adaptations
actions taken to adjust to natural events such as climate change to reduce damage, limit the impacts take opportunities or cope with consequences
carbon footprints
measurement of greenhouse gases individuals produce through fossil fuels
tsunami
huge waves caused by earthquakes under the sea
tectonic hazrads
threats posed by earthquakes, volcanoes
subduction
the transformation into magma of denser tectonic plates as it divers under a less dense plate
secondary effects
the after effects of a disaster e.g. diseases spread due to dirty water, loss of economy due to destruction of business.
response
the way in which people react to a situation e.g. an earthquake
primary effects
impacts of a natural disasters that happen immediately or soon after the event
prediction
forecasting the future
plate margin
boundary between 2 tectonic plates
plates
the large pieces of broken crust that cover the earth
oceanic crust
the part of earth’s crust which is below the ocean
magnitude
size of an earthquake
focus
the point of origin of an earthquake
epicentre
the point on the ground directly above the focus of the earthquake
earthquake
a sudden or violent movement within the earth’s crust followed by a series of shock
destructive plate boundaries
a plate margin where tectonics collide
convection currents
circulating movements of the magma in the mantle caused by the heat of the core
continental crust
the part of the earth’;s crust which makes the continents
constructive plate boundaries
a plate margin were plates move apart
conservative plate boundaries
where tectonics slide past each other
climate change
a long term change in the earth’s climate especially a change due to an increase in the average atmospheric temperature
