The 4 types of erosional processes are Hydraulic action, Abrasion, Attrition, Corrosion. Hydraulic action is the explosion of compressed air trapped in cracks and crevasses of cliffs by advancing waves. Abrasion occurs when rock particles are hurled by the waves against cliff surfaces. Attrition is the breakdown of rock particles as they his cliff faces and each other. Corrosion is the chemical decomposition of rocks by sea water and is most effective on limestone rocks. All erosional patterns work together at the same time to form a crack (fist signs of erosion or weakness) then cave, arch, stack and finally stump all of which are the steps to a gradually reduced headland for example Port Campbell. The erosional process in some cases can erode rocks very fast in coastal regions.

How does a headland change over time?
The headland, if it overhangs a body of water, can collapse in much less the 250 years. If can in fact change over the course of a single day.
How did the headland change in 250 years?
Headlands can change over time due to various factors such as erosion from wind and water, tectonic activity, and sea level rise. In 250 years, a headland could erode significantly, resulting in a change in its shape and size. Vegetation and human activities can also impact the stability and appearance of a headland over time.
Why do waves expend so much energy on a rocky headland?
When waves approach a rocky headland, they are forced to change direction and refract around the obstacles. This change in direction causes an increase in wave energy and pressure on the headland, resulting in erosion and the release of energy as the waves crash against the rocks. The energy is dissipated as the waves break, causing erosion and shaping the coastline over time.
How does a headland turn into a stump over time?
A headland turns into a stump through the process of coastal erosion. As waves continually hit the headland, they erode the softer rock and sediment around it, leading to the formation of caves, arches, and eventually, the collapse of the headland. Over time, the landmass becomes smaller and more isolated, resulting in a stump, which is a remnant of the original headland left standing in the water. This transformation is driven by persistent wave action and weathering processes.
What is a headland deposition or erosion?
A headland is a narrow strip of land that extends out into a body of water, such as an ocean or lake. Deposition at a headland occurs when sediment is deposited at the end of the headland due to wave energy decreasing and the current losing its ability to carry sediment. Erosion at a headland happens when waves and currents wear away the land, shaping the headland over time.
What occurs when waves approach a headland and bend around it?
As waves approach a headland, they refract or bend around it due to a change in water depth. This causes the side of the headland facing the waves to experience erosion, while the side sheltered from the waves may experience deposition. Over time, this process can result in the formation of distinctive coastal features like sea caves and arches.
How is a headland made by?
A headland is formed by erosion and weathering along the coast. The softer rock and sediment of the coastline are eroded more quickly than the harder rock, creating a protruding landform. Over time, the continuous erosion and deposition processes shape the headland.
What effect do waves have on a headland?
Waves can erode a headland through processes such as abrasion (scouring by sediment in waves), hydraulic action (force of water against rock), and corrosion. These processes can lead to the formation of features like caves, arches, and stacks on the headland. Over time, the headland may be reshaped or even reduced in size due to wave action.
When waves cut completly through a headland what is formed?
When waves cut completely through a headland, a feature called a sea cave is formed. Sea caves are formed by the relentless erosion of waves gradually wearing away the weaker rock layers of a headland. Over time, the waves create openings and cavities that can extend deep into the headland.
How does spit form on a rocy headland?
Spit formation on a rocky headland occurs through a combination of wave action and sediment transport. As waves approach the coastline, they carry sediment and erode the land, depositing material in a process known as longshore drift. When the prevailing currents encounter a change in the coastline, such as a rocky headland, the sediment accumulates, gradually extending outwards to form a spit. Over time, the spit can grow as more sediment is deposited, creating a landform that extends into the water.
