Your answer, "A violently rotating column of air in contact with the ground," is indeed the correct description of a tornado. To arrive at this answer, you can eliminate the incorrect options using your knowledge and understanding of tornadoes.

1. "A large swirling low-pressure system that forms over the warm Atlantic ocean." This option describes a hurricane rather than a tornado. A hurricane forms over warm ocean waters with a distinct eye at its center, while a tornado forms over land and does not have a well-defined eye.

2. "A winter storm with wind speeds of at least 56 km/h and low visibility." This option describes a winter storm, but not specifically a tornado. While tornadoes can occur in winter, they are not exclusive to this season, nor are they defined by low visibility. Tornadoes are characterized by a rotating column of air, rather than solely by wind speeds and visibility.

3. "A violently rotating column of air in contact with the ground." This option accurately describes a tornado. Tornadoes are known for their distinctive rotation, which forms a funnel-shaped cloud or dust whirling towards the ground, making contact at the base. This spinning motion is what gives tornadoes their destructive power.

Therefore, the correct answer is option 3, "A violently rotating column of air in contact with the ground."
