scientific study of the deformation of the rocks that make up the Earth’s crust and the forces that produce such deformation. It deals with the folding and faulting associated with mountain building; the large-scale, gradual upward and downward movements of the crust (epeirogenic movements); and sudden horizontal displacements along fau...
tectonism (geology)
large-scale deformation of Earth’s crust by natural processes, which leads to the formation of continents and ocean basins, mountain systems, plateaus, rift valleys, and o...
tectorial membrane (anatomy)
...the base and low tones vibrate the region near the apex. Sitting on the basilar membrane is the organ of Corti, an array of hair cells with stereocilia that contact a gelatinous membrane called the tectorial membrane. Sound entering the inner ear stimulates different regions of the basilar membrane, depending on sound frequency. Hair cells in the stimulated regions are excited by the resulting....
