Document Summary
Introduction to coastal hazards: terrestrial and oceanic processes converge to produce landscapes that can change rapidly, many coasts are influenced by plate tectonics. East coast of north america and the canadian artic are located on passive margins: wide continental shelves with barrier islands and sandy beaches, no subduction happening, large sandy beaches. Many coasts in canada are affected by seasonal ice. Coasts in temperate regions may have dense marshes. Tropical coasts may contain mangroves and coral reefs: coastal hazards include: Sea-level rise: related to storm surges. Tsunamis: wind blowing over the ocean or a lake transfers some of its energy to the water, producing waves, size of wave depends on: Coastal processes: velocity of the wind, duration of the wind, gusty or continuously blooding. 3: distance the wind blows across the water, waves become organized into groups as they move away from their source.
