Coastal landscapes: Practice Questions

• a.D: Chemical weathering → rock falls onto the beach → waves roll rocks back and forth → sand is created.
• b.B: Strong tides → waves hit coast head-on → sediment moves in a circular motion → deposition in deep water.
• c.C: High energy waves → abrasion of cliffs → sediment falls to the base → longshore drift carries it offshore.
• d.A: Prevailing wind → waves hit coast at an angle → swash moves sediment up at an angle → backwash moves it straight down.

• a.B: The loss of agricultural land or residential property to the encroaching sea.
• b.C: The disruption of longshore drift which increases erosion at the next headland.
• c.A: The high cost of importing granite boulders for rock armour.
• d.D: The visual pollution caused by large concrete structures on the beach.

• a.C: Waves lose energy as they enter deep water, causing sediment to build up into headlands.
• b.B: Bands of resistant and less resistant rock run perpendicular to the coast, leading to differential erosion.
• c.D: Vegetation on the dunes protects certain areas of the coast, while others are eroded into bays.
• d.A: Different rock types are arranged in layers parallel to the coast, leading to uniform erosion.
