ESCI 1001 Lecture Notes - Lecture 11: Surf Zone, Tide, Earth Radius
Document Summary
Of antarctica is covered with land. But plate tectonic does make a difference in shorelines. West coast parallels active plate boundary: steep slopes, narrow to no beach, no barrier island. East coast is passive continental margin: gentle slopes, wide extensive beaches, barrier island. Waves are not waves in geology- its surf. Sea level isn"t always the same- low and high tide: tides are different between winter and summer, times of day. Ocean and coastline systems: both are very dynamic systems that affect humans. Main human interactions: short term/regional- coastline system, long term/global- ocean current system. Coastline systems: coastlines are dynamic systems that changes on a variety of timescales, most erosion, transport and deposition of sediment in the oceans occur along coastlines in the surf zone, coastal processes respond in predictable manners. R= distance between 2 bodies (center to center) r= satellite radius. Between earth and moon, r, m, and m are constant.
