A prime example of tensional stress is the mid-Atlantic ridge , where the plates carrying North and South America are moving west, while the plates carrying Africa and Eurasia are moving east. Tensional stress can also occur well within an existing plate, if an existing plate begins to split itself into two pieces.
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 is the real life example of tensional stress Brainly?
Several real life example of tension forces are:
Pulling on a rope in a tug of war game . A car towing another car with the help of a chain . Pulling a rope on a well which is connected to a pulley .
What is formed in tensional stress?
When tensional stresses pull crust apart, it breaks into blocks that slide up and drop down along normal faults . The result is alternating mountains and valleys, known as a basin-and-range. Tectonic Forces.
What is the movement of tensional stress?
Compressive stress happens at convergent plate boundaries where two plates move toward each other. 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 is a real life example of bending?
For example, a closet rod sagging under the weight of clothes on clothes hangers is an example of a beam experiencing bending.
What is a real life example of shear?
Scissors
A pair of scissors is a classic example to demonstrate shear force. When an object, for example, a piece of paper is placed between the two metal blades of a pair of scissors, it gets divided into two parts only because of the shear force.
What are the 3 types of stress?
Common types of stress
There are three main types of stress. These are acute, episodic acute, and chronic stress . We explore each type of stress below.
What are the 3 fault types?
There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip . Figure 1 shows the types of faults that can cause earthquakes. Figures 2 and 3 show the location of large earthquakes over the past few decades.
How can I stop stressing?
- Exercise. Exercise is one of the most important things you can do to combat stress. ...
- Consider supplements. Several supplements promote stress and anxiety reduction. ...
- Light a candle. ...
- Reduce your caffeine intake. ...
- Write it down. ...
- Chew gum. ...
- Spend time with friends and family. ...
- Laugh.
Which type of stress is a uniform?
There are four general types of stress. One type of stress is uniform , which means the force applies equally on all sides of a body of rock. The other three types of stress, tension, compression and shear, are non-uniform, or directed, stresses. All rocks in the earth experience a uniform stress at all times.
What are the types of stress?
- anxiety.
- cardiovascular disease.
- depression.
- high blood pressure.
- a weakened immune system.
What type of stress is compressional stress?
| Type of Stress Associated Plate Boundary type (see Ch. 2) Resulting Strain | Tensional divergent Stretching and thinning | Compressional convergent Shortening and thickening | Shear transform Tearing |

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.
Which type of stress tends to press the rocks towards each other?
Compression is a directed (non-uniform) stress that pushes rocks together. The compressional forces push towards each other.
What causes stress on tectonic plates?
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. Rocks under tension lengthen or break apart.
