NCERT Solutions for Class 7 Social Science Geography Chapter 8: Human-Environment Interactions: The Tropical and the Subtropical Region

The chapter Human-Environment Interactions: The Tropical and the Subtropical Region contains topics about the life people lead in different natural regions of the world. The student will learn some of the topics- Life in the Amazon basin, Life in rainforests, Life in the Ganga Brahmaputra Basin, etc. The chapter explains the different people who live globally regarding their food habits, wearing, and habitation pattern.

This chapter will learn about the river Amazon that flows through a tropical region close to the equatorial region. Due to its long nature, numerous tributaries join the Amazon River to form the Amazon Basin. The river basin drains portions of Brazil, parts of Peru, Bolivia, Ecuador, Columbia and a small part of Venezuela. The Amazon Basin stretches directly on the equator and is characterised by hot and wet climate throughout the year. The day temperature in this region is high during the day and falls at night and many other factors of the Amazon.

Apart from this, we will understand how people, especially the indigenous tribes sustained themselves in the hot and very humid climate and made agriculture for themselves using the water of the Amazon to make a civilisation that sustains along the river-side just like any other civilisation of the time. We will also understand the key role the environment played on the people living in the region. How trees affect the tropical region and how the people use it to make their shelters and use the sunlight they get has been covered in the chapter.
