Final answer:
The main destructive actions of tornadoes do not include a strong high-pressure zone in the center blowing buildings apart; tornadoes have a low-pressure center contributing to their destructive power. The correct option is D.
Step-by-step explanation:
The main destructive actions of tornadoes include high-wind speeds that blow away buildings and trees, winds rushing up the funnel, creating a lifting force in the updraft, and an explosive situation due to differences in air pressure between the low pressure inside the tornado funnel and the higher pressures outside.
However, the statement that a strong high-pressure zone in the center blows buildings apart is incorrect; tornadoes are characterized by a low-pressure center. This low pressure is what contributes to the lifting action and explosive force when structures encounter the tornado's vortex. The correct option is D.
