The map below shows the ocean currents and prevailing winds that surround South America. Before the Panama Canal was built, ships would have to sail around Cape Horn, the southern tip of South America, to get from the Atlantic Ocean to the Pacific Ocean. How did prevailing winds and ocean currents help or work against that voyage from east to west?

The Cape Horn was one of the most important routes for maritime trade, leading to sailing vessels.

the difficulty of all this is that it presents great iceberg and climatic factors that do not help the boats. nowadays other commercial routes were created that made this channel only be transited by larger ships, or oil tankers.

Explanation:

Sailing in its waters is still considered one of the greatest nautical challenges, so there are various sporting and tourist events that use this route, some as part of the circumnavigation of the globe, among which are important yacht regattas, such as the Vendée Globe.

The winds and the current both worked against the ships.

Explanation:

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
