The grinding away of bedrock by fragments of rock which may be incorporated in ice. Also known as corrasion
1 of 50
Strategies designed to prepare for and reduce the impacts of events
2 of 50
The part of the mantle, below the lithosphere, where the rock is semi-molten
3 of 50
The gradual wearing down of rock particles by impact and abrasion, leading to a reduced particle size and rounder, smoother stones
4 of 50
Benioff Zone
The area where friction is created between colliding tectonic plates, resulting in intermediate and deep earthquakes
5 of 50
Concordant Coast
Where bands of more-resistant and less-resistant rock run parallel to the coast
6 of 50
Convection Currents
Hot, liquid magma currents moving in the asthenosphere
7 of 50
The breaking down of rock by chemical action, often involving the dissolving of alkaline rock by weak acids in seawater
8 of 50
Cost-Benefit Analysis
A process by which the financial, social and environmental costs are weighed up against the benefits of a proposal in terms of social outcomes as well as in terms of profit and loss
9 of 50
Crustal Fracturing
When energy released during an earthquake causes the Earth's crust to crack
10 of 50
Dalmatian Coasts
A type of concordant coastline formed as a result of a rise in sea level when valleys flooded leaving the tops of the ridges above the surface of the sea as offshore islands
11 of 50
Discordant Coasts
The geology alternates between bands of more-resistant and less-resistant rock, which run at right angles to the coast
12 of 50
Where sediment is transferred along the coast by longshore drift producing a pattern of sediment size and roundness which varies between one location on a beach and another
13 of 50
Emergent Coastline
When a fall in sea level exposes land previously covered by the sea
14 of 50
Environmental Impact Assessment (EIA)
A quantitative means of estimating the environmental changes arising from a proposal
15 of 50
The point on the Earth's surface directly above the focus of an earthquake
16 of 50
Eustatic Change
When the sea level itself rises or falls, partly as a result of the growth and decay of ice sheets - occurs globally
17 of 50
The point inside the Earth's crust from which the pressure is released when an earthquake occurs
18 of 50
Haff Coast
A concordant coastline which consists of long spits of sands and lagoons
19 of 50
Hazard Management Cycle
A theoretical model of hazard management as a continuous four-stage cycle involving mitigation, preparation, response and recovery
20 of 50
Hot Spot
Points within the middle of a tectonic plate where plumes of hot magma rise and erupt
21 of 50
Hydrometeorological Hazards
Natural hazards caused by climate processes (including droughts, floods, hurricanes and storms)
22 of 50
Integrated Coastal Zone Management (ICZM)
A strategy designed to manage complete sections of the coast, rather than individual towns or villages, by bringing together all of those involved in the development, management and use of the coast
23 of 50
Intra-plate Earthquakes
Earthquakes which occur far from plate margins
24 of 50
Isostatic Change
When the land rises or falls, relative to the sea, often in response to the melting or accumulation of glacial ice - occurs locally
25 of 50
L Waves
The slowest seismic waves, which focus all their energy on the Earth's surface
26 of 50
Land-use Zoning
A process by which local government regulates how land in a community may be used
27 of 50
When the violent shaking during an earthquake causes surface rocks to lose strength and become more liquid and solid
28 of 50
The solid layer, made from the crust and upper mantle, from which tectonic plates are formed
29 of 50
Littoral Zone
Another name for the coastal zone: the boundary between land and sea which stretches out to sea and onto the shore
30 of 50
Longshore Drift
The movement of sand and shingle along the coast
31 of 50
Mass Movement
The downward movement of material under the influence of gravity. It includes a wide range of processes such as rockfalls, landslides and solifluction
32 of 50
Action to reduce the impacts of an event
33 of 50
Multiple Hazard Zone
An area that is at risk from multiple natural hazards such as hurricanes and earthquakes
34 of 50
P Waves
The fastest seismic waves which travel through both solids and liquids
35 of 50
The study of past changes in the Earth's magnetic field
36 of 50
Park Model (Hazard Response Curve)
Shows how a country or region might respond after a hazard event
37 of 50
Pioneer Species
The first colonising plants which begin the process of plant succession
38 of 50
Pressure and Release (PAR) Model
A tool used to work out how vulnerable a country is to hazards
39 of 50
S Waves
Seismic waves which only travel through solids and move with a sideways motion
40 of 50
Sediment Cells
A length of coastline and its associated nearshore area within which the movement of coarse sediment (sand and shingle) is largely self contained. There are 11 sediment cells around England and Wales some of which can be divided into sub-cells
41 of 50
Shoreline Management Plan (SMP)
A plan that takes into consideration the risks of coastal processes and attempts to identify sustainable coastal defence and management options
42 of 50
Slab Pull
When newly formed oceanic crust sinks into the mantle, pulling the rest of the plate further down with it
43 of 50
A form of mass movement which is the flow downhill flow of saturated soil
44 of 50
Sub-Aerial Processes
The processes of weathering and mass movement
45 of 50
Subduction Zone
The area in the mantle where a tectonic plate melts
46 of 50
Submergent Coastline
When a rise in sea level floods a previously exposed coast
47 of 50
Where sediment moves up and down the beach with little lateral transfer
48 of 50
Swell Waves
Waves originating from the mid-ocean which appear as larger waves amongst smaller, locally generated waves
49 of 50
Transform Fault
A fault created on a large scale when two plates slide past eachother
