What happened to the water particles in a wave?
Answer: waves transport energy, not water. As a wave crest passes, the water particles move in circular paths. The movement of the floating inner tube is simulacra to the movement of the water particles. Water particles rise as a wave crest approaches.
Where are destructive waves found?
What are destructive waves? Destructive waves are usually found in more exposed bays, where they build pebble beaches. Although a destructive wave’s swash is much stronger than that of a constructive wave, its swash is much weaker than its backwash.
What are the 4 erosion processes?
The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks.
How does Cliff collapse occur?
Cliffs are shaped through erosion and weathering . A wave-cut notch is formed by erosional processes such as abrasion and hydraulic action – this is a dent in the cliff usually at the level of high tide. As the notch increases in size, the cliff becomes unstable and collapses, leading to the retreat of the cliff face.
What happens once the overhanging cliff has collapsed?
Erosional landform: The overhang will collapse and the cliff will retreat. This will create a wave-‐cut platform which is visible during low tide and submerged during high tide.
What is Cliff failure?
The material moves down slope along a curved surface, leaving behind an exposed scarp face below the head of the slump, and producing a hummocky toe at the foot. Rock falls. Here, large and small fragments of rock are continually weathered and eroded until they separate and fall from the cliff as whole parts.
How is cliff erosion affected by dip?
The angle the beds dip at affects how they are eroded and the profile of the resulting cliffs. Beds that dip seaward produce gentler cliffs but are less stable because loose material can slide down the bedding planes in mass movements. Landward dipping beds produce stabler & steeper cliffs.
