ENVIRONMENT FINAL TEST 2026
QUESTIONS WITH CORRECT ANSWERS
GRADED A+
◍ Definition of natural hazard.
Answer: A natural process which could cause death, injury or disruption to
humans, or destroy property and possessions.
◍ Geography.
Answer: The study of the natural/physical environment and the
cultural/human environment from a spatial perspective
◍ Types of natural hazards.
Answer: 1. geological hazards2. meteorological hazards
◍ how are geological hazards caused?.
Answer: caused by land and tectonic processes e.g volcanoes, tsunami and
earthquakes
◍ Sustainability.
Answer: Maintaining the capacity of the environment to support our lives
and the lives of other living creatures.
◍ how are meteorological hazards caused?.
Answer: caused by weather and climate e.g tropical storms, blizzards and
tornadoes
◍ Biome.
Answer: Places that share similar climate and life forms. Often referred to as
ecosystems.
,◍ What factors affect the hazard risk of natural hazards.
Answer: vulnerability, capacity to cope and nature of natural hazards
◍ how does vulnerability affect hazard risk.
Answer: more people in an area exposed to natural hazards, the greater
probability they will be affect by a natural hazard e.g an area with high
population density on a flood plain (much of Bangladesh) is very vulnerable
to flooding
◍ how does capacity to cope affect hazard risk (example).
Answer: the better a population can cope with an extreme event the lower
risk of them being severely affected e.g HICs are better at coping with
flooding because they can afford to build flood defences and evacuate
people
◍ how does nature of natural hazards affect hazard risk.
Answer: 1) type - the risk from some hazards are greater than others e.g
tropical storms are able to be predicted and monitored gives people more
time to evacuate but earthquakes happen suddenly with no warning harder to
protect people2)frequency - natural hazards that occur more often may carry
a higher risk3) magnitude - more severe natural hazards tend to have the
greatest effects e.g a magnitude 9.0 earthquake in Japan 2011 killed over
15000 people whereas a 6.3 magnitude earthquake in Italy 2009 killed
around 300 people
◍ what are the primary effects of natural hazards.
Answer: *buildings and roads are destroyed *people are injured or killed e.g
when a building collapses *crops and water supplies can be damaged or
contaminated*electricity cables, gas pipes and communication networks can
be damaged (cutting off supplies)
◍ Food security.
Answer: All people have access to enough food to sustain a healthy lifestyle
◍ what are the secondary effects of natural hazards.
Answer: *the initial hazard can trigger other hazards e.g earthquakes can
, trigger tsunamis*aid and emergency vehicles can't get through because of
blocked roads or bridges (cause more deaths)*a shortage of clean water and
lack of sanitation makes it easier for disease to spread*food shortages if
crops are damaged, livestock are killed or supply lines are blocked
*country's economy can be weakened by damage to businesses (causes
unemployment) and reconstruction processes are very expensive
◍ what are the immediate responses of natural hazards.
Answer: * evacuate people (before hazards occurs if possible)* treat the
injured and rescue anyone cut off by damage to roads or bridges* recover
dead bodies to prevent disease spreading* provide food, drink and shelter to
people without homes* provide temporary supplies of electricity and gas if
regular supplies have been damaged
◍ what are the long term responses of natural hazards.
Answer: * repair homes or rehouse people who have lost their homes* repair
or rebuild buildings, roads, railways and bridges * boost economy recovery
e.g by promoting tourism* reconnect broken water, electricity, and gas if
regular supplies have been damaged
◍ what is the tectonic plate theory.
Answer: the earth's crust is divided into slabs called tectonic plates that float
on the mantle which move due to convection currents that occur in the
mantle
◍ what are the two types of crust plates are made of.
Answer: 1. continental crust is thicker and less dense (30-50 km)2. oceanic
crust is thinner and more dense (5-10 km)
◍ what is it called where the plates meet.
Answer: plate margins or plate boundaries
◍ what are the three types of plate margin.
Answer: 1) Destructive margins2) Constructive margins3) Conservative
margins
◍ what is a conservative margin.
, Answer: conservative margins are where two plates are moving sideways
past each other, or are moving in the same direction but at different speeds
e.g the pacific plate is moving in the same direction as the north american
plate but faster
◍ what is the constructive margin.
Answer: constructive margins are where two plates are moving away from
each other e.g the eurasian plate and the north american plate away from one
anothers forms the mid-atlantic ridge
◍ what is the destructive margin.
Answer: destructive margins are where two plates move towards each other
e.g the oceanic nazca plate is being subducted beneath the continental south
american plate creates the atacama trench
◍ what plate margins does a volcano occur at.
Answer: destructive and constructive plate margins
◍ how does a volcano occur at a destructive margin.
Answer: the denser oceanic plate moves down into the mantle, where it
melts a pool of magma forms then rises through cracks in the crust called
vents. The magma (called lava when reaches surface) erupts forming a
volcano
◍ how does a volcano form at a constructive margin.
Answer: the magma rises up into the gap created by plates moving apart
forming a volcano
◍ What plate margins do earthquakes occur at.
Answer: destructive, constructive and conservative plate margins
◍ how does a earthquake occur at a destructive margin.
Answer: tension builds when one plate gets stuck as it moves past the other
◍ how does a earthquake occur at a constructive margin.
Answer: tension builds along cracks in the plates as they move away from
each other
