This map shows areas of the United States in danger of tornadoes. Choose the THREE characteristics that make this area of the US especially prone to tornado activity

1. The central location of the area within "Tornado Alley," a region known for frequent tornado activity.

2. The convergence of warm, moist air from the Gulf of Mexico with cold, dry air from the Rocky Mountains, creating ideal conditions for tornado formation.
3. The flat terrain of the area, which allows for the unimpeded movement of storm systems and the formation of powerful tornadoes.
