The largest continent by area on Earth is Asia. Covering approximately 44.58 million square kilometers (17.2 million square miles), it accounts for about 30% of the Earth's total land area. Asia is incredibly diverse geographically, culturally, and biologically, and it is home to the highest population of any continent, including vast countries like China and India. Its rich history, natural resources, and varying landscapes, from deserts to mountain ranges, make it a significant region in global economics and politics.
