NCERT GEO 7 Ch10 | LIFE IN THE DESERTS | Sahara (Hot) & Ladakh (Cold) Deserts |

Описание: Welcome to Simplified UPSC by : ! In this comprehensive discussion, we'll dive deep into NCERT Class 7 Geography, Chapter 10: "Life in the Deserts" ( ).

This chapter is a fascinating study of environmental adaptation and human survival, crucial for UPSC Geomorphology and Environmental Science.

Our SimplifiedConvo format (Conceptual Analyst & Factual Specialist) breaks down the contrasting biomes of the world's most extreme deserts:

We begin with the **Hot Sahara Desert**exploring its vast geographical spread across 11 nations, the extreme diurnal temperature range, unique adaptations of flora (Cactus, Date Palms) and fauna (Camel, Scorpion), and the resilience of communities like the Tuareg and Bedouins. We also analyze the transformative impact of recent oil, gas, and mineral discoveries on traditional lifestyles.

Next, we journey to the **Cold Desert of Ladakh**. We examine its location in the rain shadow of the Great Himalayas, its severe cold climate, sparse vegetation (Willow, Poplar), and the distinctive wildlife, including the Yak and the endangered Chiru (Shahtoosh deer). We also discuss Ladakh's rich Buddhist culture (Gompas like Hemis) and the challenges posed by tourism and climate change.

We conclude with essential UPSC Prelims Pointers and a detailed Mains perspective on human-environment interaction, the importance of traditional knowledge, and sustainable development in fragile desert ecosystems.
