Earth's Natural Hazards

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 only show physical structures, not events such as hurricanes.

A hurricane was predicted and people were asked to evacuate from an area. The area experienced a strong hurricane. Which description of damage is most typical for this type of natural disaster?

• lightning damaged many buildings

• air quality became unsafe for many people

• buildings and bridges collapsed without warning

• many structures were damaged by flooding and wind

Alicia wants to buy a house. She does not want to buy a house in an area where earthquakes and flooding are common. Which information would help her most in choosing where to buy a house?

• a map that includes elevation of land and location of faults

• a map that shows typical rainfall and location of volcanic activity

• a graph of the number of earthquakes and floods in the last ten years

• a graph of how much damage is caused by earthquakes compared with floods
