Worked Solution & Example Answer:DUIN-REHABILITASIE BY TABLE VIEW-STRAND GAAN IN JULIE BEGIN Die stad plan om die duinestelsel langs Table View-strand te rehabiliteer - English General - NSC Marine Sciences - Question 3 - 2023 - Paper 1
Step 1
Noem TWEE toestande wat duinvorming bevorder.
Answer
-
Abundance of sediment: A plentiful amount of sand is essential for dune formation, as it provides the material needed for the dunes to develop.
-
Onshore wind: Winds blowing from the ocean towards the shore help to transport sand and form dunes by moving sediment from one area to another.
Step 2
(a) Beskryf TWEE types natuurlike beweging van waaisand (wind-blow sand) wat ondervind kan word.
Answer
-
Surface creep: This is the movement of sand along the ground, particularly heavy particles that are rolled along the surface.
-
Saltation: This involves the lifting of sand particles a short distance into the air before they fall back to the ground due to gravity.
Step 3
(b) Waarom word dit noodsaaklik beskou om die windverwaaidse sediment te stabiliseer?
Answer
Stabilizing windblown sediment is crucial as it helps prevent erosion and maintains the integrity of coastal ecosystems. By doing so, it protects infrastructure from being damaged by shifting sands and reduces the risk of habitat loss for various species.
Step 4
3.1.3 Die artikel verskaf 'n duidelike voorbeeld van die mens se bestuur van 'n kuslyn.
Answer
-
Watter ingenieursbenadering word in die artikel toegepas?: The article discusses soft engineering approaches to manage coastal erosion effectively.
-
Verskaf bewys uit die teks om jou antwoord te ondersteun.: The text highlights the use of techniques such as dune restoration and the installation of wind nets to stabilize the sand and prevent further erosion.
Step 5
3.1.4 Is die voorstel deur die onderburgemeester goed of swak? Verduidelik jou antwoord.
Answer
Die voorstel is goed aangesien dit 'n holistiese benadering bied om die duinestelsel te rehabiliteer, wat die ekosisteem kan stabiliseer en die infrastruktuur kan beskerm. Dit respekteer die natuurlike prosesse terwyl dit ook mense betrek in die rehabilitasieproses.
