ACTIVITIESActivity 1: Observation of Coastal LinesCarefully study the two mapspaying particular attention tothe outlines of the continents(for the world map) and for thePhilippines, the outlines of theislands (represents the coastalareas).Describe the coastlines. (e.g.irregular or smooth, etc.). Whydo you think coastlines exhibitsuch forms?Activity 2: Identifying HazardsAfter knowing the different Coastal processes and its effects, show the effects ofcoastal erosion leading to the destruction of houses and other infrastructures alongthe coasts and the steepening of the coastal area. Identify at least three (3)examples of the effects of these coastal processes (preferably site specific areas inthe Philippines).REMEMBERHere’s the key concepts that you must remember on Marine and Coastal Processesand their Effects.I.Different Coastal ProcessesTides– The rise and fall of ocean water under the influence of the gravitationalpull of the moon and sun creates tides.Waves– Ocean waves erode and shape the world’s coastlines because thewater within the wave moves up and down. Ocean waves will not be producedif there is no wind.Strom Surge– This hazard is also described as coastal flood or tsunami-floodphenomenon, happens when there is rising of the sea as a result ofatmospheric pressure variation and having wind associated with a storm. Theseverity of which is affected by the shallowness and orientation of theII.Hazards brought by the different Coastal ProcessesCoastal Erosion.The wearing away of the land by the sea and is done bydestructive wavesSediment movement along coasts. As wave crashes on the shore, the waterpushes sediment up the beach and then pullsback down the beach as thewater slides back down.Coastal deposition. When waves lose their capacity to carry or transportsediments because of a reduction in energy, they can and will "drop" or depositits sediment load.Submersion.It isdescribed when sediment is submersed under water andeventually replaced back to its original location. This often takes place duringviolent storms, when sand is dragged or pushed underwater, and it tends toreturn back to the visible place (via wave action) it had previously been whenthe seas have calmed down.Saltwater intrusion. Is defined as the flow of seawater into fresh water bodieslike rivers or aquifers due to natural processes or human activities.
