Document Summary
Terrestrial and oceanic processes converge to produce landscapes that can change rapidly. Many coasts are influenced by plate tectonics: the east coast of north america and the canadian arctic are located on passive margins. Wide continental shelves with barrier islands and sandy beaches: the west coast of north america is located on an active margin. Close to convergent and transform plate boundaries. Coastal hazards include: strong coastal currents, coastal erosion, sea-level rise, storm surges, tsunamis. Wind blowing over the ocean or a lake transfers some of its energy to the water, producing waves. The size of a wave depends on: velocity of wind speed, duration of the wind, fetch (distance the wind blows across water) Waved become organized into groups as they move away from their source: rouge waves are exceptions to these groups. Wave height: distance between the trough and the crest of a wave. Wavelength: distance between successive wave crests.
