Earth Science PT#2:”Rock Stress Model” “HOW ROCKS UNDERGO STRESS” Submitted by: Niere , Jude Michael Submitted to: Mrs. Mary Joy Verba 11 STEM-FELDSPAR.

What is “STRESS” - Stress is a force that is applied to a rock and can result in fracture/deformation . The three major forms of stress are usual . Compression at convergent plate borders, tension at divergent plate boundaries, and shear at transform plate boundaries are the three types of plate boundaries. Rocks fold as they deform plastically ..

There are 3 types of stresses that rocks commonly undergo. -Compressional Stress -Tensional Stress -Shear Stress.

Jude Michael @ judeeemichael. 1. Compressional Stress -The stress that squeezes something. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock..

Jude Michael @ judeeemichael. 2. Tensional Stress -Something is squeezed as a result of the pressure. It is the stress component perpendicular to a particular surface, such as a fault plane, caused by forces applied perpendicular to the surface or distant forces communicated through the surrounding rock..

Jude Michael @ judeeemichael. 3 . Shear Stress -Force that tends to generate material deformation due to slippage along a plane or planes parallel to the imposed tension. Shear as a result of is extremely important in nature, since it is intricately tied to the movement of earth elements downslope and earthquakes..
