Most fossil fuels mined from the sea are mined in coastal areas that make up part of the continental shelf. Very little exploration for fossil fuels is done in the deep sea. What are some reasons for this?
What will be an ideal response?
The most important reason for the limited exploration for fossil fuels in the deep sea is the prohibitive cost of operating in such deep waters. Technology has not been developed that would make such exploration economically feasible. Another factor has to do with the very slim chance of finding oil on the deep sea floor. This is because the oceanic crust, compared to the continental crust, is relatively new and is constantly being recycled in the earth's interior. This means that there is very little time for biological deposits to become covered by many layers of sediment to produce the needed high pressure and temperature for the formation of oil.
