Final answer:
Tsunamis in the open ocean are not big enough to capsize freighters and other large boats. The correct answer is B) False.
Step-by-step explanation:
The statement that tsunamis in the open ocean are big enough to capsize freighters and other large boats is false.
Tsunamis in the open ocean are generally less than 30 cm high on the ocean's surface, and their wavelengths can be as long as 100 km.
While tsunamis can cause significant damage and devastation when they reach shallow water near the coast, their impact in the open ocean is minimal.
It is the interaction between the tsunami wave and the seafloor as it approaches the coast that causes the wave height to increase dramatically.
Therefore, the correct answer is B) False.
