Natural Disasters: Final Exam Questions With Complete
Solutions
100 year flood Correct Answers has a 1% chance of happening
during any given year
Andesite and Rhyolitic magmas Correct Answers Moderate to
high silica and much gas, high viscosity, low temperature
ash flows (pyroclastic) Correct Answers mix of hot gasses and
some magma, Calderas often produced.
Basalt Magma Correct Answers Low silica, gas, and viscosity.
High temperature, found most commonly in divergent plate
boundaries
Bores Correct Answers single wave crests that move along
rivers up stream
Caldera Correct Answers collapse of roof of a magma chamber
Causes of thunder storms Correct Answers rapidly rising air,
rain- development of down drafts, descending air.
Cinder Cones Correct Answers Coarse pyroclasts, small and
steep slopes, common in other volcanoes and lava fields
Cold Front Correct Answers Cold air mass pushes into warm air
mass, sudden temperature change associated with heavy but
brief rain. May be associated with severe thunderstorms.
, Competence Correct Answers largest size of material that a
stream can carry
Composite Volcanoes Correct Answers alternating lava and
pyroclasts, intermediate sizes and slopes, found on convergent
plate boundaries
Convergent Boundaries Correct Answers Where two plates
move toward each other
Coriolis Effect Correct Answers Moving air is deflected by the
earth rotation, rotational velocity of the earths surface is greatest
at the equator and weakest at the poles. In the northern
hemisphere wind is deflected to the right, and in the southern
hemisphere it is directed to the left.
Coriolis effect on pressure systems Correct Answers Clockwise
rotation around high pressure and
counterclockwise rotation around low pressure
in northern hemisphere.
dam construction Correct Answers increases water storage
Damburst flood Correct Answers failure of a dam or levee
Discharge Correct Answers The volume of water passing
through a stream per unit time
displacement floods Correct Answers wave generated by
landslide into body of water
