There are seven continents on Earth: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. Each continent is distinct in terms of culture, geography, climate, and biodiversity. Asia is the largest, both in area and population, while Antarctica is the least populated and covered primarily by ice. Each continent hosts unique ecosystems and significant natural resources, contributing to the planet's ecological diversity. The concept of continents varies slightly depending on regional perspectives and cultural contexts, but globally, they are recognized as the primary landmasses of our planet.
