plates move apart from one another.
