A tropical rainforest is an ecosystem that occurs roughly within 28 degrees north or south of the equator (equatorial zone between the Tropic of Cancer and Tropic of Capricorn). They are characterised by their humidity (average of 88% in the rainy season and 77% in the dry season)‚ hot temperature (average 27.9 °C during the dry season and 25.8 °C during the rainy season) but more importantly their extremely high rainfall (torrential rainfall - between 1‚500 mm and 3‚000 mm annually).

To what extent can preparedness mitigate the impacts of tropical revolving storms? (40 marks) Tropical revolving storms can be referred to as Hurricanes‚ cyclones and Typhoons these occur in the Atlantic‚ Indian and pacific oceans. Nobody is quite sure how they form but certain factors do need to be met for one to form. One of these is the temperature of the sea which has to be above 28degrees‚ the water also has to be deep beneath the storm‚ this is how the storm gathers its energy. These storms

Causes and consequences of reduced biodiversity in tropical rain forests In many tropical countries‚ the majority of deforestation results from the actions of poor subsistence cultivators. However‚ in Brazil only about one-third of recent deforestation can be linked to cultivators. A large portion of deforestation in Brazil can be attributed to land clearing for pastureland by commercial and speculative interests‚ misguided government policies‚ inappropriate World Bank projects‚ and commercial exploitation
