1.Central Asia is rich in water resources, but most of its forms are mountain glaciers and deep groundwater, and their distribution is uneven, coupled with waste and pollution and irrational use, resulting in water shortage. The West Asian region is due to climatic reasons, tropical desert climate, high temperature and little rain all year round, and most of them are located in desert areas without rivers.

2.Most of Central Asia belongs to the temperate continental climate, which is inland, far from the sea, controlled by continental air masses all year round, with little precipitation, arid climate and large temperature difference; East Asia at the same latitude belongs to the temperate monsoon climate, which is caused by the difference in the thermal properties of land and sea, with high temperature and rain in summer and cold and dry in winter.

3.The rainy season is in spring and summer, and the autumn rainy season is in autumn and winter. The rainy season is due to the convergence of cold air from the north and warm air from the north to form a quasi-stationary front, which has similar forces, so it forms a front stay. During the autumn rainy season, the southward retreat of warm and humid airflow is slow, and the cold air has begun to move frequently during this season, resulting in the formation of a large amount of frontal rain.

A1: Central Asia has a continental climate, mostly seasonal glacial meltwater, Central Asia has a large population, and the amount of water resources is large, such as the Syr Darya, Amu Darya, Ili River, etc., all of which have shrunk sharply due to the abuse of water resources.

The Arab region of West Asia has a mostly tropical desert climate, with little precipitation throughout the year.

A2: East Asia has a predominantly monsoon climate, which is obviously influenced by the monsoon, and the annual temperature changes are small, while Central Asia has a continental climate with large annual temperature changes.

A3: The rainy season in Japan and the summer rainfall line in China move to North China at the same time, in August and September, the cause is the same The cold air from the north meets the warm and humid air flow from the south to form a quasi-stationary front Lingering near the Japanese island, it continues to rain a lot.

Thank you for adopting.

Pro: There will be no mudslides far from the mountain, it is convenient for the management of surrounding paddy fields, there is enough drinking water, it is convenient for building water conservancy facilities and transportation, and it is easy to form towns....

Disadvantages: It is not conducive to the development of mixed agriculture and sideline industries, the air humidity is high, and the water, vegetation, etc. are greatly affected by humans, and are easy to be polluted or destroyed....

There are too many pros and cons, let's just talk about these few.

Pros: Because rice cultivation requires constant human management, it will be convenient for people to produce agriculture.

Disadvantages: Rice fields are often irregular, which affects the construction of transportation.

In fact, there are very few villages with such construction, thinking that the disadvantages are greater than the advantages, and the advantages are so justified and the centralized management of rice.

Disadvantages: In this case, I can tell this village very responsibly that when there are some natural disasters, "Tornado,**" is definitely the first to be destroyed and the most vulnerable to tornadoes; Moreover, such a village is prone to water shortage, and such a village can be very hot in the summer and very cold in the winter.

1. There is no necessary relationship between the length of the flow of the river and the large drop, but whether the source of the river is high enough and whether the river water flows into the sea [for example: the flow of the Volga River is many times longer than that of the Po River (in Italy), but the drop of the Volga River is much smaller]; The speed of a river must depend on the size of the drop, which is common sense and is in line with Newton's laws.

2. The map scale is a one-dimensional [straight line], and the map sheet is a two-dimensional [area], you can ponder from their quantitative units (meters, kilometers are linear units of measurement, square meters and square kilometers are the units of area measurement, if it is a measure of water or mountains, you may also use the volume measurement units "cubic meters" and "cubic kilometers").

--These are actually the basics of mathematics and physics!

1. The flow of the river has nothing to do with the terrain difference, and the flow velocity cannot be obtained. The topography of the river should be viewed from the density of the contour line. The denser the contour line, the greater the river drop (in this case, from a particular river segment).

The flow velocity is also seen from the topography difference (which is also the density of the contour line).

2. The scale is magnified by 2 times, that is, the horizontal and vertical coordinates of the map sheet are both x (1+2), then the area of the map sheet is increased to 9 times of the original.

If the scale is enlarged by 1 time, it is equivalent to the horizontal and vertical coordinates of the picture sheet x (1+1), then the area of the map sheet is increased to 4 times of the original.

In summary, your conclusions are all wrong...

1.Yes, the height difference between two adjacent contour lines is the same, and if the flow is long, the horizontal distance is long, then the drop is large.

