Column A Column B 1 Mohs hardness scale A describes the mineral reaction to. What is stress? What number would be given to the hardest? This project will investigate the effects of stress on solid state reactions using analogues to mantle minerals, which can be studied more readily in experiments. E. repeating pattern in minerals in solid? Muscle tension is a typical reaction to stress because it is your body's defense against injury. Sectile - Sectile minerals can be separated with a knife, much like wax but usually not as soft. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and plagioclase feldspar. Mineralogists use terms including tenacity, hardness, cleavage, and fracture to describe mineral strength and how minerals break when stress is applied. The resulting kinetic rate is positive for mineral . According to the model of the General Adaptation Syndrome, the adaptive response that human beings have to stress is developed in three distinct phases: 1- The alarm phase Our first reaction to stress is to recognize the existence of danger and to prepare to deal with the threat, a reaction known as the"fight or flight response."
