The document provides information about natural hazards, specifically tornadoes. It includes: 1) Objectives to learn where tornadoes strike most frequently, which areas are most affected, and how tornadoes are measured. 2) The United States experiences more tornadoes than any other country and identifies states like Oklahoma, Kansas, and Texas as areas that would be visited during tornado season. 3) Information on the Fujita scale, which is used to rate tornadoes from F0-F5 based on damage caused. A factsheet is created to show each level of the scale.
