What is the larges landmass?

Answer 1

The single largest mass of continuous, non-interrupted land on planet earth is the EurAsian supercontinent, a massive duo-continent that extends from the Russian Siberia coast on the Bering Strait (near Alaska) on the extreme east to Cape Roca (Cabo de Roca) Portugal, on the Atlantic, on the west. The size of EurAsia is 20.8 million square miles. The second largest is the American supercontinent, which also extends from the Bering Strait, Cape Prince of Wales in Alaska south to Cape Froward on the southern tip of the South American country of Chile.
