How the Crust is Deformed


Predict isostatic adjustments that will result from changes in the thickness predict the earth’s crust and the way it forms. Isostasy is the balancing of two forces. As these isostatic adjustments occur,areas of the are bent up and down and pressure created by this bending causes the rocks in that area of the crust are bent up and down which is why we say that thickness of the earth’s crust predict isostasy. Compression,is when crustal rocks are squeezed together compression often reduces the column of the rocks.Tension,the force that pulls rocks apart from each other,when they pull apart from tension they become thinner.Shearing,rocks pushing in opposite horizontal directions,sheared rock bend,twist,or break apart when they slide past one another.
