Hurricane evacuation studies are very important as they can provide the relevant authorities with means for planning how to evacuate people during a hurricane emergency.
As such, the study would need to collect information on the characteristics of the community, its vulnerabilities, transportation capabilities and any hazards that might hinder the evacuation.
This information will enable the plan to be as inclusive of possible scenarios as possible so that the evacuation plans will have a lower chance of failure.
The bulk density of a planet will reflect the relative amounts of the materials the world is made of, regardless of what materials occur at the surface.
