Earth's Equator and Latitude Basics The equator divides Earth into two hemispheres at 0 degrees latitude, marking the center of Earth's surface division. Latitudes measure angular distance from this line north or south up to 90 degrees each way, totaling 181 latitudinal lines globally.
Important Lines of Latitude on Earth Key latitudinal lines include the Tropic of Cancer (23°30'N), Arctic Circle (66°33'N), Tropic of Capricorn (23°30'S), and Antarctic Circle (66°33'S). These define climatic zones like tropical regions receiving direct sunlight year-round between these tropics.
'Tropical Zone' Definition by Sunlight Distribution 'Tropical zone' spans areas directly under sun rays throughout the year within boundaries set by major tropics mentioned earlier; beyond them lies temperate zones experiencing slanted solar radiation instead due seasonal tilts affecting heat distribution patterns worldwide accordingly!
India's Land and Coastal Boundaries India shares a 15,200 km land boundary with neighboring countries and has a coastal line of 7,516.6 km. The country is bordered by nine states along the coastline and four union territories. Neighboring nations include Bangladesh (largest border), China (McMahon Line), Pakistan (Radcliffe Line), Nepal, Myanmar, Bhutan, Afghanistan (Durand Line). Maritime neighbors are Sri Lanka and Maldives.
Geographical Divisions of India The geography of India is divided into six physiographic regions: Northern Mountains including Himalayas; Indo-Gangetic Plains; Thar Desert; Peninsular Plateau or Deccan Plateau surrounded by three water bodies forming peninsulas; Coastal Plains on both eastern/western sides; Islands like Andaman-Nicobar & Lakshadweep.
Himalayan Mountain Ranges Structure The Himalayan range consists of Outer Himalayas/Shivalik Hills at lowest elevation followed upwards to Lesser/Middle Himalaya then Greater/Inner Himachal finally

Nilgiri Hills: Meeting Point of Eastern and Western Ghats The Nilgiri Hills serve as the meeting point for India's Eastern and Western Ghats. This region is home to some of the highest peaks in southern India, including Doddabetta. The hills are also referred to as a knot due to their geographical significance.
Malwa Plateau and Chotanagpur's Rich Resources India’s Malwa Plateau lies eastward towards Bundelkhand, while Chotanagpur plateau is known for its abundant mineral resources. These regions play a significant role in shaping India's geography with fertile lands supporting agriculture.
Palghat Gap: Kerala-Tamil Nadu Connection The Palghat Pass connects Kerala with Tamil Nadu through the Western Ghats, facilitating trade routes between these states. It serves as an essential geographic feature bridging two major Indian regions.
'Deccan Region': Black Soil & Cotton Cultivation Hub 'Deccan' refers primarily to black soil-rich areas ideal for cotton cultivation across central-southern parts like Karnataka Plateaus or Telangana Plains underlain by volcanic basaltic rocks formed millions ago during lava flows creating unique agricultural landscapes today!
