What types of forces or stresses produces folds in rocks?
Folds in rocks are mainly produced by compressional forces, such as when tectonic plates collide or when rocks are subjected to intense pressure from overlying materials. These forces cause the rocks to deform and bend, resulting in folds. Other factors like temperature, time, and rock composition can also affect the formation of folds in rocks.
What is the difference between the forces that could explain fault block mountains and the forces that could account for an orogeny?
Fault block mountains are formed by the uplifting and tilting of large blocks of the Earth's crust along fault lines, usually due to tensional forces pulling the blocks apart. Orogeny, on the other hand, refers to the process of mountain building typically caused by the collision of tectonic plates, resulting in the folding, faulting, and uplifting of rock layers. The forces generating orogeny are compressional, as opposed to the tensional forces that create fault block mountains.
Tensional forces normally cause what?
Tensional forces typically cause an object to stretch or elongate. These forces act in opposite directions along an object and can result in deformation or breakage if they exceed the object's strength.
What are the 3 internal forces in the earth?
The three internal forces in the Earth are mantle convection, gravity, and radioactive decay. Mantle convection drives the movement of tectonic plates, gravity affects mass distribution and generates stress in the crust, and radioactive decay produces heat that contributes to the Earth's internal energy.
These mountains form from compression.?

Are reverse faults rock layers placed under tensional stress?
No, reverse faults occur in response to compressional stress, not tensional stress. In a reverse fault, the hanging wall moves up relative to the footwall due to compression forces pushing the rocks together.
The major forces that form folded mountains are?
The major forces that form folded mountains are tectonic plate movements, specifically convergent boundaries where two plates collide. The immense compressional forces generated during this collision cause the Earth's crust to buckle and fold, leading to the formation of mountain ranges. Over millions of years, continued plate movements can further deform and uplift these folded mountains.
What force of deformation produces each fault?
A normal fault results from tensional forces pulling rocks apart, causing the hanging wall to move downward relative to the footwall. A reverse fault is caused by compressional forces pushing rocks together, resulting in the hanging wall moving up relative to the footwall. A strike-slip fault is produced by horizontal shearing forces causing rocks to move horizontally past each other.
How are convergert plates different from divergent plates?
Convergent plates move towards each other, causing alot of compressional forces. Divergent plates move away from each other causing alot of tensional forces.
How are folded mountains produced?
Folded mountains form when two plates move towards each other by compressional forces. The movement results in sedimentary rocks moving upwards to form a series of folds.
Tensional forces normally cause which one of the following?
Tensional forces typically cause objects to stretch or elongate.
Is a A normal fault is the result of compressional stress?
No, a normal fault is the result of extensional stress, where the hanging wall moves down relative to the footwall due to tensional forces pulling the crust apart. Compressional stress typically results in reverse faults, where the hanging wall moves up relative to the footwall due to compression forces pushing the crust together.
What 3 types of forces cause folding in rocks?
The three types of forces that cause folding in rocks are compressional forces (pushing together), shear forces (side-by-side movement in opposite directions), and tensional forces (pulling apart). These forces can act on rocks over long periods of time, leading to the deformation and folding of the rock layers.
How are tensional forces created and what role do they play in the mechanics of structures?
Tensional forces are created when a structure is pulled or stretched in opposite directions. These forces play a crucial role in the mechanics of structures by helping to distribute loads and maintain stability. In essence, tensional forces help to counteract compressive forces and prevent the structure from collapsing under pressure.
What force is present in a convergent boundry?
The type of forces that dominate at convergent plate margins are compressive forces. The tensional forces are tectonic forces that tend to push two sides of body in opposite directions so that they slide horizontally past one another.

Fault block mountains are formed by the uplifting and tilting of large blocks of the Earth's crust along fault lines, usually due to tensional forces pulling the blocks apart.
