Answer:
Hi!
The 3 main theories circulating about the nature of the thing causing ships to wreck are:
1- Floating islands of reefs
2- A monster of colossal size
3- A submarine with powerful engines
Step-by-step explanation:
In old ages, the main belief there was for ships wrecking was that there were monsters of colossal sizes out in the ocean. Because sailors spent most of their time alone in the sea, a place that had been largely undiscovered, sailors mistook many things such as reefs and submarines with powerful engines for big monsters living under the surface. Since there was no other scientific explanation at the time, sailors got convinced that the “monsters” living under the sea where strong enough to sink any ship, and they attributed boat wreckage to them.
