1.___ |
A hypothesis is a suggested explanation for an observation. The data table and your graph display a sequence of observations for Hurricane Ike. In a brief but complete sentence, state a reasonable hypothesis to explain these observations.
|
|
|
2.___ |
Describe the relationship between wind speed and air pressure within a tropical storm system.
|
|
|
3.___ |
During a hurricane one of the primary dangers is called a storm surge. Describe a storm surge.
|
|
|
4.___ |
|
In this hurricane, at which ocean shore location would the highest storm surge most likely occur - Location X or Location Y? Why?
|
|
5.___ |
For conversions refer to SmartFigure 18.2 on p.553 in your eText. Both millibars (mb) and inches of mercury are units of measure for air pressure. An air mass has air pressure of 1000 mb, using your SF, convert 1000 mb to inches (of mercury) and write it below to the nearest 1/100th of an inch.
