Final answer:
The Navigation chart from Marshall Islands, Micronesia in 1890 C.E. made of wood and fiber was used for navigation at sea by representing ocean swells and currents.
Step-by-step explanation:
The function of the Navigation chart from Marshall Islands, Micronesia in 1890 C.E., made of wood and fiber, was to aid in navigation at sea. These charts, also known as stick charts, were used by Polynesian navigators to represent ocean swells and currents, helping them to navigate their way through the open waters.
The wooden framework of the chart represented the major currents and wave patterns, while the fiber strands connecting the framework represented the smaller waves and ripples. By observing the movement and interactions of the sticks and strands, navigators could determine their position and find their way.
