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.
The 3 external forces acting on Earth are gravity from the Sun and Moon, solar radiation pressure, and tidal forces from the Moon and Sun.
Earthquakes are internal forces of change caused by tectonic plate movement and stress release along faults within the Earth's crust. They are not considered external forces as they originate from within the Earth.
Monoclines are usually caused by tectonic stress, where compressional forces create a bend or flex in the Earth's crust. The stress may result from processes such as faulting, folding, or uplifting.
The three main rock stresses are compressive stress (pushing forces that reduce rock volume), tensile stress (pulling forces that stretch rock), and shear stress (parallel forces that cause rocks to slide past each other). These stresses can lead to different types of rock deformation and failure.

Stress in the Earth's crust is caused by tectonic forces like plate movements, which create pressure along faults and boundaries where plates meet. This stress can build up over time and be released in the form of earthquakes when the rocks along these fault lines break.

compression stress
Tectonic stress, caused by the movement of Earth's tectonic plates, produces the most significant crustal deformation. This stress results in the formation of features like mountains, faults, and earthquakes as the Earth's crust responds to the forces generated by tectonic plate interactions.
Stress is the force per area, which has the same units as pressure. An elastic material's response to stress is called the strain which is the change in its dimensions divided by its original dimension, such as a change in length divided by length, or change in volume divided by volume. It is a fundamental law that the stress is proportional to the strain, with the proportionality constant being the elastic modulus of the material, Young's modulus for change in length or the the compressibility for change in volume. For shear forces, the modulus is called the shear modulus and the strain is the deformation in the direction of the force divided by the distance from the fixed base that the forces is exerted.
The three types of stress that occur in Earth's crust are compressional stress (pushing together), tensional stress (pulling apart), and shear stress (parallel sliding in opposite directions).
That type of stress is known as tensile stress. It occurs when forces are applied to an object in such a way that they tend to elongate or stretch the object.
