Study Notes
Geological Formations and Historical Context
- Madagascar is believed to have broken off from Africa and drifted across the Indian Ocean to join mainland Asia.
- The Indus lowlands were created approximately 20 million years ago due to tectonic activity and geological shifts.
Geographic Features of Pakistan
- Pakistan has an approximate coastline of 1,046 kilometers along the Arabian Sea.
- The land area of Pakistan is around 881,913 square kilometers, making it one of the larger countries in South Asia.
Historical Ecology and Life-Forms
- Due to the land-bridge formed between Gondwanaland and Southeast Asia, life-forms such as various species of flora and fauna predominated in Pakistan east of the River Indus.
- This ecological shift also allowed for the invasion by different life-forms, making the region more biodiverse.
Indus River Origins and Himalayan Formation
- The Indus River originates from the mountains of the Himalayas, Hindu Kush, and Karakoram ranges.
- The Himalayan mountain range was formed as a result of the collision between the Indian Plate and the Eurasian Plate, a significant tectonic event that defined its current geological structure.
