Which of the following are true about tornadoes?

The choice indicating that tornadoes may travel a path of more than 100 miles is accurate, as some tornadoes are known to traverse extensive distances due to the nature of their formation and movement patterns. Tornadoes can form from supercell thunderstorms, which can remain active for a long time, allowing the tornadoes themselves to persist and potentially travel greater distances.

For comprehensive context, it's important to note that while tornadoes have recorded wind speeds that can reach up to 300 mph, particularly in the most violent tornadoes, this fact alone does not support the choice identifying the tornado's path length. Similarly, tornado diameters can vary significantly, with most tornadoes being narrower than 300-400 feet, indicating that while they can be wide, they are not generally that large. The option discussing their speed on Earth also presents an incomplete view as although some tornadoes can rapidly rotate, the maximum sustained wind speeds are often emphasized over simple ground speed.
