The largest seasonal change in water level in China is which of the four major regions has a score o

The North Bar has the influence of ice melt and rainfall from the northwest in the summer.

In the winter, there was no rain, and there was no precipitation, and the water level dropped.

To use an analogy, the highest water level in the north is rain, plus iceberg, and the water level is 1+1, and the lowest water level is 0

And the northwest is 1 only iceberg and rain is negligible.

2-0 is greater than 1-0

So it's the North.

In the northern region, the reason is that the landlord said that the monsoon, there is less rain in winter and more rain in summer.

Summary. Hello, it is a pleasure to serve you. I am a special guest to answer the main sister Xie Xue**, a senior teacher in an educational institution, with five years of work experience, a total of 6,000 people, it takes a few minutes to reply, please be patient.

You're a good model, and it's a pleasure to serve you. I am a special guest to answer the main Xie Xuejie** answer, a senior teacher in an educational institution, with five years of work experience, a total of 6,000 people, it takes a few minutes to reply, please wait patiently.

Hello, the upstream is subject to seasonal changes, and the upstream changes more than the upstream.

I really hope that I can help you, and I wish you a happy life and a happy day. Why is the runoff mentioned here changing so much upstream?

What's going on?

What I said above is also a pro with big changes in the upstream.

Look closely. Whew.

Whew. Excuse me.

Excuse me.

Answer]: C Examination Points] This question examines the knowledge points such as the characteristics of the water ridge of the main river cherry and the ant trapped in China.

Among the four rivers of the Pearl River, the Yangtze River, the Yellow River and the Min River, the Yellow River mainly flows through the northwest and northern regions, and the seasonal change of water level is the largest, and the flood season is the shortest.

Influencing factors: recharge type - precipitation (seasonal variation); The amount of groundwater, the amount of tributaries, and the area of the basin.

Natural loss mode: evaporation, infiltration.

Topographic vegetation. Human activity.

Water level refers to the elevation of the free water surface relative to a certain base surface, and the distance between the water surface and the bottom of the river is called the water depth. The base surface used to calculate the water level can be the zero level base surface with a certain characteristic sea level elevation, which is called the absolute base surface, and the base surface of the Yellow Sea is commonly used. It is also possible to use the elevation of a specific point as the zero point of the reference to calculate the water level, which is called the base surface of the station.

Water level is the most intuitive factor reflecting the water condition of the water body, and its change is mainly caused by the increase or decrease of the water volume of the water body. The water level process line is the curve of the water level at a certain place as a function of time, with the horizontal coordinates being the time and the vertical coordinates being the water level.

The large seasonal difference in water level in the lower reaches of the Yellow River is mainly due to the large seasonal variation of precipitation in the middle and lower reaches of the Yellow River. The middle and lower reaches of the Yellow River have a temperate monsoon climate, with precipitation concentrated in summer and little precipitation in winter and spring.

Good luck with your studies!

Answer] B Answer with stupid analysis] Test question analysis: According to the basic law of the rain belt moving from south to north in the eastern part of China, the more rivers in the northern region, the greater the seasonal change of the water level of the flow, and the lower the flood season, so in the comparison options, the Yellow River is located in the northernmost part, so the flood season of the river is the shortest.

Test Center: This question examines the changes in rivers and precipitation in our country.

Comments: The difficulty of this question is low, and students only need to grasp the regional distribution law of precipitation in eastern China, and then judge the impact on river flow.

Answer B: In the above answer, the Brahmaputra River is mainly fed by glacial meltwater, the Pearl River and the Yangtze River are located south of the Huai River in the Qinling Mountains, and the rainy period is longer, so its flood season is also very long, only the Yellow River is in the north, which is greatly affected by the rain and the affected time is also very short.

Answer B In Zheng's answer above, the Yaparot Luzangbo River is mainly fed by glacial meltwater, the Pearl River is located in the south of the Qinling Mountains and the Huai River, and the rainy period is long, so its flood season is also very long, only the Yellow River is in the north, which is greatly affected by the rain and the affected time is also very short.
