NettetTypes of Stress. Stresses fall into two categories: normal stress acts at right angles to a surface, and shear stress acts parallel to a surface (Figure 13.2). Normal stress is subdivided into compression, when the stresses are squeezing a rock, and tension, when stress is pulling it apart. Rocks undergo compression in regions where plates are ...

Nettet16. sep. 2013 · Making the space is no problem – the magma can simply push the surface up. Satellite imaging of volcanoes often shows the surface rising up and down as magma moves about so no problem here. Large areas of granite are more common at greater depth. If there is 10km of rock above, it is not obvious how the magma could push the … NettetDifferent processes can deform rocks, the deformation is almost always the result of stress. This stress leads to the formation of fault and fold structures, both can either extend or shorten of the Earth's crust. Thick-skinned deformation specifically affects deep crystalline rock of the basement and may extend deeper into the lower crust. giratina and the sky warrior pokeflix
