Manganese nodule

Manganese nodule is a small potato-shaped rocky lump that is found on the bottom of the deep ocean. Picture a small rock you might see outside, but it's dark and covered with bits and pieces of minerals like manganese, iron, nickel, and copper.

This small rock is really important because it's filled with valuable metals that we use to build things like batteries, airplanes, and buildings. Scientists study these nodules to learn more about the ocean and how they form over a long time. They grow slowly over millions of years, just like how you grow taller and bigger as you get older.

It's really hard to get these nodules from the deep ocean because they are so far down, and the pressure is intense. Many countries are trying to figure out how to mine these nodules, but it's a challenge because we want to make sure we're not hurting marine life and damaging the environment.

In summary, a manganese nodule is a small rock-like lump found on the ocean floor that contains valuable metals and helps us learn more about the ocean.
