     | The largest and most populated island of 
    the seven which make up the Canary Archipelago, Tenerife lies northwest of 
    the African continent. Its shape is triangular and was formed as a result of 
    the massive volcanic eruptions, which once dominated the area. The island's 
    original economy was based on agriculture, including the harvesting of 
    bananas, potatoes and tomatoes. However, new industrial activities, such as 
    oil, tobacco and paper mills have slowly appeared. Tourism is the main 
    industry at present. |
