Many people know that the largest tropical rainforest in the world is in the Amazon Basin of Brazil. Instead you can see grassland, pine forests and even in places semi-desert. Because to understand the reasons for the different sorts of natural environments, you need to know something about Brazil's temperature and rainfall patterns.
Brazil is divided into five regions.
Note from map that Brazil mostly lies south of the Equator. Only a small proportion of the North Region lies in the northern hemisphere. Virtually all the South Region lie south of the Tropic of Capricorn, which is some 3,000 kilometers south of the Equator. The reason is that these parts of Brazil lie within the tropics, where during the day the sun is always high in the sky. Seasons as we know them are caused by changes in the inclination of the sun at different times of the year - from high in the sky during our summer and low in the sky during our winter.
