Answer:
Manganese nodules are deposits of ferromanganese oxides and other elements in the soil of the oceans.
Step-by-step explanation:
Manganese nodule is the name given to the deposition of ferromanganese oxides and other elements in the soil of the oceans. These nodules vary in size from 1cm to 10cm in size and distribution in the oceans, being formed by three different types of accretion, most of which are complementary. The main features of the internal structure are the presence of concentric layers of varying sizes, possibly due to different growth rates, and cracks or cracks that can cause decomposition in the ocean floor.
