compression,tension,and shear
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.
Principal stresses are those stresses that act on principal surface. principal surface here means the surface where components of shear-stress is zero.
There are three main forces that drive deformation within the Earth. These forces create stress, and they act to change the shape and/or volume of a material. The following diagrams show the three main types of stress: compressional, tensional, and shear. Stress causes the build up of strain, which causes the deformation of rocks and the Earth's crust. Compressional stresses cause a rock to shorten. Tensional stresses cause a rock to elongate, or pull apart. Shearstresses causes rocks to slip past each other.
Compression, tension, and shearing are all types of mechanical stresses that occur in materials. Compression involves forces that act to compress or shorten the material, while tension involves forces that act to stretch or elongate the material. Shearing involves forces that act parallel to a surface, causing sliding or distortion of material layers. All three types of stress can cause deformation or failure in materials if they exceed the material's strength.
the plane in which three mutually perpendicular stresses act and the resultant of all is purely normal stress . in this plane value of shear stress is zero

Crude oil is found in sedimentary rocks, particularly in sandstone and limestone formations. These rocks act as reservoirs for the oil, trapping it within their porous structures. Oil exploration typically targets these types of rocks for potential hydrocarbon deposits.
Sandstone and limestone are commonly considered as reservoir rocks for hydrocarbons. These rocks have high porosity and permeability, allowing them to hold and transmit oil and gas. Other sedimentary rocks like shale can also act as reservoirs under certain conditions.
Denial is the act of asserting that a particluar allegation or fact is not true. There are three different forms or types of denial, including: projection, simple denial, and minimisation.
They need to study how stresses and other forces will act in structures and trigonometry is essential for studying these.
Some types of selection pressures that could act on a population of an animal species are searching for food, searching for water, and finding a mate. Other pressure could be avoiding predators and finding shelter.
