What type of mountain is this the Basin and Range province is characterized by many normal faults?
The Basin and Range province is characterized by many normal faults. The Cascade Range in the United States has many eruptive mountains.
What type of stress would you expect at convergent plate boundaries?
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.
Which of the following types of stress is equal in all directions?
Pressure is a stress where the forces act equally from all directions. If stress is not equal from all directions then we say that the stress is a differential stress. Three kinds of differential stress occur.
What kind of stress leads to the thinning of Earth’s crust?
In horizontal compression stress, the crust can thicken or shorten. In vertical compression stress, the crust can thin out or break off.
What type of fault is in the Basin and Range Province?
listric normal faulting It is generally accepted that basin and range topography is the result of extension and thinning of the lithosphere, which is composed of crust and upper mantle. Extensional environments like the Basin and Range are characterized by listric normal faulting, or faults that level out with depth.
How were the mountains in the Basin and Range Province formed?
The basins (valleys) and ranges (mountains) are being created by ongoing tension in the region, pulling in an east-west direction. Over most of the last 30 million years, movement of hot mantle beneath the region caused the surface to dome up and then partially collapse under its own weight, as it pulled apart.
What is a compressional stress fault?
The stress that squeezes something. 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 happen in compressional stress?
Compressional stress is when a rock is pressed together into itself, like when crust movements cause two rocks to squeeze another one between them. Another example is when mountains are formed at a convergent boundary, like the Rocky Mountains.
What is the longitudinal stress?
Longitudinal Stress = Deforming Force / Area of cross-section = F/A. As the name suggests, when the body is under longitudinal stress- The deforming force will be acting along the length of the body. Longitudinal stress results in the change in the length of the body. Hence, thereby it affects slight change in diameter …
What is axial compressive stress?
Compressive stress is axial stress that tends to cause a body to become shorter along the direction of applied force. Tensile stress is axial stress that tends to cause a body to become longer along the direction of applied force. Compare shear stress strain.
What does tensional stress cause?
Tensional stresses cause a rock to elongate, or pull apart. Shear stresses causes rocks to slip past each other.
What is shear stress in geology?
Shear stress is the stress component parallel to a given surface, such as a fault plane, that results from forces applied parallel to the surface or from remote forces transmitted through the surrounding rock.
What caused the Basin and Range Province?
The basins (valleys) and ranges (mountains) are being created by ongoing tension in the region, pulling in an east-west direction. Over most of the last 30 million years, movement of hot mantle beneath the region caused the surface to dome up and then partially collapse under its own weight, as it pulled apart.
What is fault-block mountain Range?
Fault-block mountains are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust (Figure 3). Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle (see Figure 1).
What type of mountain is the Basin and Range Province?
The Basin and Range is characterized by northerly to northwesterly-trending narrow, rugged mountain ranges separated by broad basins. This topography results from extension of the Earth's crust.
Which type of stress causes fault block mountains quizlet?
Where two plates move away from each other, tension forces create many normal faults. When two of these normal faults form parallel to each other a block of rock is left lying between them. As the hanging wall of each normal fault slips downward, the block in between moves upward forming a fault-block mountain.
What fault is caused by tension?
normal fault Tensional stress, meaning rocks pulling apart from each other, creates a normal fault. With normal faults, the hanging wall and footwall are pulled apart from each other, and the hanging wall drops down relative to the footwall.
What type of stress causes faults?
The three types of stress that cause faults are compressional stress, shear stress, and tensional stress.
What is hydrostatic stress condition?
In continuum mechanics, hydrostatic stress, also known as volumetric stress, is a component of stress which contains uniaxial stresses, but not shear stresses. A specialized case of hydrostatic stress, contains isotropic compressive stress, which changes only in volume, but not in shape.
What is lateral stress?
Lateral stress is the stress produced in lateral direction. Lateral strain is defined as the ratio of the change in diameter of a circular bar of a material due to deformation in the longitudinal direction.
What is longitudinal stress and compressive stress?
The Longitudinal Stress either stretches the object or compresses the object along its length. Thus, it can be further classified into two types based on the direction of deforming force- Tensile stress. Compressive stress.
What is transverse stress?
Transverse shear stress is the resistance force developed per unit cross-sectional area by an object to avoid transverse deformation. The transverse deformation in the object arises due to the application of bending load.
Which force created a fault block mountain?
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 is shear stress and tensile stress?
The main difference between shear stress and tensile stress is that tensile stress refers to cases where a deforming force is applied at right angles to a surface, whereas shear stress refers to cases where a deforming force is applied parallel to a surface.
What type of fault is Basin and Range Province of North America?
The dominant physiographic structure of the Basin and Range Province is the result of a series of normal fault-blocks, most of which are tilted either to the east or west.
What causes fault-block mountains?
Fault-block mountains are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust (Figure 3). Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle (see Figure 1).
What type of faulting produces fault-block mountains?
rifting Fault-block mountains often result from rifting, an indicator of extensional tectonics. These can be small or form extensive rift valley systems, such as the East African Rift zone. Death Valley in California is a smaller example.
What kind of fault is found in the Basin and Range Province in North America?
listric normal faulting Extensional environments like the Basin and Range are characterized by listric normal faulting, or faults that level out with depth.
What is fault-block mountain range?
Fault-block mountains are formed by the movement of large crustal blocks along faults formed when tensional forces pull apart the crust (Figure 3). Tension is often the result of uplifting part of the crust; it can also be produced by opposite-flowing convection cells in the mantle (see Figure 1).
Which type of fault occurs when rock is subjected to stress?
Tensional stress, meaning rocks pulling apart from each other, creates a normal fault. With normal faults, the hanging wall and footwall are pulled apart from each other, and the hanging wall drops down relative to the footwall.
