What are the outputs in a coastal system?
Landforms, sediment and the shape of the coastline are all outputs. Erosion, deposition, transportation (longshore drift) all take place along the coast.
What are the three main components of the coastal system?
The three main components of the coastal system are:
- the underlying geology such as coastal headlands and near shore islands;
- the nature and abundance of the coastal sediment; and.
- the extent to which these controls are acted on by the waves and wind.
What are the key elements of a coastal system?
The Coastal System
- Coastal Inputs. Marine – waves, tides and currents.
- Coastal Transfers. Stores such as sediment on a beach, and flows (transfers), such as longshore drift moving sediment along the coast.
- Coastal Processes. Deposition.
- Coastal Outputs. Marine and wind erosion as well as evaporation.
- System feedback.
What are the 4 coastal processes?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition.
What are inputs and outputs in geography?
Inputs are thing things needed to produce something. Processes are the activities done to to the inputs make something new or different. Outputs are the results of the processing, usually a new product.
Where are coasts located?
The coast is the land along a sea. The boundary of a coast, where land meets water, is called the coastline. Waves, tides, and currents help create coastlines. When waves crash onto shore, they wear away at, or erode, the land.
How is the coastal system linked to other natural systems?
As an open system the coast is linked to other natural systems, including the atmosphere with wind energy as an input of energy. Sediments eroded from the coast transported into deep oceans become part of geological systems, with dissolved carbon from chalk and limestone cliffs moving through the carbon cycle.
What are the main inputs of energy in a coastal system?
Three sources of energy drive the coastal system: 1 Solar energy 2 Gravitational energy 3 Geothermal energy.
What are 5 types of coastal erosion?
There are five main processes which cause coastal erosion. These are corrasion, abrasion, hydraulic action, attrition and corrosion/solution. Corrasion is when waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff.
What is an output in a system geography?
What are the inputs and outputs of coastal systems?
Coastal systems: inputs, outputs and processes. Terms in this set (14) INPUTS. Energy is inputted in the form of wave energy, wind currents and tides. Material is inputted mostly through processes of erosion and fluvial processes. OUTPUTS. Landforms, sediment and the shape of the coastline are all outputs.
What is a coastal system?
It is a dynamic system of inputs, processes and outputs. Any change to a particular component (whether caused naturally or by human intervention) will have an impact on the rest of the system. For example groundwater, the water cycle and rivers have an impact on the coastal system. This is the area between the land and the sea.
How many sediment cells are there in the coastal system?
Within the English and Welsh coastal system are 11 sediment cells, each one being a theoretically closed system. Owing to the nature of the coast as an open system, it also links to other systems- sediment from rivers joins the coastal system, water is evaporated and joins the atmospheric system etc.
How can the coast be seen as a system?
The coast can be seen as a system in order to help to understand the processes and interactions involved. In theory, the inputs, processes and outputs work together to create coastal equilibrium.
