Nodules

=Nodules =


 * __Nodules__ are potato-shaped rocks, a lump of minerals that is made of oxides of manganese, iron, copper, or nickel and that is found in scattered groups on the ocean ﬂoor. Nodules are formed when minerals get compressed by the ocean's pressure. They have precious minerals inside, they can even have gold or silver inside. They get surrounded by sand that was already there, and when it gets compressed by the ocean's pressure, it gets crystallized, forming a mineral deposit in the bottom of the ocean. They are only found in the deep ocean basins, for example in the abyssal plains. If they are found by the shore, it means it has been moved by waves or the fishes. When you crack nodules in half, you can see the diff erent varieties of minerals inside.

Should you be lucky enough to find nodules on the shore of a beach, do not simply throw it away. Although they might appear as simple rocks, the minerals stored inside can be worth more than you might of originally thought.
