What are the three main components of a sediment cell?
The sediment cell concept (sources, transfers and sinks) is important in understanding the coast as a system with both positive and negative feedback, it is an example of dynamic equilibrium..
How do coasts operate as a system?
The Coastal System The coast is as an open system as it receives inputs from outside the system and transfers outputs away from the coast and into other systems. These systems may be terrestrial, atmospheric or oceanicand can include the rock, water and carbon cycles.
Why are coastlines important?
Because coasts are dynamic, or constantly changing, they are important ecosystems. They provide unique homes for marine plants, animals, and insects. … Coasts help us understand natural events, such as weather and changing sea levels.
What are high energy coasts?
High-energy coasts are those that are exposed to strong, steady, zonal winds and fronts with high wave energies in the lee of highlatitude storm waves and low latitude swells (Davies, 1973), unprotected by shallow offshore topography, and receive the highest energy.
How was the Holderness coast formed?
Geology. Underlying the Holderness Coast is bedrock made up of Cretaceous Chalk. … The first is the result of the strong prevailing winds creating longshore drift that moves material south along the coastline. The second is that the cliffs are made of soft boulder clay which erodes rapidly when saturated.
How are wave cut platforms formed?
A wave-cut platform is formed when the following occurs: The sea attacks the base of the cliff between the high and low water mark. 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. … The cliff continues to retreat.
What are the features of a coast?
Coasts have many different features, such as caves and cliffs, beaches and mudflats. Tides, waves, and water currents (flow) shape the land to form these coastal features. Some coasts are also changed by the flow of glaciers, which are huge rivers of ice, and lava from volcanoes.
What is a coastal landscape system?
A coastal landscape is a section of coastline that has a range of coastal features; some erosional, some depositional. It is distinguishable from neighbouring coastal landscapes by prevailing characteristics that dominate the form of the coastline there. … The input of energy and sediment into the coastal zone.
What type of system is the coast?
open systemCoasts are considered an example of an open system as they have inputs and outputs.
What is a natural system geography?
These are systems that occur in nature, and together they form the ecosystems that make up our natural environment. – Circulation of Water in our ocean. – Weather and Climate Systems. – Energy Cycles. – Food Chain.
Are coasts open systems?
The Coastal System Coastal landscapes are open systems. This means energy and matter can enter and leave the system.
What are low energy coasts?
Low-energy coasts are coasts sheltered from storms and swells by adjacent topographical features (barrier island, reef, embayment, shoal, headland), by their position with respect to prevailing wind direction, by their position in a climatic belt, by gentle offshore topography, or by a combination of these factors.
