Document Summary
How do submarine canyons affect sediment supply along collision. Submarine canyons are formed by the pull of sediment downward by gravity; the sand (the abrading agent) that the water carries will carve through the surface of land. Once sediment gets into the canyon and is transported to deep sedimentary basins. Continental shelf width affects the proximity that a submarine canyon has to the coastline. Narrow shelf: submarine canyon is closer to shore. Wide shelf: submarine canyon is further from shore. The opposite side of an amero-trailing edge coast is a collision coastline. Barrier island chains, broad sediment-filled lagoons, marsh systems, tidal flats, and river deltas. Ex: entire east coast of the u. s. south of glaciated new. - the size of the rivers discharging along the coast, which is a function of climatic factors (rainfall, weak rocks and erosion) and drainage basin size (controlled by the tectonic history of the continent).
