At present almost all the metals and industrial minerals utilized to manufacture consumer goods and machinery are extracted from onshore resources. In an effort to become independent of imports and safeguard themselves from future supply shortages, some countries are contemplating mining such resources from the ocean. But underwater mining is still too expensive and there is uncertainty about its environmental impact.
Manganese nodule treasures
> Many thousands of square kilometres of the deep-sea floor are covered by metal-bearing nodules. They contain primarily manganese, but also nickel, cobalt and copper, which makes them economically promising. Although many countries and companies are already intensively investigating their distribution, it is not certain whether the manganese nodules will ever be mined. After all, at least for the intermediate future, there are enough metals available on land.
Metal-rich crusts
> Cobalt crusts are a promising resource on the sea floor because they contain large amounts of cobalt, nickel, manganese and other metals that could exceed the content in land deposits. They form on the rocky surfaces of undersea rises. For their extraction, machines are required that can separate the material from the substrate. To date, however, only conceptual studies exis

The nervous sysyem because i looked it up on the internet. search gal stones effect which body system then but a dash .You will find that it says nervous system.
The cerebellum isn't responsible for coordinating voluntary movements,
There are several techniques that can be used in studying the brain of human beings such as magnetic resonance imaging, magnetoencephalography etc.
Some of the techniques that are used to study the structure of the brain and ita functions are:
- Electroencephalogram (EEG): This is used for the detection of electrical activity in the human brain. It helps in the detection of abnormalities that an individual can have in their brain.
- Magnetoencephalography (MEG): This is a technique that's used for investigating the activities of the human brain. In this test, sensors are used in the formation of an image regarding magnetic fields that are produced within the human brain.
- Magnetic resonance imagining: This is when radio waves that are computer generated and magnetic fields are used in testing the brain. This helps in providing images of the brain.
In conclusion, the above techniques are used in testing the brain in order to carry out further research on the person.
