Hazards Flashcards
(27 cards)
What is adaptation?
Alteration or adjustment in response to a changed environment.
What are atmospheric hazards?
Hazards created from atmospheric and/or weather processes.
Examples include storms, heat waves, cold waves, cyclones, droughts, hurricanes, tornadoes, and wildfires.
What does the concept of change involve?
It involves both time and space, as geographical phenomena are constantly changing.
What is diffusion?
The transfer or dispersal of cultural elements from one group of people to other groups of people.
What is distribution in geography?
The spatial distribution of geographical phenomena throughout the world.
Examples include earthquake hazards and fashion design.
What does duration refer to in the context of hazards?
The length of time that a hazard event lasts.
For example, most Ebola outbreaks in West Africa lasted for a year or more.
What is an ecological hazard?
A biological or chemical hazard that can adversely impact the wellbeing of people or the environment.
What is economic integration?
An outcome of the reduction or elimination of barriers to the flow of goods, services, and factors of production between nations.
What does the term environment refer to?
The living and non-living elements of the Earth’s surface and atmosphere.
What does frequency refer to in hazard events?
How often a hazard event occurs in a particular area or country.
What are Geomorphic hazard?
Geomorphic hazards are hazards that are created by the movement of the Earth’s surface or crust.
Examples are plate tectonic movements, earthquakes, volcanic eruptions and movement induced landslides.
What is Global distribution?
The spatial distribution of geographical phenonmena overtime throughout the world.
What is Globalisation?
The increased interconnectedness and interdependence of people and countries resulting from the expanding integration of trade, finance, people, and ideas in one global marketplace.
What is hazard?
Phenomena that occur when the forces of nature combine to become destructive and have potential to damage the environment and endanger communities.
What is Human Processes?
The actions of humans that can affect the impact of a hazard, e.g. clearing land, removing barrier systems, building in low lying areas, building earthquake resistant buildings.
What are Hydrological Hazards?
Hydrological hazards are those that involve the movement and distribution of water.
Examples of hydrological hazards include flooding, water induced landslides, king tides, coastal erosion
What is Magnitude?
The strength of a hazard, or how large and important a natural hazard event is.
What is Mitigation ?
Mitigation involves the implementation of the strategies to eliminate or minimise the severity of a hazard or similarly adverse occurrence.
What is Natural Hazard?
Atmospheric, hydrological and geomorphic processes and events in our environment that have the potential to affect people adversely.
What is Preparedness?
Preparedness involves planning the interventions required to prevent the effects of the hazard. This includes being able to respond to and cope effectively with the impacts.
What is Probability?
A prediction that a hazard event will occur based on scientific observations or relevant factors to the hazard.
What is Risk management
The identification of the probability of a hazard and the vulnerability of the population that may be affected.
What is Spatial Association?
The relationship between the distribution patterns of different phenomena on the Earth’s surface.
What is Spatial Distribution?
The arrangement of geographical phenomena or activities across the Earth’s surface.
