For example, you wrote, "well plate tectonics form mountains,volcanoes. so plate tectonics affects sedimentation by using it to build up the mountains or volcanoes. also it my affect by making it sediment alot. and also the question means how does the forming of plate tectonic affect sedimentation.
a theory of global tectonics in which the lithosphere is divided into a number of crustal plates, each of which moves on the plastic asthenosphere more or less independently to collide with, slide under, or move past adjacent plates."
