Crescent-shaped Indus Plain

Plain refers to the landform with relatively flat ground, small undulating slope and wide area. Plain soil is fertile, easy to cultivate, humid in temperature, easy to live, flat in address and convenient in transportation. This plain is a fertile land. So, now let the urban culture show us the elegance of the top ten plains in the world.

brief introduction

The Indus Plain is located between India and Pakistan, and most of it is the vast thar desert. The irrigation agriculture along the Indus River is developed, and it is one of the main population gathering areas in Pakistan. The Indus plain is flat and wide, with 300 meters thick alluvium. The coastal plain is the birthplace of Indian civilization, with developed agriculture, dense population and cities everywhere. The estuary delta covers an area of about 57,000 square kilometers, with dense river networks and fertile soil. It is an economically developed area in Pakistan. The two plains are connected, the slope is very small, and the middle watershed is only 250 meters.

One of the largest alluvial plains in the world. It covers an area of 266,000 square kilometers. Extending from the Himalayas in South Asia to the Arabian Sea. The Indus Plain is the economic and cultural center of Pakistan, with a population of about four-fifths of the country. Rich in wheat, rice, cotton and so on. Kotri, Sukur, Gudu, Dangsa and Jinnah all have large-scale irrigation projects. Cities with a population of over 500,000 include Karachi, Lahore, Layapur, Hyderabad and Multan. The railways and highways are densely covered and the traffic is developed.

Located in South Asia, it is a rich and fertile ancient land. The plain is roughly divided into three parts: the Indus valley in Pakistan, the Punjab and Haryana plains, and the middle and lower reaches of the Ganges. There are two major water systems, Ganges River and Indus River, which span India, Pakistan and Bangladesh, covering northeast India, the most densely populated area in Pakistan and most parts of Bangladesh. It is one of the most densely populated areas on earth, with more than 100 people living there. One of the largest alluvial plains in the world.

climate

It belongs to subtropical grassland climate, subtropical desert climate and tropical monsoon climate.

geographical position

It covers an area of 266,000 square kilometers. It extends from the foothills of the Himalayas in southern Asia to the Arabian Sea, with a length of 65,438+0,280 km from north to south and a width of 320-560 km from east to west. It is customary to divide the upper and lower Indus plains by the line of 29 north latitude. The former is Punjab plain, and the latter is Sindh plain and delta area. The ground inclines from north to south and is located in Pakistan, India and Bangladesh in the north of South Asia.

It is alluvial by the Indus River, Ganges River and Brahmaputra River, also known as the Great Plains of India. It is crescent-shaped, extending from the Indus Valley in Pakistan to the Punjab Plain and from Haryana Plain to the Ganges Delta in Bangladesh. It is covered with cliffs, and the basic geomorphological features of the plain are formed by river erosion and river course change.

In the north, two long and narrow Wright plains form the northern edge of the central plain, and the groundwater flowing from the foothills of the Himalayas forms a swamp around the rivers in the plain. In the south, the mountains and central highlands extending eastward from Rajasthan along the Indian desert extend to the Bay of Bengal, forming the southern edge of the plain. The elevation of the mountain ranges from 300 meters to 1200 meters, which is roughly east-west.

resources

The Indus Plain is the economic and cultural center of Pakistan. The main crops are rice and wheat, and the other main cash crops are corn, sugarcane and cotton. The southwest monsoon brings enough rain to crops, making this area less dry, and the Himalayas provide enough irrigation water for this area.

mountain range

Himalaya is Sanskrit, meaning "hometown of snow", and Tibetan is called "snow mountain". Located at the southern tip of the Tibetan Plateau, it is an approximately east-west mountain system, with the main part at the junction of China, Nepal and India, with a total length of 2,400 kilometers, a width of about 200-300 kilometers and an average elevation of over 6,000 meters. There are many peaks around, of which more than 50 are over 7000m, and 10 is over 8000m. Mount Qomolangma, the highest peak in the world, is 8844.43 meters above sea level, and stands on the border between China and Nepal in the middle of the Himalayas.

The southern slope of the Himalayas is steep and the northern slope is gentle. The southern slope is 6000-7000 meters higher than the Ganges and Indus plains, which constitutes a huge natural barrier. Because the southwest monsoon of the Indian Ocean was intercepted, there was abundant precipitation and the snow line on the mountain was low. "Everest" is Tibetan, meaning "the third goddess". It is the main peak of the Himalayas, with an altitude of 8844.43 meters, the highest peak in the world, and is also known as the "roof of the world" with the South Pole and the North Pole.

The northern slope of Mount Qomolangma is in Dingri County, Xigaze Prefecture, Tibet, China, and the southern slope is in the Kingdom of Nepal. A white cloud belt can often be seen at the top of Mount Everest, just like a flag fluttering in the wind, so it is called "Yun Qi" and foreign explorers call it "the veil of the Virgin". Observing the shape of Yun Qi can accurately predict the weather change of Mount Everest. Therefore, some people call "Mount Everest in Yun Qi" the highest weather vane in the world.
