How many continents touch the arctic circle

There are three continents that touch the Arctic Circle: North America, Europe, and Asia. The Arctic Circle is an imaginary line of latitude located at approximately 66°33′ North, marking the southernmost point of the Arctic, the region of the Earth's surface that encircles the North Pole.

Extra: The Arctic Circle is important because it is one of the five major circles of latitude that mark maps of the Earth. As one proceeds northward from the equator, the circles of latitude are: the Tropic of Cancer, the Equator, the Tropic of Capricorn, the Arctic Circle, and the Antarctic Circle. The area north of the Arctic Circle experiences at least one day of 24-hour sunlight in the summer (the Midnight Sun) and at least one day of 24-hour darkness in the winter (the Polar Night). The continents that extend into these high latitudes are exposed to these unique conditions, which also contribute to the cold climates and the ecosystems found there. The Arctic region is characterized by its unique wildlife, indigenous cultures, and natural phenomena, making it a significant area of study for climate science, biology, and cultural studies.
