WebMar 19, 2016 · The mantle viscosity is likely to be non-linear, e.g., it could be as low as 10 18 Pa ⋅ s (over shorter time scales) or as high as 10 21 Pa ⋅ s (over longer time scales). In any case the values reported in the literature are somewhere between 10 18 − 10 21 Pa ⋅ s and these are based on studies from earthquakes, glacial rebound etc. WebSuch stresses can be induced by cooling of rock (volume decreases as temperature decreases) or by relief of pressure as rock is eroded above thus removing weight. Joints provide pathways for water and thus pathways for chemical weathering attack on rocks. If new minerals are precipitated from water flowing in the joints, this will form a vein. can email account be hacked

WebMar 31, 2024 · Plate movement is possible because the lithosphere-asthenosphere boundary is a zone of detachment. As the lithospheric plates move across Earth’s surface, driven by forces as yet not fully understood, they interact along their boundaries, diverging, converging, or slipping past each other. http://earthguide.ucsd.edu/eoc/teachers/t_tectonics/p_layers.html WebDec 22, 2024 · In terms of time scale, attenuation bridges the short-term elastic and long-term viscous responses of rocks to an applied stress, and the mechanisms causing attenuation are closely related to those that allow viscous deformation in … fis sis
