The continual washing away of the less resistant rock begins to form weak areas on either side of the headlands.
<h3>What are Headlands?</h3>
This refers to the narrow piece of land that is a coastal landform that extends onto a body of water.
Hence, we can see that when headlands occur, there is the coming together of both hard and soft rocks and when this happens, there is the washing away of the less resistant rock that begins to form weak areas on either side of the headlands.

Answer:
geomagnetic field.
Explanation:
The earth magnetic field can be likened to a bar magnet with a North and South pole. It originates from the movement of molten iron and nickel in the outer core.
At every point in time, the magnetic field orientation can change. We must note that the magnetic north lies close to that of geographic north axis of the earth.
Around the mid-oceanic ridges, new materials are brought to the surface. These new materials can contain magnetic minerals such as haematite which are capable of being magnetized as a result of the prevalent magnetic field of the earth. As different materials are brought up, the magnetic minerals preserves the details of the magnetic field at that point in time. Using this information can know the orientation of the magnetic field at any point in time if the magnetic history chart of the earth is constructed. Oceanic ridges becomes older as they move away from the divergent margins.
Turn around and look behind them.
