What if there were no mountains and plains?

If it's all plains, when it rains, there will be water everywhere, and there will be no undulations, and the water will not go away. Cold wave.

Coming, everywhere there was ice and snow, and there was no weakening. Not to mention the change in the climate landscape. It's probably all desert.

It is all plains, and people will have aesthetic fatigue with the natural landscape of the land, and the tourism industry has lost many characteristic tourist attractions. The diversity of species is greatly reduced. Without the melting of snow and ice in the mountains, it is difficult to form rivers.

Typhoons and monsoons without high mountains will penetrate deep inland, precipitation will become widespread, and cold waves will drive deeper south. The world will be affected by a wide range of cold snaps in winter, which will not be conducive to the growth of winter crops and will reduce food production.

If there were no mountains, all plains, then there would be no rivers.

If it is all plains, there is no diversity of flora and fauna, and the natural landscape is very simple.

A plain is a large area with flat or less undulating ground, mainly found on the banks of large rivers and near the sea.

There are two main types of plains: the free-standing plain, which is one of the world's five basic terrain terrains, such as the lower Yangtze River plain. Subordinate plains are the constituent units of a larger terrain, and the plateau can include basins (the Qinghai-Tibet Plateau includes the Qaidam Basin), and basins often have plains and hills of different sizes, such as the Guanzhong Plain, the Chengdu Plain (in the Sichuan Basin) and several plains in the middle reaches of the Yangtze River.

The relationship between basins and plains: some basins include plains, hills and river valleys, such as the Songliao Basin and other basins in several basins to form the Northeast Plain, and the Two Lakes Basin includes the Two Lakes Plain. For example, the North China Plain has part of the Bohai-North China Basin, and the Siberian Plain is the Siberian Basin.

China's three major plains, the world's major plains, the world's main plains.

Plains classification. Stand-alone.

The free-standing plain is a first-class terrain and one of the world's five basic land terrains. The Northeast Plain, the North China Plain, the Lower Yangtze River Plain, and the Western European Plain are all first-class terrains. This plain has a low altitude.

Slave type. A subordinate plain is a unit of larger terrain. Plateaus and large mountain ranges can include basins (the Qinghai-Tibet Plateau includes the Qaidam Basin, the Turpan Basin is between the north and south branches of the eastern Tianshan Mountains), the basins crossed by rivers generally have plains (of different sizes), hills, and valleys, and the bottom of the basin is generally some kind of plain, such as the Sichuan Basin includes the Chengdu Plain, and the Two Lakes Basin includes the Jianghan Plain-Dongting Lake Plain.

The main reason why the earth's surface cannot be very flat is that there are internal geological processes in the earth's interior, mainly including crustal movement, magmatic activity, and metamorphism. The presence of the action of these internal forces causes the surface of the earth to be undulating. Although the external force has always flattened the ground, the internal force is mainly stronger than the external force.

The surface of the earth cannot be all plains.

The plain area has convenient transportation and a well-developed cherry industry; Good air in the mountains.

It should be plain! I live on the plains, and although I would like to live in a place with mountains, because the air is fresh, it feels comfortable, it is quiet and cool, but if the flood breaks out, everything will be bad, will it? Besides, it's not very convenient in the mountains, transportation, shopping, shopping, schooling, etc. are all very difficult, or it depends on your own state of mind, isn't it?

Each has its own merits.

The mountains are prone to mudslides, **, the plateau altitude is high, the air is thin, and there are many sunny days, but the temperature difference between day and night is large, and the temperature is relatively cool in summer.

The plains are prone to flooding, but the terrain is flat, suitable for farming, and there are many rivers, which makes it easy to get water.

At 3:42 a.m. on July 28, 1976, an intensity of the Richter scale (moment magnitude)** occurred in the Tangshan and Fengnan areas of Hebei Province, China, with an epicenter intensity of 11 degrees and an epicenter depth of 12 kilometers, which lasted for about 12 seconds. It caused 242769 deaths and 10,000 serious injuries, ranking second in the number of deaths in the history of the world in the 20th century, second only to Haiyuan.

The terrain is predominantly plain.

The terrain of Qishan is dominated by plains, with mountainous terrain in the north and south.

Qishan is connected to Qinling Mountains in the south, thousands of mountains in the north, the middle is a broad plain, the terrain is inclined from northwest to southeast, the north and south are long and narrow, the east and west are narrower, there are mountains, rivers and plateaus in the territory, the Wei River and the Weishui River pass through, forming the topographic and geomorphological characteristics of "two mountains and one river, two rivers and three plateaus". The highest altitude is 2160 meters, and the lowest is 495 meters.

Poly, from the brand, is a central enterprise, Poly is doing very well in other places, and it is also because many people still don't know much about the reason why they came to Lanzhou last year. There is also ** and the environment is not bad, and it is convenient to go to school in the future. I've seen it, and the middle line road they've planned is already under construction.

I have a few friends who bought it there, and there are quite a few people who buy it, at least not small developers.

If you are in a hurry, you will buy an existing house, and if you are not in a hurry, Poly will hand over the house at the end of next year.

Landlord: Hello.

The blackened places on the moon are plains, not mountains, and these plains are called the Moon Sea. Because the Moon Sea is located in a low-lying area, it reflects less sunlight and therefore appears darker from Earth. The mountains reflect more sunlight, which makes them brighter.

Chopped. The vast majority of the natural communities of the river valley plains are forests. Relatively large plains, such as the Amazon Plain, the Western European Plain, the Bode Plain, the Po River Plain, the West Siberian Plain, the North China Plain, the Northeast Plain, the middle and lower reaches of the Yangtze River Plain, the Pearl River Delta, the Mekong Plain, the southern ...... of the American Great PlainThese native natural communities are all forests.

In Europe, for example, there is a description that a squirrel can jump on a tree all the time from Denmark to Portugal.

Even the valley of the Tarim River was originally a large poplar forest.

Because the flat valley is suitable for agriculture: the land is fertile, easy to irrigate, flat and easy to plant, so a large number of river valley plains are developed into agricultural areas, and of course trees have to be cut down, so the river valley plains appear to have fewer trees. In the undeveloped river valley plains, such as the Amazon and the West Siberian Plain, they are still dominated by forests.

The water source of mountain rivers is the groundwater or ice and snow water rainwater in the higher mountains, with a large drop, rapid water flow, narrow water surface, deep water and abundant water energy; The water source in the plain area is groundwater and seasonal rain, the water flow is slow, the water surface is wide, the water is not deep, and there are many floodplains.

The difference in river bed morphology: the river bed in the mountains is steep and narrow, while the river bed in the plains is wider.

Differences in hydrological characteristics: the water level and flow of rivers in mountainous areas vary greatly, but the duration is short, and the riverbed is mostly bedrock and composed of pebbles; The water level and flow of the plain rivers change little and last for a long time, and the riverbed is mostly composed of fine sand.
