Total questions: 20
Worksheet time: 2hrs 40mins
Which data is most helpful in predicting volcanic activity?
sea surface temperatures and wind speed
historic information about landslides and flooding
satellite data about atmospheric conditions
frequency of earthquakes and stability of land surface
A scientist wants to track a hurricane and predict where it will go next. Which tools are best for making preditions about hurricanes?
thermometers and GPS
geologic maps and tiltmeters
satellites and computer models
weather ballons and seismometers
A scientist used a model to predict the path of a hurricane. The hurricane followed a similar path but did not follow the exact path that was predicted. How does this example demonstrate a limitation of models?
Models cannot be used to predict things
Models cannot account for how every factor may suddenly change
Models can be used to predict weather events before the event occurs
Models can be used to show only physical structures, not events such as hurricanes
A town is deciding where to build a new road. There have been landslides in this town in the past. Which information will help the engineers decide where to put the road to avoid damage due to landslides?
the number of houses in different areas
the steepness of the gorund in different areas
weather predictions about amount of rainfall in different states
the number of cars expected to use the road at different times of the day
The map shows the epicenters of some major earthquakes in 2003. Based on this information, on which continent is an earthquake least likely to happen in the future?
Asia
Africa
South America
North America
The weather has been warmer than usual in a town in California. A student wants to know if warmer weather means that an earthquake is more likely to happen. Which statement about earthquakes and weather is true?
Earthquakes and weather are not related.
Earthquakes cannot happen in cold weather.
Atmospheric conditions cause both earthquakes and weather.
The movement of tectonic plates causes both earthquakes and weather.
The diagram shows how layers of information can be combined to create one map. Based on the layers present on the map, what could this map best be used for?
to study the effect erosion has had on the path of the river
to measure the distance from the town library to the school
to compare the elevation of one town with the elevation of another town
to determine which areas and streets would be most at risk for flooding
