Which of the following statements about natural disasters in the united states and canada is false? a. more tornadoes occur in the united states and canada than in any other region. b. in north america, earthquakes tend to impact the pacific coast more than other regions. c. a storm belt called tornado alley stretches across the midwestern and southern united states. d. the ring of fire is a series of tornadoes that sweep across north america annually.

The correct answer is - D. The Ring of Fire is a series of tornadoes that sweep across North America annually.

The Ring of Fire is not a series of tornadoes that sweep across North America, but instead it is a chain of volcanoes, the longest chain of volcanoes in the whole world in fact.

This chain of volcanoes is arranged alongside the boundary the of the Pacific tectonic plate. This plate has boundaries with continental plates, and it is subducting bellow them, thus making a space from where the magma from the mantle can rise to the surface of the Earth. As the magma rises, it lifts its surrounding area, and creates volcanoes, thus the Ring of Fire.
