How do flyways help the Arctic Tern migrate such long distances?
A) Natural formations direct air downward to create a downdraft.
B) Natural formations direct wind patterns and create an updraft.
C) Mountain ranges direct wind patterns that run north to south.
D) Flyways have winds that direct terns along the shortest course.
The correct answer is D) Flyways have winds that direct terns along the shortest course.
Explanation: Flyways are established migratory routes that birds like the Arctic Tern use to travel long distances. These paths are often influenced by prevailing wind patterns that help the birds conserve energy and make their journeys more efficient. By following these wind patterns, the terns can glide and travel along the shortest and most favorable routes between their breeding and wintering grounds.
