EARTH SCI 2GG3 COMPREHENSIVE EXAM
STUDY GUIDE WITH COMPLETE
SOLUTIONS
●● Tsunamis
Answer: - wave produced by the sudden movement of mass against
water
- wavelength exceeds that of storm waves and travels much faster
●● Mass Wasting
Answer: - involves sudden drop of a mass of rock from a vertical cliff or
overhang
●● Volcanic Erruption
Answer: - event during which lava and or pyroclastic debris is expelled
from a volcanic vent
●● Thunderstorms
Answer: - cumulonimbus cloud that produces thunder and lightning
●● Tornado
Answer: - nearly vertical, funnel shaped cloud which air rotates violently
,- range from 100m to 1 km
●● Flood
Answer: - water covers a significant area that is normally dry
- stream floods when its discharge overtops the stream basin and
submerges area outside channel
●● Drought
Answer: - extended periods of little or no rain
●● Wildfires
Answer: - uncontrolled, self-sustaining blaze sweeping across the
landscape
●● Meteorite Impacts
Answer: - point of collision of an object from space with the earth
●● Natural Hazard
Answer: - phenomenon or process that exists independently of people
(volcano)
- has potential to harm people or property
- not all hazards are considered disasters
, ●● Natural Disaster
Answer: - hazard becomes disaster when causes significant number of
human causalities and economic loss
- all disasters are considered a hazard
●● Rapid-onset Disaster
Answer: - happens so quickly evacuation is not possible
- often highest death tolls
●● Slow-onset Disaster
Answer: - can take days or weeks to develop
- provides enough time for people to prepare
●● Stealth Disaster
Answer: - can take months, years or decades to develop
e.g. sea levels rising
●● Chronic health disasters
Answer: - long term contact with earth materials that can cause disease
e.g. arsenic poisoning, lung cancer, mercury
●● Primary Disaster