2.If you magnify it by 2 times, it should be magnified to 2 times before the area of the figure is increased by 3 times.

1. The longer the water flows, the greater the difference, which is the large drop of the river (the drop here is the difference between the source and the estuary)! Whereas, rivers are relatively long, the surface of the earth does not fluctuate much, and the natural flow rate of water is slow.

The second question, upstairs is the right solution!

That's it! Landlord, this is the reason why I emphasize the drop from the source to the estuary after the big drop, and the reason why the topic says that the drop of the terrain is small, it means that the overall topography in the river basin does not change much, and the terrain is relatively flat, so the flow rate of the river is slow!

Choose D, from the wind frequency map, it can be seen that the local northwest monsoon and southeast monsoon are the strongest, and the weakest is the northeast wind, which excludes 1 and 5, because both places are on the Mediterranean coast and have a Mediterranean climate, and the climate is controlled by the subtropical high and the westerly wind belt alternately, even if it is controlled by the westerly wind, it should be a southwest wind, so 1 and 5 are wrong. 3 is located in South Asia, the southwest wind and northeast wind prevail, so it is excluded from the southern part of the Indochina Peninsula, it should be a tropical rainforest climate, there is no prevailing wind, so 4 is excluded. To sum up, choose 6 because 6 is in the southern monsoon belt of China, and the northwest monsoon and southeast monsoon prevail in the monsoon belt of China.

The noon solar height of the Tropic of Cancer on the winter solstice is 90 degrees, indicating that the above is the Southern Hemisphere, t=90 degrees -(& degrees. & =-66 degrees 24 minutes, how can there be no negative value, plus and minus here is relative to the north and south, the southern hemisphere is positive, the northern hemisphere is negative, just in the northern hemisphere.

1.Brasilia has the largest population in the southeast.

2.Temperate oceanic climate (as it should be).

Material 1Tropical rainforest climate.

3.Rising temperatures, rising sea levels, declining species, conservation: reducing forest exploitation, improving living conditions for local populations, increasing revenues to reduce forest exploitation, and accelerating energy development.

That's it, and if you have time, I'll be able to help you find it.

At noon on the winter solstice, the height of the sun decreases from the Tropic of Capricorn to both sides. In the Arctic Circle, the sun is at 0 degrees at noon. The North Pole is supposed to be -23 degrees 26 minutes, but geographically everything below 0 degrees at noon is counted as 0 degrees.

The solar altitude angle changes with the rotation of the earth, and on the winter solstice, the sun hits the Tropic of Capricorn directly, and the solar altitude angle in the northern hemisphere reaches its maximum, and the solar altitude angle is greater than zero degrees at any time.

Excessive population growth will increase the pressure on the natural environment, excessive and irrational exploitation of natural resources, leading to the deterioration of the climate and the deterioration of the environment (air pollution, water pollution, etc.), resulting in an increase in diseases; High social pressure (housing shortage, traffic congestion, medical pressure, etc.); rising crime rates; It is not conducive to the sustainable development of the economy.

China's population is in the stage of low birth rate, low mortality rate and low growth rate, but China's population base is large, and a large number of people are born every year. The largest number of Chinese population is 1.6 billion, and after reaching 1.6 billion, the population will decline.

When the world's population grows rapidly, it leads to housing shortages, resources shortages, employment tensions, and the destruction of the environment accelerates.

When the world's population growth slows down, it will lead to low demand, sluggish economy, and great pressure on social security, and the trend of China's population growth is low mortality rate, low birth rate, high growth, and high growth due to China's large population base.

1.The world's population problems will have a big impact, with housing shortages, traffic congestion, employment difficulties, and even food and water shortages.

2 China's population is growing rapidly, but it will decline slightly in the next few years.

Population issues have a huge impact on society, such as; Housing is tight, traffic is congested, and employment is also difficult when the population is large.

For the economy, the per capita economy is less, there are more poor people and fewer rich people.

The trend is that the Earth's population grows to 10 billion and then it comes down.

I'm a master, I don't do this manual work, I search the Internet by myself, it's easy to find.

