Which outcome results when timber bridges constructed by Viking expeditions experienced prolonged saturation in Northern Atlantic voyages?

💡 Explanation

Prolonged saturation leads to decomposition by anaerobic bacteria because the timber cells are deprived of oxygen, therefore anaerobic bacteria proliferate, rather than aerobic decay or corrosion, which needs oxygen and specific metallic components.
