Itinerary and approximate latitude

Were you successful? not at first but very successful
How many attempts? 5 on each one
What winds did you take advantage of or compete with during your travel? the trade, the horse and the doldrum.
class tried to sail on the computer and we have 15 days to reach your destination.The first one i did was from Los Angles to Australia is very hard to get to get to almost impossible, but after awhile you get the hang of it and get there. then the next one is the Lima, Peru to Cape Town Africa its a lot easier,when you move u get a free push and makes he trip easier after that.The last one It starts from Havana, Cuba to London, England. It's the most simple map ever. I was successful but took a long time to get it right. Took me at least 5 times before i was successful.

ozone

The Ozone is the Stratosphere area of the atmosphere. it takes three oxygen molecules. In a nut shell, its Earths suncreen and ours from UV rays. (ultra violet) If it was in the troposphere(weather part of atmosphere)we would die because of no air and would sufficate. Unfortionatly, the Ozone is very unstable any carbon dioxide can alter it easily with other atoms cause major problems most of these problems are from the oceans and valcanos. All in all, Ozone depletion is a big problem. everything is being effected plants, animals,also humans because the ozone is getting worse that it is getting better and hope we don't lose it forever.

green house effects

A greenhouse effect is heat trapped in the atmosphere by gases that form a blanket around the Earth. Yes we should be concerned about the effects because its partly contributing to global warming which is making climate changes. This means more hurricanes rise in oceans and other castostrophic changes. To change that, people should burn less fossil fuels and coal to stop this from happening.

there are many types of pollution around the world and thats a problem. One type of pollution in the cities its Photochemical smog. the photo in photochemical means "light". This smog is made up of sunlight, hydrocarbons and nitrogen oxides. when these chemicals react it makes a brownish mix of ozone and other pollutants. The ozone protects us from UV rays. (ultra violet rays) This becomes and can harm living things. for humans it will irritate throat and lungs and animals and plants. However, we are trying to improve air quality around the world making new power plants that run cleaner than older power plants, less polluting cars but the flip side to cars is that there are more running and more fossil fuels burning in cities. Cities are still very polluted and are trying to make that better.
