Adak Island, a small island in the Andreyanov Group of Aleutian Islands, is 80 kilometers long from east to west and 40 kilometers long from north to south. The island is located in the middle of the Aleutian Islands, and Andreyanov Island Group is a part of the Aleutian Islands, which consists of two largest islands, Atka Island and adak Island, and several surrounding islands. The original indigenous people of the Aleutian Islands are Aleutians, belonging to a branch of North American Indians. They live by fishing and hunting seals. 1724, Peter the Great of Russia entrusted Vitus Bering, a Danish, to explore the land east of Siberia for Russians, and discovered the Bering Strait in 1728. Later, Russia expanded eastward, crossed the Bering Strait and occupied today's Alaska and its island Aleutian Islands. Later, Russians began to settle in the Aleutian Islands, mainly engaged in killing whales and seals. Although the latitude of Aleutian Islands is high, it is not very cold in winter and the temperature is not high in summer due to the influence of the North Pacific circulation. The climate of the islands is influenced by Alaska warm current and polar ocean air mass. In winter, it is foggy, snowy and windy. There are no trees on the island because of the strong wind. The islands formed by volcanic eruption are all over the cliffs, and moss is the main plant here.