The Jianghan Plain is a plain formed by the alluvium of the Yangtze River and the Hanjiang River, located in the middle reaches of the Yangtze River The Hetao Plain usually refers to the plain along the Yellow River in the middle of the Inner Mongolia Plateau, west to Helan Mountain, east to the east of Hohhot City, north to Wolf Mountain, Daqing Mountain, and south to the Ordos Plateau. The plain mainly belongs to the Yangtze quasi-platform Jianghan and the Han Dynasty, the terrain is low and flat, except for the gentle hill with an altitude of about 50 meters and a low hill of more than 100 meters at the edge, the altitude is below 35 meters. It is generally slightly inclined from northwest to southeast, the elevation in the northwest is about 35 meters, and the southeast drops to less than 5 meters, and Hankou is only 3 meters.

The plain is dotted with lakes, intertwined water networks, and embankments are vertical and horizontal. The surface material is mainly composed of modern river alluvium and lake silt, which belongs to fine sand, silt and clay, and the Tertiary red beds are only exposed in the edge of the plain. Here the Yellow River first flows northeastward, then turns to the east, and then turns to the south, forming a horseshoe-shaped bend, called the Hetao.

The plain is formed by the alluvium of the Yellow River and its tributaries. It stretches along the Yellow River from east to west, with a length of 500 kilometers and a width of 20 90 kilometers from north to south. It covers an area of about 10,000 square kilometers.

The Hetao Plain is 900 to 1200 meters above sea level, the terrain is slightly inclined from west to east, and the Quaternary sedimentary layer in the northwest is more than 1,000 meters thick. The front of the mountain is a flood plain, accounting for 1 4 of the total area of the plain, and the rest is the alluvial plain of the Yellow River. The surface is extremely flat, and the slope drop is mostly 1 4000 1 8000, except for the large slope in the piedmont flood plain.

It can be divided into 3 parts: the east of Helan Mountain is called Yinchuan Plain, the south of Wolf Mountain is called Houtao Plain, and the south of Daqing Mountain is called Tumochuan Plain (Qiantao Plain.

ParseOn the winter solstice, the shorter the day length and higher latitude in the Northern Hemisphere, and the longer the day length and higher latitude in the Southern Hemisphere; The closer you get to the equator, the closer you get to the equator. Then in the question, A and B are in the northern hemisphere and latitude A and B, C is closer to the equator, and D is located in the southern hemisphere.

Have you ever considered the real war, it is not that 70w people charge together must be powerful, after all, when the fight starts, only the front part of the people can fight with the other party, and the people in the rear have to continue to rush forward, which is actually equivalent to reducing their own strength to a minimum (can be combat at the same time), and, when the troops charge, the front team has begun to engage the enemy army, and the rear team is still continuing to rush forward, which is also easy to cause the rear army to trample on the front army. It is equivalent to killing nearly half of his own troops first. In addition, in ancient warfare, it was important to divide troops and attack in a short distance (which was also a way to lengthen the front line to maximize the number of troops engaged in battle at the same time), and echoed from afar (it was possible to attack the enemy's lineup from many sides and pick out the weak underbelly). And the garrison is in one place, undoubtedly limiting their own strength at the same time limiting their own action, although the numbers are scary, but in fact it is easy to be annihilated by the other party in one fell swoop.

As mentioned in the sect, in addition to excluding the conditions for burning the company camp, it is still taboo for soldiers to station troops in one place.

The use of soldiers not only pays attention to combat power, but also how long does it take to communicate from the beginning to the end of 700 miles? If the military situation should be reported inside, the 700-mile army will charge forward in front, and the rear will not be able to make up for the chaos in time, so that the 70w army will be divided into multiple parts, and then break them one by one, which is not a difficult thing. This is one of them.

Second, 700 miles, the soldiers in front can be short-handed, and the later can be crossbowed, and then the bow, so what to do later? The 700-mile long formation is like a wave of troops, the troops are scattered, the attack power is low, and it is a siege, and the 700-mile long array of soldiers attacks at once, how can there be a chance of victory?

Thinking about the Battle of Chibi, why did Pang Tong plot to connect Cao Aman's ships together? Because as long as they are connected together, the fire can be burned, and it is also taboo for Liu Bei to connect the battalions together, so that whether you are in a dense woods or an open place, as long as the enemy attacks with fire. Defeated.

I'm just a passerby, I just want to know that 700 miles is a taboo, so is 500 miles a taboo?
