Information about various terrains, what are the descriptions of terrain and topography

Describe the topography of the terrain

Topographic type (plains, mountains, hills, plateaus, basins, etc.), typical terms: terrain is the main thing. types and pins.

Relief conditions, terrain inclination direction and trend, regional extremes (highest and lowest values of terrain).

Typical expressions: high direction, low direction.

under a variety of terrain conditions) main terrain distribution, spatial arrangement.

Elevation conditions, important topographic profile features (in profile).

The five prominent terrains are plains, plateaus, hills, basins, and mountains, all of which have different levels except for plateaus. There is a distinction between primary and secondary types of these terrains. They are different from each other in the morphology of their adjacent siblings, and the meaning of adjacency itself excludes inclusion, for example, the Sichuan Basin is surrounded by plateaus and mountains.

Mountains: high altitude, generally above 500 meters, with undulating peaks and steep slopes; Plains: low altitude, generally below 200 meters, flat and broad surface; Plateau:

The altitude is high, the ground is flat or undulating, and the edge is steep; Hills: low altitude, not much undulation on the surface, gentle slope; Basin: high on all sides, low in the middle.

14. Characteristics of the five basic terrains:

Plains: low altitude and flat ground;

Plateau: high altitude, flat ground with steep edges;

Mountains: high altitude, undulating peaks and steep slopes;

Hills: the ground is undulating, the altitude is not high, and the slope is gentle;

Basin: high in the periphery and low in the middle.

Five basic terrain types.

There are many types of terrain, but there are generally five types of basic terrain:

1. Plains

Plain terrain refers to flat and open areas below 200 meters above sea level, generally distributed along rivers and coastal areas. The largest plain in the world is the Amazon plain. China's three major plains are the Northeast Plain, the North China Plain, and the Middle and Lower Yangtze River Plain.

2. Hills

Hilly terrain refers to an area with an absolute height of less than 500 meters, a relative height of no more than 200 meters, and a certain undulating slope. The largest hill in the world is the Kazakh Hills. The main hills in China are Shandong hills, Liaodong hills, and southeast hills (including Jiangnan hills, Liangguang hills, and Zhejiang-Fujian hills).

3. Mountains

Mountain terrain refers to the highland above 500 meters above sea level, with great undulations, steep slopes, deep valleys, and generally vein-like distribution. Mountains vary in size and can be divided into high, medium, and low mountains according to their height. Those above 3,500 meters above sea level are called high mountains, those with an altitude of 1,000-3,500 meters are called middle mountains, and those with an altitude of less than 1,000 meters are called low mountains.

The highest mountain range in the world is the Himalayas, and the largest mountain system is the Cordillera mountain system.

Fourth, the plateau

Plateau terrain usually refers to a relatively complete large-scale uplift area with an altitude of more than 1,000 meters above sea level, a vast area, an open terrain, and a relatively complete area of uplift bounded by obvious steep slopes. Of course, in reality, some plateaus are less than 1,000 meters above sea level, such as the Deccan plateau, which has an average altitude of 500-600 meters. The highest plateau in the world is the Tibetan Plateau.

5. Basin

The main characteristics of the basin topography are high around and low in the middle, so it is named because of the basin shape, and there are no specific elevation requirements. The largest basin in the world is the Congo Basin. China's four major basins are the Tarim Basin, the Junggar Basin, the Qaidam Basin, and the Sichuan Basin.

A map of China refers to a map drawn to clarify the territory of China. China is located in the east and central part of Asia, on the west coast of the Pacific Ocean, and is a country with both land and sea on its back. The land territory includes the mainland of the People's Republic of China and its coastal islands, Taiwan and its affiliated islands, including the Diaoyu Islands.

The width of the territorial sea is 12 nautical miles from the baselines of the territorial sea, and the width of China's contiguous zone is 24 nautical miles. The total area of the country is 9.6 million square kilometers.

Geographical location. China is located in eastern and central Asia, on the west coast of the Pacific Ocean. The tip of the Chinese border is located at the northernmost point of the Heilongjiang main channel north of the Mohe River in Heilongjiang Province (53°.

The southernmost point is in the Spratly Islands in the South China Sea, in the Tsangmu Dark Shoal (3 degrees 58 minutes 00 seconds N, 112 degrees 17 minutes 00 seconds east longitude.

Spratly Islands. The Herald Reef and Sierra Reef in the Spratly Islands are about 70 kilometers south of them.

It is about 50 km north of Tanjong Payong in Malaysia.

Indonesia's Natuna Islands are about 400 kilometers to the east.

The city of Niah in Borneo is about 120 km west [1].

The easternmost and easternmost point is at the Black Blind Island in Heilongjiang Province (the intersection of the center line of the main channel of the Heilongjiang River and the Ussuri River) (48°27 N, 135°05 E).

The westernmost and westernmost point is on the Pamir Plateau in Xinjiang, about 25 kilometers southwest of the intersection of the borders of China, Tajikistan and Kyrgyzstan, where there is a snow-capped peak with an altitude of more than 5,000 meters. (39°15′n、73°33′e）。

The northernmost point of Chinese territory is on the center line of the main channel of the Heilongjiang River north of Mohe in Heilongjiang Province (53°N).

The north and south are far apart.

The above is a topographic map of China and an administrative map of China.

Knowledge points: China has 34 provincial-level administrative units, including 23 provinces, 5 autonomous regions, 4 municipalities directly under the central government, and 2 special administrative regions.

You're looking at this, aren't you? I've forgotten what a topographic map is, it's been so many years since I graduated.

With Google Earth, you can see it all over the world.

The topography of a place can be determined by the elevation of the place and the size of the slope of the surface. For example, a mountainous area is a terrain with large undulations below 500 meters above sea level.

The topography is the topography of the place, such as the first line of heaven and the Loess Plateau, etc.

The climate of a place can be considered in terms of precipitation and temperature, for example, the tropical rainforest climate is hot and rainy all year round.

There are three steps to describing the topography:

1. Briefly describe the landform (e.g., high in the east and low in the west).

2. Describe the terrain (e.g., plains, plateaus, mountains, etc.).

(1).Terrain type.

2).The terrain is undulating.

3).The main topographic distribution, spatial arrangement.
