INDIAN GEOGRAPHY

Detailed explanation-1: -Tensional stress involves forces pulling in opposite directions, which results in strain that stretches and thins rock. Compressional stress involves forces pushing together, and compressional strain shows up as rock folding and thickening.

Detailed explanation-2: -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.

Detailed explanation-3: -Anticlines and synclines are examples of structures caused by compression. Folds like these form from compression. This anticline (up-fold) and syncline (down-fold) are in limestones in the Valley and Ridge of Giles County. Lateral shear stress pushes rocks horizontally past each other in two opposite directions.

Detailed explanation-4: -Compressive stress is the force that is responsible for the deformation of the material such that the volume of the material reduces. It is the stress experienced by a material which leads to a smaller volume. High compressive stress leads to failure of the material due to tension.

Detailed explanation-5: -10.6a: Compressive forces generate folding and faulting as a consequence of shortening. Compressive forces are common along convergent plate boundaries resulting in mountain ranges. (b) Fig. 10.6b: Tensional forces cause stretching and thinning of the rocks, usually accompanied by tensional faults.
