Explain the word 'Continent'.

A continent is a large continuous mass of land conventionally regarded as a collective region. Continents are typically defined by geographical, cultural, and historical factors. There are seven commonly recognized continents on Earth: 1. **Asia** - the largest continent, known for its diverse cultures, languages, and landscapes. 2. **Africa** - the second-largest continent, rich in natural resources and cultural diversity. 3. **North America** - includes countries like the United States, Canada, and Mexico, known for its varied geography and climate. 4. **South America** - known for the Amazon rainforest and Andes mountains, with a rich cultural heritage. 5. **Antarctica** - a largely uninhabited, ice-covered continent at the South Pole. 6. **Europe** - known for its historical significance and cultural diversity, often considered a cradle of Western civilization. 7. **Australia** - the smallest continent, often referred to as Oceania when including the Pacific islands. Continents are significant in terms of ecology, geology, and human geography, influencing climate, biodiversity, and human activities.
