Continents of the World – Formation, Area, Population, Countries & Key Facts
Learn about the Continents of the World, their formation, size, population, and number of countries in one complete GK guide.
Continents of the World
Earth is made up of huge land areas called continents, which together form the main surface of our planet. These continents are not just geographical regions but also represent different cultures, climates, ecosystems, and human civilizations. Understanding the continents of the world is an essential part of general knowledge, geography, and competitive exam preparation.
At present, the world is commonly divided into seven continents. Each continent differs in size, population, number of countries, natural features, and historical development.

Formation of Continents
Millions of years ago, all land on Earth was joined together as a single supercontinent called Pangaea. Over time, due to the movement of tectonic plates, Pangaea broke apart into smaller landmasses. This process, known as continental drift, led to the formation of the present-day continents.
The movement of these plates continues even today, though very slowly, causing earthquakes, volcanoes, and the gradual shifting of continents.
