Continents are large landmasses that are typically defined by their distinct geographical, cultural, and ecological characteristics. There are seven recognized continents on Earth: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Each continent has its own unique features, including diverse climates, ecosystems, and populations. The concept of continents is essential for understanding global geography and human civilization. They play a crucial role in shaping the world's cultures, economies, and environments. For instance, Asia is known for its vast population and rich history, while Africa is recognized for its biodiversity and cultural heritage.
