1. MARINE AND
COASTAL PROCESSES
AND THEIR EFFECTS

2. CONTENT STANDARDS
•The learners demonstrate an
understanding about the different
hazards caused by coastal processes
(waves, tides, sea-level changes,
crustal movement, and storm surges)

3. PERFORMANCE STANDARDS
•The learners shall be able to:
•Conduct a survey to assess the
possible geologic hazards that
your community may experience.

4. LEARNING COMPETENCY
•Describe how coastal processes result in
coastal erosion, submersion and saltwater
intrusion.
•(S11/12ES-Ih-38)

5. OBJECTIVES
1. Recognize the coastal processes that influence
the coastal landforms and associated hazards.
2. Describe how the coastal processes determine
the present coastal hazards whether coastal
erosion, submersion or saltwater intrusion
3. Understand the ways that will help to lessen
the coastal processes

8. •Coastal – the part of the land
that are near the coast .
•Erosion the process of eroding or
being eroded by wind ,water or
other natural gas

9. COASTAL EROSION
•loss or displacement of land along
the coastline due to action of
waves ,current, tides an, wind-driven
water , waterborne ice ,or other
impacts of storms

10. •wearing away of the land by
the sea and is done by
destructive waves

12. COASTAL PROCESSES
•responsible for some of the most
amazing landforms or coastal
formations in the country and in the
world .

13. •Submersion – Is an act of being
completely held under the water
•Saltwater intrusion-is the movement
of saltwater into underground
sources (aquifers)of fresh water

14. QUESTIONS
•What coastal processes are involved?
•How coastal processes result in coastal
erosion ,submersion and saltwater
intrusion.

17. GROUP ACTIVITY
Group Task
•After reading the case, the group will
identify the anthropogenic factors that
contribute the rapid coastal erosion in the
island using the chart.

18. •First column,list down all possible
causes of coastal erosion.In the second
column,provide a brief explanation
how it contributed to coastal erosion .

19. Anthropogenic
Factors
Role in Coastal
Erosion

20. GUIDE QUESTIONS
1.What specific human activities can be attributed to
coastal erosion in the island ?
2.What should be done to control rapid coastal erosion in
Boracay ?
3.There are plans to limit the number of tourist arrival in
boracay to help the environment recover faster. Is it a
good idea?

21. REFLECTION
•How fast a coastal
erosion occurs ?

22. EVALUATION

23. Identify the correct answer to the
following statement.
1.Wearing away of the land by the sea
and is done by destructive waves

24. 2. It is responsible for some of the
most amazing landforms or coastal
formations in the country and in the
world .
3. An act of being completely held
under the water .

25. 4. The movement of saltwater into
underground sources (aquifers)of fresh
water
5. The process of eroding or being
eroded by wind ,water or other
natural gas

26. ASSIGNMENT
•Picture Do not Lie !
•Are you fond of keeping your old Photos? How would you compare
yourself now with your old pictures? Just like our old pictures I
want you to write your observation about Boracay before and
Boracay today in a short bond paper if there is many changes .
