Final answer:
A tornado family comprises multiple tornadoes that originate from the same supercell thunderstorm, each forming one after the other.
Step-by-step explanation:
The statement that best describes a tornado family is (c) Multiple tornadoes that develop from the same supercell thunderstorm. A tornado family consists of a series of tornadoes produced by the same supercell.
These tornadoes can occur in succession, each one forming after the previous tornado has lifted. Tornadoes are associated with supercells, which are a particular type of thunderstorm with a deep, persistently rotating updraft called a mesocyclone.
Tornadoes can exhibit incredible destructive power, with their funnel-like shapes spinning violently as they descend from thunderclouds. In some cases, their winds can reach speeds as high as 500 km/h, causing significant damage to structures and the environment.
The most intensive tornado activity is found in an area known as tornado alley in the central U.S., where storm chasers often follow tornadoes to gather data or for media reporting.
