The situation of coal, oil and water resources in our country

Answer]: B This question examines the knowledge points such as the separation of China's energy (coal and oil).

Of the four options, Hubei is not rich in coal and oil reserves; Shanxi has large coal reserves, but oil reserves are not abundant; Anhui's oil reserves are not abundant. The correct answer is B.

How is coal and oil formed, and can they be used indefinitely.

In the Paleozoic Era, 40 million to 50 million years ago, there were large forests growing on the earth, and with the movement of the earth's crust, a large number of trees were buried in the ground, which were isolated from the air for a long time, and under high temperature and high pressure, after a series of complex physical and chemical changes to form black combustible fossils, which is the formation process of coal.

Energy resources are in the present.

Socio-economic and technical strips.

It can provide a large amount of energy for human beings and natural processes, including coal, oil, natural gas, wind, rivers, ocean currents, tides, grass fuels, and solar radiation.

Mineral resources refer to the enrichments that naturally occur in the earth's crust or on the surface, are formed by geological processes, are in solid, liquid or gaseous state, and have economic value or potential economic value.

Coal, oil, and natural gas belong to energy minerals.

The rest is energy resources.

There has always been a debate between organic and inorganic theories about the causes of oil. Organic theory holds that petroleum is produced by the proliferation of microorganisms in a certain environment, plus the redox environment, through complex changes. For example, the discovery of China's oil fields such as Daqing Oilfield and Shengli Oilfield is strong evidence for this view.

Inorganic theory is the belief that hydrocarbons are naturally produced in a specific environment. There is currently no strong evidence to support this view. The reason for the survival of coal is recognized as the survival of ancient forest trees after being buried in the ground and undergoing complex geological changes.

In the Paleozoic Era, 40 million to 50 million years ago, there were large forests growing on the earth, and with the movement of the earth's crust, a large number of trees were buried in the ground, which were isolated from the air for a long time, and under high temperature and high pressure, after a series of complex physical and chemical changes to form black combustible fossils, which is the formation process of coal.

Coal and oil are the result of the evolution of animal carcasses and plant residues deep underground over tens of millions of years! It's a long process....

Coal and oil are both non-renewable energy sources on the planet, which take thousands of years to form, and we almost cannot live without them. It is often said that coal is formed from plants and oil is formed from animal remains, is this really the case?

Oil: The raw material is the corpse of living organisms, and the cells of living organisms contain fats and oils, which are composed of three elements: carbon, hydrogen, and oxygen. After the remains of organisms settle on the seabed or at the bottom of lakes and are covered with silt, the oxygen separates and carbon and hydrogen form hydrocarbons.

Coal: The reason for the formation is that the remains of ancient plants are overlapped layer by layer, and after a long period of biological action by bacteria, as well as factors such as crustal changes, environmental high temperature, high pressure, etc., these substances are converted into coal through coalification. In the process of coalification, methane (the main component of natural gas) is also produced, some of which escapes into the atmosphere, and some of which is enclosed in the earth's crust to form gas reservoirs, which is one of the main causes of the dangers of coal mining.

Answer, coal is millions of years of plant branches, leaves and rhizomes, piled up on the ground to form a layer of extremely thick black humus, due to the changes of the earth's crust is constantly buried in the ground, isolated from the air for a long time, and under high temperature and high pressure, through a series of complex physical and chemical changes and other factors, the formation of black combustible sedimentary rock, this is the formation process of coal.

China's forest area ranks 5th in the world, and forest volume ranks 7th. However, China's forest coverage rate is only equivalent to 61 3 of the world's forest coverage rate, the country's per capita forest area is equivalent to 21 3 of the world's per capita share, and the per capita forest volume is only 1 8 of the world's per capita stock.

The current status of forest resources in China is as follows: the forest area is 15,894,100,000 hectares, and the forest coverage rate is 16,55; forest stock of 11.27 billion cubic metres; The area of planted forests in China (excluding Taiwan Province) is 46.667 million hectares, with a volume of 1.01 billion cubic meters, ranking first in the world.

China's coal reserves reached 600 billion tons, ranking third in the world, and oil reserves were about 3.9 billion barrels (it was proved in 1997 that oil reserves ranked eighth in the world.

China's coal reserves reach 600 billion tons, ranking third in the world in China's coal reserves, but the per capita reserves are about 462 tons, far smaller than the world average, the third in the world, and the oil reserves rank eighth in the world.

China's total water resources account for 7% of the world's total water resources, ranking sixth. However, the per capita occupancy is only 2400m3, which is 25% of the world's per capita water volume, ranking 119th in the world and one of the 13 water-poor countries in the world.

China's total oil resources are relatively abundant. According to the statistics of BP in 2003, among the 103 oil-producing countries in the world, China's total recoverable oil resources and remaining recoverable reserves ranked 11th and 10th respectively. By the end of 2003, the proven rate of recoverable oil resources in China was 43, which generally belonged to the medium mature stage of oil exploration.

Based on a comprehensive analysis of the resource situation and exploration potential, it is estimated that in the next 15 to 20 years, China's oil reserves will still be in a period of high and stable growth, and the average annual new recoverable oil reserves will be about 1.4 billion 1.8 billion tons, which will generally maintain the current level of reserve growth.

It should be about the same, and it won't change much in a few years.

How is coal and oil formed, and can they be used indefinitely.

Coal is mainly formed by the burial of plants after a long period of time, while oil is actually formed by the burial of animal and plant remains, but the formation conditions of the two are different, so one will form coal, and the other will form oil.
