WebKey idea ⮕ Coastal landscapes can be viewed as systems. When a system's inputs and outputs are equal, a state of equilibrium exists within it. In a coastal landscape, this could happen when the rate at which sediment is being added to a beach equals the rate at which sediment is being removed from the beach; the beach will therefore remain ...

The meltwater will force air into fissures in the bed and banks of the channel resulting in pressure cavitation, causing material to be loosened. WebDue to the different nature of rock erosion occurs at different rates. Less resistant rock (e.g. boulder clay) erodes more rapidly than more resistant rock (e.g. chalk). A discordant coastline before erosion occurs The bands of soft rock, such as sand and clay, erode more quickly than those of more resistant rock, such as chalk. lactated ringers coding
