Africa and Others — Core Concepts
Core Concepts
Africa, the second-largest continent covering 30.3 million km², features the Great Rift Valley system, Sahara Desert (9 million km²), major rivers including the Nile (6,650 km) and Congo (4,700 km), and extensive mineral resources producing 60% of global cobalt and 50% of diamonds.
The continent contains diverse climate zones from Mediterranean to tropical wet, supporting varied ecosystems and agricultural patterns. Australia, the smallest continent at 7.7 million km², is unique as both continent and country, featuring the Great Dividing Range, Great Barrier Reef, and vast mineral deposits in the Western Plateau.
Its isolation created exceptional biodiversity with 80% endemic plant species. Antarctica, covering 14 million km², contains 70% of world's fresh water and influences global climate through the Antarctic Circumpolar Current.
The Antarctic Treaty System governs the continent as a scientific preserve. Indian Ocean island nations including Madagascar, Mauritius, Seychelles, and Maldives serve as strategic maritime locations while facing climate change threats, particularly sea-level rise.
These geographical regions collectively demonstrate Earth's diverse landforms, climate systems, and strategic importance in global trade, climate regulation, and international relations.
