What kind of physical quantity is stress which kind of stress is most likely to cause an earthquake?
stress is an immense force exerted inside a material, there are different types of stress such as compression, tension, and shear stress, shear stress is most likely to cause an earthquake.
What are two ways that stress in rock can be relieved?
A rock can be relieved of stress by breaking, compressing, bending, or stretching. What properties of rocks could contribute to a serious earthquake?
What physical property of rocks along a fault zone allows earthquakes to occur?
The elastic rebound theory suggests that if slippage along a fault is hindered such that elastic strain energy builds up in the deforming rocks on either side of the fault, when the slippage does occur, the energy released causes an earthquake.
What are two angular measurements that describe the orientation of a fault?
Two angular parameters are required to describe the orientation of the fault plane, (i) strike of the fault, ϕ i.e. the azimuth of the fault’s projection onto the surface measured from the north and (ii) the dip of the fault, δ i.e. the angle measured downward from the surface to the fault plane in the vertical plane …
What type of stress causes the formation of mountains?
The force of compression can push rocks together or cause the edges of each plate colliding to rise. Mountains are a result of high-impact compression stress caused when two plates collided.
What type of stress occurs at a divergent plate boundary?
Tension
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.
How rocks behave under different types of stress?
Rocks have three possible responses to increasing stress (illustrated in Figure below): elastic deformation: the rock returns to its original shape when the stress is removed. plastic deformation: the rock does not return to its original shape when the stress is removed. fracture: the rock breaks.
How do rocks behave under compression stress?
Rocks deforming plastically under compressive stresses crumple into folds (Figure below). They do not return to their original shape. If the rocks experience more stress, they may undergo more folding or even fracture.
What is the difference between a footwall and hanging wall?
The hanging wall is the block of rock above the fault line. The footwall is the block of rock below the fault line. You can walk on it as if it were the floor below you.
What is stress and how is It measured?
Thus, Stress is defined as “The restoring force per unit area of the material”. It is a tensor quantity. Denoted by Greek letter σ. Measured using Pascal or N/m2. Mathematically expressed as – F is the restoring force measured in Newton or N. A is the area of cross-section measured in m2. Stress can be expressed using multiple units.
What are the normal stresses on the surface?
Illustration of typical stresses (arrows) across various surface elements on the boundary of a particle (sphere), in a homogeneous material under uniform (but not isotropic) triaxial stress. The normal stresses on the principal axes are +5, +2, and −3 units.
What are the different types of stress in physics?
There is various type of stress in physics but mainly it is categorized into three forms : 1. Normal Stress 2. Tangential Stress or Shearing Stress 3. Hydraulic stress Stress that occurs when a member is loaded by an axial force is known as normal force. In other words, when, the stress applied is perpendicular to the body.
What is the difference between force and stress?
Stress is a physical quantity that defines the internal force. The stress is specifying as the force across a “small” boundary per unit area of that boundary. Stress is a fundamental quantity, like velocity, torque (energy). A one question strike in your mind which thing you can stress and which are not.
