    • 3. 2.Erosion process Formation of Cliffs and of weaknesses (A) attacks lines Wave cut platforms3.Notch ( narrow pass/cut) will be deepened to produce a cave4. Undercutting of the cave results in an overhanging cliff (B)5.Overhanging cliff may collapse (C)6. Cliff retreats further inland with 3

    • 5. 2.The less resistant rocks will be Formation of Headlands and Bays eroded faster than the more resistant hard rocks. (A)3.When the softer rocks are eroded away, bays are formed.4.The remaining hard rocks extending into the sea are known as headlands. (B) 5

    • 7. describe a the1.Waves reach the coast at an oblique angle creates longshore current process of2.The materials move in a zigzag pattern in a down drift direction ( beach drift) longshore3.The swash carries materials up the beach at the same angle as when the wave approaches the shore driftbackwash and any4.As the swash dies away, the [4] materials carries by it return straight down the beach at right angles to the water line due to gravity.5.Longshore drift = beach drift + longshore current 7
    • 8. The process by which waves are been or turned from its origin 3 Wave refraction1. Waves usually approach coast at an angle2. But when it hits the headlands, the energy is concentrated and erodes the headlands3. The energy is spread out as it moves towards the 2 bay. Results in deposition 1 of sentiments at the bay- 8 forms beaches.
