Havana to London 25N 50N

I successfully completed this journey in two tries. I was successful because I figured out how to use the winds. The main winds I used were prevailing westerlies and horse latitude.

Lima to Cape Town 10S 30S

I completed the sailing trip from Lima to Cape Town in one try. I was successful because I used the winds to navigate me around the island I had to past in the beginning of the voyage. The rest of the way was a piece of cake. The main winds I used were trade winds and polar easterlies.

San Francisco to Sydney Australia 40N 25S

I was successful on my sailing trip from San Francisco to Sydney Australia in two attempts. I was successful because I used the winds correctly. Some of the winds that I used to be successful were trade winds, prevailing westerlies, and horse latitudes.

Acid Rain

Rain is naturally acidic however acid rain contains more acid than normal. Acid Rain is formed when nitrogen oxides and sulfur oxides combine with water in the air to form nitric acid and sulfuric acid. Acid Rain is sometimes strong enough to damage the surfaces of buildings and statues. Acid Rain also harms lakes and ponds to the point where it makes it hard for animals to survive in it or for animals to drink it.
