GEOGRAPHY Chapter 6: Human Environment Interactions- the tropical and the subtropical Regions
(1) Human Environment Interactions- the tropical and the subtropical Regions 06 HumanEnvironmentInteractions-thetropicalandthe subtropical Regions Life in the Amazon Basin A basin is a portion of land which is drained by a river and its tributaries. The Amazon Basin is drained by the River Amazon- the second longest river in the world. The river basin drain parts of Brazil, Peru, Ecuador, Bolivia, Columbia and a small portion of Venezuela into the Atlantic Ocean. Climate • The Amazon Basin is also called the equatorial region as it lies very close to the Equator. It is located between 10°N and 10°S. • Since the Amazon Basin lies in the equatorial regions, it has a hot and wet climate throughout the year. Both the days and nights are equally hot and humid here. • Rainfall occurs almost every day. • The day temperatures are very high while the nights are cooler but with high humidity. Rainforests • Since heavy rainfall occurs daily, the region has a thick forest cover. At some

Hence, the ground remains dark and damp. • The Amazon rainforests are known for their wide variety of fauna. Toucans, colourful parrots, and humming birds are largely found in these forests. • Animals such as monkeys, tapirs and sloths are also commonly found in the rainforests. • Various species of reptiles and snakes are also found in this region including anacondas and boa constrictors, which are two species of snakes. • Many varieties of small insects are also found in these forests. The Amazon Basin is a home of several species of fishes. Piranha- the flesh eating fish is also found in this region. People • People in this region grow their food in small areas after clearing a patch of forests usually using slash and burn cultivation. • In this kind of cultivation, farmers first cut down the trees and burn them. The ashes of the burnt trees release nutrients into the soil making it fertile. Crops are then planted into the cleared area. After a few years of cultivation, the land loses its fertility and hence the farmers abandon the land and clear another patch of land for cultivation. • The staple food of the people is manioc, also known as cassava which grows underground like potato. • People also eat queen ants and egg sacs. • Cash crops which are grown here are coffee, maize and cocoa. • People live in houses called ‘maloca’ which have a slanting roof.
