Question

The three most valuable (in terms of current exploitation) marine physical resources in order from most valuable (1) to least valuable (3) are:

Answer 1

Marine resources are mainly found in oceans and big seas around the world. Biological marine resources include coral reefs, fishes, sponges, crabs fundi and other biological beings. They also include physical resources which are not directly used in various life processes. Some important physical marine resources are- petroleum (oil and natural gas), sand, gravel, methane hydrates, manganese nodules (contains manganese, copper, phosphate, cobalt etc), evaporative salts.

Thus, the three most valuable marine physical resources in terms of current exploitation are (in preference order)-

1. Oil and natural gas (petroleum)

2. Manganese module (also called as polymetallic nodules)

3. Evaporative salts
