Mentally handicapped geography problem 30 points bounty

1.Physically, we have the term thermal expansion and cold contraction. The same principle applies to air. The main reason for the occurrence of thermal circulation is the uneven distribution of air.

In hot places, the air expands and rises, causing the air on the ground to become thinner and form a zone of low pressure. In cold places, the air is affected by gravity and sinks, creating a high-pressure zone. Therefore, the high-pressure area is colder.

Pressure cookers are different. The reason why the pressure cooker becomes high pressure is that it is in the same large volume, and the pressure in the pot is constantly increasing due to the continuous expansion of gases. High pressure in a pressure cooker refers to an increase in pressure caused by the squeezing of gas in the pot.

2.We all know that land is made of soil. And the specific heat of water is greater than that of soil.

During the day, after absorbing the same temperature, the land heats up faster than the water, and the heat expands and contracts, so the air on the continent rises, and a low pressure zone appears on the ground. Conversely, high-pressure bands appear on the surface of the water. When a zone of low pressure appears on the ground, the surrounding high pressure flows over to replenish the area of low pressure.

Thus a blowing sea breeze is formed (the wind is formed due to the movement of the atmosphere); At night, the land cools down faster than the water, so the temperature on the ground is a bit lower than on the water. The air on the water surface will be heated and rise, and low pressure will be formed, and the land will form a high pressure zone. The atmosphere in the high-pressure area moves towards the low-pressure area, forming wind, so it is generally a land wind at night.

1.Because the pressure cooker has to be heated before it can be used. So the heat in the pressure cooker.

2.The temperature is not the same during the day and at night.

High ground temperatures cause airflow to rise, creating high pressure.

During the day, the land temperature is higher than the water.

At night, the land temperature is lower than the water.

That's why the diurnal thermal cycle is different...

And ah... You really need to do a good job of tutoring geography.

1 Have you ever heard of cold shrinkage and thermal expansion?!

Heat: The gas expands and rises when heated, and the ground is at low pressure at this time;

Cold: The gas shrinks and sinks when it is cold, and the ground is under high pressure at this time.

2 It is related to the specific heat capacity.

Have you ever been to the beach? Let's walk barefoot by the sea.

During the day, the sand on the beach is very hot, and the sea water is very cool, and at night, the sand on the beach is colder than the sea, and the sea water seems to be warm, which is the problem of specific heat capacity.

So. Daytime: Warmer on land and cooler at sea.

Night: Cooler on land and warmer at sea.

High pressure means that there is a lot of air there (pressure is related to the amount of air), and the air density is low in hot places and dense in cold places, so cold places are high pressure.

The heat has to be circulated, and its power is solar energy, so it is different during the day and at night.

It's easy, it should be easy to understand.

Hot. The specific heat capacity is not the same, so the air pressure is different.

Generally, it is an anticlinal oil store. Most of the oil in the north is in the anticline basin.

Most of China's recoverable oil resources are distributed in plains, shallow seas, Gobi and deserts, which are specific examples I found on the Internet, you can refer to them.

1. Onshore: Northeast: Songliao Basin (Daqing Oilfield, Liaohe Oilfield, Jilin Oilfield) North China: Bohai Bay Basin (Shengli Oilfield, North China Oilfield, Dagang Oilfield, Jidong Oilfield) Northwest and Southwest:

Sichuan-Shaanxi Basin (Southwest Oilfield, Changqing Oilfield), Xinjiang, Qinghai: Tarim Basin (Tarim Oilfield), Karamay Oilfield, Qinghai Oilfield, Tuha Oilfield, etc.

Central China: Zhong**tian, Henan Oilfield, Jianghan Oilfield, etc.

2. Offshore: Bohai Sea: Penglai 19-3 oilfield.

East China Sea: Chunxiao and other oil and gas fields.

South China Sea: Yinggehai Basin.

China's petroleum resources are concentrated in the eight major basins of Bohai Bay, Songliao, Tarim, Ordos, Junggar Basin, Pearl River Estuary, Qaidam and East China Sea Shelf, with recoverable resources of 17.2 billion tons, accounting for the country's total. Natural gas resources are concentrated in the nine basins of Tarim, Sichuan, Ordos, East China Sea Shelf, Qaidam, Songliao, Yinggehai, Qiongdongnan and Bohai Bay, and its recoverable resources are trillions of cubic meters, accounting for the country's total.

From the perspective of geographical distribution, 76 of China's recoverable oil resources are distributed in plains, shallow seas, Gobi and deserts, and 74 recoverable natural gas resources are distributed in shallow seas, deserts, mountains, plains and Gobi.

Structurally speaking, the anticline is a good oil storage structure.

Hope it helps.

There is a lot of oil in the plains and plateaus, but there is no oil in the mountains and hills.
