The ocean is known as the blue treasury , what other resources do you know that can be exploited?

1. Marine chemical resources: industrial cooling water, salt and other salts, fresh water, bromine, etc.

2. Marine biological resources: fish, shrimp, shellfish, algae, etc.

3. Marine mineral resources

Continental shelf: oil, natural gas, coal, sulfur, phosphorus;

Coastal placer mine: rich in sand, shells and other building materials, metal minerals;

Ocean basin: deep sea manganese nodules.

4. Marine energy: tidal power generation, wave power generation.

5. Space resources:

Transportation: harbor wharves, submarine tunnels, offshore bridges, submarine pipelines, offshore airportsProduction space: offshore power stations, industrial artificial islands, offshore oil cities, marine ranches Communication power transmission space: submarine cables, submarine optical cables.

Storage space: submarine cargo yard, submarine warehouse, offshore oil depot, marine waste disposal site, cultural and entertainment facility space: marine park, beach, marine sports area.

Marine resources: divided into five categories.

1- Marine chemical resources: such as sea salt, bromine, magnesium, freshwater, etc.

2. Marine biological resources: fish, shrimp, shellfish, algae, etc.

3- Seabed mineral resources: oil, sulfur, phosphorus, the most representative is the deep-sea manganese nodules 4- Marine energy: such as tidal power and wave power.

5- Marine space resources: artificial islands, shipping, submarine warehouses, etc. (the degree of development is still very low).

Shipping, Tidal Energy, Oil, Gas, Combustible Ice

Deep-sea manganese nodules are a variety of ores and potential hydrogen fuel resources.

Mineral, biological, chemical resources.

Because the marine source is rich in resources, there are the following types:

1- Marine chemical resources: such as sea salt, bromine, magnesium, freshwater, etc.

2- Marine biological resources: fish, shrimp, shellfish and algae, no need to give an example3- Seabed mineral resources: oil, sulfur, phosphorus, the most representative is deep-sea manganese nodules 4- Marine energy: tidal power generation and wave power generation.

5- Marine space resources: artificial islands, shipping, submarine warehouses, etc. (the degree of development is still very low).

Guan Xian's statement about protecting the marine resources of the "Blue Brother Elimination Soil" is wrong?

a.Integrated management of marine resources.

b.Improve the enforcement of marine environmental protection.

c.Promote its sustainable use with high technology.

d.Marine resources are inexhaustible (correct answer) Answer analysis: In order to protect the "blue land", we should use high technology to promote the sustainable use of marine resources, improve the law enforcement of marine environmental protection, and implement comprehensive management of marine resources.

The first is that the ocean is blue, because in the vast expanse of the Earth, the land area is about 14.9 billion square kilometres, which occupies only 29 of the Earth's surface, while the ocean covers an area of about 36.1 billion square kilometres, which accounts for 71 of the Earth's surfaceThe ocean is a huge and magical treasure trove for mankind, and there are many treasures that humanity needs.

First of all, the ocean is rich in biological resources. According to surveys, there are hundreds of thousands of species of animals and plants in the ocean, and there are more than 25,000 species of fish alone. There are even more organisms that can be used to refine proteins and antibiotics, amounting to more than 300,000 species.

Hundreds of seafood used in Chinese and Western medicines, as well as drugs such as cod liver oil, proben and insulin, are all derived from marine organisms. Edible aquatic resources can be developed more than 3 billion tons per year without destroying the ecological balance. At present, the annual catch of human beings in Chunjing Prefecture is only 70 million to 90 million tons, less than one-thirtieth of them.

The ocean is also extremely rich in mineral resources. Scientists have discovered that there are more than 80 kinds of elements in seawater, such as gold, silver, copper, iron, aluminum, tungsten, mercury, antimony, oxygen, magnesium, bromine, iodine, rubidium, cesium, nickel, uranium, strontium, etc., and all mineral resources on land are found under the seabed. Scientists estimate that the copper ore in the seabed alone is enough for the world to last 6,000 years; Nickel is enough for 150,000 years; Aluminum is enough for 20,000 years.

At the bottom of the sea, large quantities of oil, coal, sulfur and natural gas have also been found. It is estimated that the total oil reserves of the entire planet are about 300 billion tons, of which 90 billion tons are buried on the seabed, and the continental shelf alone contains more than 100 billion barrels of oil. The seabed is also extremely rich in coal resources.

Currently, 30 percent of Japan's coal production comes from the seabed, Canada's 40 and Chile's up to 80 percentIf all the salt contained in the ocean could be extracted and spread on the land, the ground would increase by nearly 100 meters. In recent years, people have also proved that there are a large number of metal nodule ores on the ocean floor, amounting to more than 40 kinds, among them, the reserves of manganese nodules are 1.5 billion tons, and the Pacific Ocean alone has more than 1 trillion tons, which is thousands of times higher than the reserves on land.

This "resource of the future" has become the "common wealth of mankind".

The turbulent ocean also contains huge energy, only the rising and falling tidal energy, there are about 1 billion kilowatts in the world's oceans, and the tidal energy along the coast of China is about 100 million kilowatts. In addition, there are current energy, wave energy, seawater temperature difference energy, etc. For this reason, the ocean is called the "Blue Coal Sea".

Under the circumstance that land resources are increasingly depleted, the abundant marine resources and ocean energy have brought broad prospects for the material civilization of mankind, and people have turned their eyes to the ocean, and have developed the ocean to different degrees and scales, and have obtained increasingly significant economic benefits.

To sum up, people call the ocean "the treasure trove of blue".

Because the ocean is rich in resources, there are the following:

1- Marine chemical resources: such as sea salt, bromine, magnesium, freshwater, etc.

2- Marine biological resources: fish, shrimp, shellfish and algae, no need to give an example3- Seabed mineral resources: oil, sulfur, phosphorus, the most representative is deep-sea manganese nodules 4- Marine energy: such as tidal power and wave power.

5- Marine space resources: artificial islands, shipping, submarine warehouses, etc. (the degree of development is still very low).

Because the ocean is rich in resources.

First of all, the ocean is blue;

Secondly, the resources on land are close to being exhausted, but the development of marine resources has only begun, and the marine resources are rich and diverse, so they can be called a treasure trove.

Therefore, it has become a "treasure trove of blue".

Because there's a lot of knowledge and a lot of resources in it that we don't know about, and it's blue.
