Life in the Natural Regions: The Tropical and Subtropical Regions – Class 7 Notes
Introduction
Natural regions are areas on the Earth's surface that exhibit uniform climatic, vegetative, and human activity patterns. Understanding these regions helps us appreciate how diverse life on Earth can be and how humans have adapted to varying environmental conditions.
The Tropical and Subtropical Regions
The tropical and subtropical regions are vast areas extending from the equator to 30° north and 30° south latitudes. The Tropic of Cancer marks the northern boundary, while the Tropic of Capricorn marks the southern boundary.
Climatic Characteristics
These regions experience high temperatures and significant rainfall, which influence their biodiversity. Climatic variations within these broad belts lead to different natural regions such as dense rainforests, hot deserts, dry grasslands, and monsoon areas.
Types of Natural Regions in the Tropical Belt
Dense Rainforest
Characterised by dense, multi-layered vegetation, these areas receive high rainfall throughout the year.
Tropical Hot Deserts
These areas are extremely dry, with very little rainfall and scarce vegetation.
Dry Grasslands
These regions receive moderate rainfall, supporting grasses and few trees.
Tropical Monsoon Regions
These areas experience distinct wet and dry seasons with seasonal monsoon rains.
Life in the Amazon Basin
The Amazon Basin, a symbol of tropical rainforests, covers an area of 7 million square kilometres in South America. It is the most extensive river basin globally, with its rainforest, known as 'Selva', covering around 5.5 million square kilometres.
Climate in the Amazon Basin
The Amazon Basin experiences an equatorial climate with high temperatures and humidity year-round. It receives heavy convectional rainfall, particularly in the afternoons, resulting in over 200 cm of rainfall annually.
Natural Vegetation
The Amazon Rainforest, or 'Selva', is dense and evergreen. It boasts the highest plant species diversity on Earth, with an area of one square kilometre containing thousands of tree and plant species.
Wildlife in the Amazon Basin
The rainforest is home to an incredible array of wildlife, from the giant anaconda to the colourful macaw. The thick forest canopy provides various habitats supporting diverse bird species, mammals, reptiles, and insects.
Indigenous People and Their Adaptations
The Amazon's indigenous tribes live by hunting, fishing, and gathering forest produce. They practise shifting cultivation, clearing small forest areas for temporary farming.

D --> E[Move to new area]
Threats to the Amazon Rainforest
Deforestation due to logging, agriculture, and mining poses a significant threat to the Amazon. This destruction leads to biodiversity loss, severe soil erosion, and contributes to global warming.
Life in the Ganga-Brahmaputra Basin
In contrast, the Ganga-Brahmaputra Basin in India offers more favourable living conditions. This subtropical region encompasses the fertile plains formed by the Ganga and Brahmaputra rivers.
Environmental Conditions
The basin experiences a tropical monsoon climate with hot summers, a rainy season, and cold, dry winters.
Natural Vegetation in the Ganga-Brahmaputra Basin
The basin supports tropical deciduous forests, evergreen forests in some parts, and mangrove forests in the delta regions.
Wildlife in the Ganga-Brahmaputra Basin
It is home to the Bengal tiger, one-horned rhinoceros, elephants, and diverse fish species, among other wildlife.
Human Activities and Impact
Agriculture is the main occupation, with rice and wheat being the principal crops. The fertile soil, ample water supply, and favourable climate support dense human populations and extensive cultivation.
Industrial activities and pollution pose threats, with industrial waste and sewage contaminating rivers and degrading soil quality.
Conclusion
Understanding the diverse natural regions of the tropical and subtropical zones highlights the importance of preserving these environments. Both the Amazon and the Ganga-Brahmaputra basins are crucial for the planet's biodiversity and human livelihoods, making their conservation essential for our future.
By appreciating and protecting these regions, we ensure the survival of countless species and the sustainability of human activities that depend on these unique ecosystems.
