This topic covers the ideas of tropical and subtropical region
Introduction to CBSE Class 7 Social Science Geography Chapter "Human-Environment Interactions: The Tropical and the Subtropical Region"
The chapter on “Human-Environment Interactions” delves into the relationship between humans and their surroundings in the tropical and subtropical regions of the world. It outlines the characteristics of these regions, such as climate, flora, fauna, and how these factors influence the livelihood of the people residing there. Students learn about the diverse ways in which communities adapt to and modify their environment to meet their needs, whether through agriculture, urbanization, or conservation.
The chapter further illustrates the concept of adaptation by highlighting how indigenous populations use natural resources judiciously, ensuring sustainability. It also discusses the consequences of human actions on these environments, including deforestation, soil erosion, and loss of biodiversity. Through this chapter, students gain an understanding of how human actions can both harmonize with and disturb the ecological balance, emphasizing the importance of responsible environmental management.

Questions and Answers for CBSE Class 7 Social Science Geography Chapter "Human-Environment Interactions: The Tropical and the Subtropical Region"
- Q1: What defines the tropical and subtropical regions?
ANS: These regions are defined by their warm climates, with the tropical zone located around the equator and the subtropical zone lying just beyond it, characterized by hot or temperate weather. - Q2: How do humans interact with their environment in these regions?
ANS: Humans interact with their environment by engaging in agriculture suited to the climate, utilizing local flora and fauna, and adapting their lifestyle to the climatic conditions. - Q3: What are some adaptations of the indigenous people in these areas?
ANS: Indigenous people have adapted through practices like shifting cultivation, terrace farming, and the use of local materials for housing and tools. - Q4: Why is biodiversity important in the tropical and subtropical regions?
ANS: Biodiversity is important as it ensures a healthy ecosystem, provides resources for humans, and maintains ecological balance. - Q5: What impact does deforestation have on these regions?
ANS: Deforestation can lead to soil erosion, loss of habitat for wildlife, changes in climate, and a reduction in biodiversity. - Q6: How does agriculture affect the environment in the tropical and subtropical regions?
ANS: Agriculture can affect the environment through the clearing of land, use of water resources, and the introduction of chemicals or non-native species that may alter the natural ecosystem. - Q7: What role does urbanization play in changing these regions?
ANS: Urbanization can lead to the spread of cities into natural areas, pollution, habitat destruction, and changes in local climate and ecosystems. - Q8: How can we mitigate the negative effects of human interaction in these regions?
ANS: We can mitigate negative effects by promoting sustainable practices, conserving natural habitats, reducing pollution, and supporting local conservation efforts. - Q9: What are the consequences of soil erosion in the tropical and subtropical regions?
ANS: Soil erosion can reduce agricultural productivity, increase the risk of natural disasters like landslides, and lead to the loss of soil fertility. - Q10: How is climate change impacting the tropical and subtropical regions?
ANS: Climate change is impacting these regions through altered rainfall patterns, more extreme weather events, shifts in growing seasons, and increased pressure on water and biological resources.
