Total questions: 20
Worksheet time: 2hrs 40mins
Engineers are designing a bridge that will better withstand earthquake forces. What is the process called when engineers use a computer to see what happens to their design during an earthquake?
variables
modeling
prediction
navigation
What is the best method for a geologist to find a scientific explanation for varying levels of damage in a city after an earthquake?
Review local newspaper reports
Conduct a survey of residents in each area
Create a compute model that takes into account different variables
Analyze the strength of previous earthquakes that have struck the same area
Scientists and engineers work together to try to reduce the damage from natural hazards. Which term is used to describe this process?
mitigation
technology
scientific method
controlling variables
A scientist is constructing a device that will predict exactly where hurricanes will travel. This device could save many lives but will be extremely expensive. Which term describes the high cost of this device?
benefit
criteria
constraint
technology
Engineers have been asked to develop a plan to reduce the effects of hurricanes on a coastal community. Which is the first step engineers should take when developing a plan to reduce the effects of a natural hazard?
Identify the need
propose a solution
evaluate the solution
determine the criteria and constraints
This data table shows information about earthquakes in Northern California. Which strategy is the most practical way to mitigate damage to buildings as a result of earthquakes in this area?
research methods of preventing earthquakes from happening
educate the public about how to respond in case of an earthquake
research methods of designing buildings to withstand earthquakes up to magnitude 8.0
design early detection systems to know when an earthquake larger than magnitude 5.0 will happen next
A hurricane destroyed a coastal town. Afterward, the town was rebuilt. Which term describes the rebuilding process after a natural disaster?
response
recovery
mitigation
preparation
Which process would be an important part of preparatin for a hurricane that is about to strike the city in the photo?
build buildings farther from the coastline
determine how to keep traffic moving during an emergency
use boats to move emergency responders to the island if bridges are closed
clean up the area so people can return as soon as possible
Which of these actions would likely be a part of a hazard mitigation plan to reduce the negative impacts of a blizzrd? Select (ALL) that apply.
warning about a blizzard before it arrives
clearning snow from the street as quickly as possible after the storm
having emergency response personnel availalbe when the snow begins
assigning work crews to repair damage caused by the weight of the snow
Many cities do no allow parking on the street when a blizzzard has been predicted. How might parked cars interfere with hazard mitigation?
Poeple cannot get cars out of the parking spaces to drive to work
Parked cars force traffic to move slower
Snow-covered cars on the street slow down emergency responders
The cars make the snow appear worse than it really is
An engineer is asked to design a bridge that can withstand a 8.0 magnitude earthquake and 100 Mph wind gusts. Which term describes the requirements that the engineer must refer to when designing the bridge?
benefit
criteria
constraint
technology
Technology is useful in identifying hazard probability, in developing mitigation plans, in testing solutions, and in response and recovery.
True
False

greater, less
less, greater
greater, more
less, more
