Africa

Africa is the world's second-largest and second-most populous continent, after Asia in both aspects. At about 30.3 million km² including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area. With 1.4 billion people as of 2021, it accounts for about 18% of the world's human population.

Antarctica

Antarctica, the southernmost continent and site of the South Pole, is a virtually uninhabited, ice-covered landmass. Most cruises to the continent visit the Antarctic Peninsula, which stretches toward South America. It's known for the Lemaire Channel and Paradise Harbor, striking, iceberg-flanked passageways, and Port Lockroy, a former British research station turned museum. The peninsula's isolated terrain also shelters rich wildlife, including many penguins

Asia

Asia is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometers, about 30% of Earth's total land area and 8% of Earth's total surface area.

Australia

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. Australia is the largest country by area in Oceania and the world's sixth-largest country.
