Antarctic Ecosystem and Adaptations

Antarctica is the coldest continent with extreme climate conditions, experiencing long periods of sunlight in summer and darkness in winter. The interior is dry, while the coasts receive more precipitation. Unique phenomena like whiteouts occur due to the uniform snowy landscape. Vegetation is sparse, with mosses and lichens along the coast. The largest land animal is a small wingless insect. Marine life is abundant, with penguins, whales, and krill being prominent. Penguins have unique adaptations for survival. Beneath the ice, there are potential mineral resources, but exploration is challenging due to harsh conditions.
