Geography Revision Knowledge Test 1

The Coast
The narrow contact zone between land and sea, constantly changing due to land, air and marine processes (an open system).
1 of 8
Inputs -Erosional processes
Energy: waves, wind, tides, currents. Sediment. Geology of coastline. Sea level change.
2 of 8
Components -Wind and water transport
Erosional landforms and landscapes. Depositional landforms and landscapes.
3 of 8
Outputs
Dissipation of wave energy. Accumulation of sediment above tidal limit. Sediment removed beyond local sediment cells.
4 of 8
Dynamic Equilibrium
A balance between inputs and outputs
5 of 8
Feedback Mechanisms
Negative: impacts are nulified/reduced by subsequent knock-on effects. Positive: action leads to something becoming more than it was before.
6 of 8
Feedback Mechanisms
Beach in dynamic equilibrium--- Sediment eroded from beach during storm--- Sediment deposited offshore forming an offshore bar--- waves forced to break before beach, dissipating energy and reducing further erosion.--- Storm calms, normal wave conditi
7 of 8
Landform+ Landscapes
Landform= individual feature along a coastline, formed by coastal processes. Landscape= combination of landforms to create a landscape, e.g erosional or depositional or concordant or discordant coasts.
