Final Exam Natural Disasters BYUi Questions With
Complete Solutions
A hypocenter? Correct Answers the point underground on a
fault where an earthquake starts
A tornado (or any other atmospheric vortex) is the most efficient
way to move air from one part of the atmosphere to another on
its size and time scale. Correct Answers is a scale used for
assigning an intensity rating to tornadoes. The rating assigned to
a given tornado is based on the amount of damage the tornado
causes to vegetation, landscape, and artificial structures
Are natural disasters increasing with time? Correct Answers No
we are just understanding them better.
At what point does a tropical storm become a hurricane? Correct
Answers sustained winds reach 74 mph
CInder Cones: Correct Answers Most cinder cones have a
bowl-shaped crater at the summit and rarely rise more than a
thousand feet or so above their surroundings.
Do tornadoes serve a natural purpose? Correct Answers A
tornado (or any other atmospheric vortex) is the most efficient
way to move air from one part of the atmosphere to another on
its size and time scale.
How can you tell the power capabilities of a river just by
looking at it? Correct Answers channel slope gradient (L/L)
multiplied by drainage area
, How do hurricanes form? Correct Answers We don't understand
fully, but some are apparently formed by temperature changes
across the downdraft air around the mesocyclone
In what type of material does liquefaction happen Correct
Answers Water saturated- Sandy Soils
Lava Domes Correct Answers : are formed by relatively small,
bulbous masses of lava too viscous to flow any distance;
consequently, on extrusion, the lava piles over and around its
vent. A dome grows largely by expansion from within.
Maars or tuff cones: Correct Answers maars are shallow, flat-
floored craters that formed as a result of a violent expansion of
magmatic gas or steam.
Plugs Correct Answers :Solidified magma, along with
fragmental volcanic and wall-rock materials, can be preserved in
the feeding conduits of a volcano upon cessation of activity. hip
Rock in New Mexico, Devil's Tower, Wyoming, is a prominent
volcanic neck (or plug). The monastery and statue at Le Puy-En-
Velay, France, are built atop volcanic necks (
Shield volcanoes: Correct Answers are built almost entirely of
fluid lava flows. Flow after flow pours out in all directions from
a central summit vent, or group of vents, building a broad,
gently sloping cone of flat, domical shape, with a profile much
like that of a warrior's shield.
