Ask the geography teacher to analyze the next question, and kneel down and beg the geography teacher

Answer] c. Analysis: The city of Anchorage is located in the south of Alaska, far from the Arctic Circle, and has a low dimension, so the climate is relatively warm.

As can be seen from the map, Anchorage City is located in the flat land between the mountains, the terrain is flat, and it is close to the ocean and can build a port, whether it is land transportation or sea transportation, it has advantageous conditions, and an important point is that it is close to the continental United States (except the main continent of Alaska and Hawaii), which is convenient for contact and communication with the continental continent; In addition, we can see that the city of Anchorage is surrounded by mountains, which can block the cold air from the north, solid 4 correct. Typhoons are the climatic characteristics of the eastern coastal areas of the Eurasian continent, and the storm surge should be a disaster in the eastern United States, so the entire territory of Alaska is not affected by these two disasters, which is not the reason why Anchorage City is different from other cities. As can be seen from the figure, the southern coast of Alaska is the Alaska Warm Current (from low latitude to high latitude), not a cold current, so 3 is wrong.

The answer is that most of Alaska is located within 60 degrees north latitude, and Anchorage has a subarctic climate (Köppen Climate Classification DFC), but heavier oceans affect moderate temperatures. Winter is susceptible to natural disasters such as cold waves, and there is a warm Alaskan current nearby, which plays a role in warming and humidifying, circle 3 is not right, there is no cold current along the coast, and you will know the choice of C in a comprehensive comparison, the city is on the coastal lowland plain, so circle 4 is also in line with the situation!

c Anchorage has a relatively low dimension, and Coolreich is very well developed by air and is the third largest air port in the world.

Alaska is the largest and least populated state in the United States. Alaska currently has a population of more than 600,000 people, with a population density of square kilometers, and nearly half of the state's population lives in cities. Read the map "Alaska in the United States" (above right), questions 3-4.

3 More than half of Alaska's urban residents live in the city of Anchorage, and the reason for this is the city.

It is not susceptible to disasters such as typhoons and storm surges, and the latitude is relatively low.

The climate is relatively warm.

Located in the interior of the bay, it is less affected by the cold current along the coast, the terrain is low, and the transportation is convenient.

<> are these two pictures? This is a well-known question.

The shadow of the tree faces southwest, indicating that the sun is in the northeast, that is, the sunrise in the northeast. Therefore, the direct sun is in the northern hemisphere, the northern hemisphere is summer, and the southern hemisphere is winter, so the direct sun point should be selected in the southern hemisphere, one is winter and the other is late autumn. According to the contour line, it is judged that water cannot be diverted from artesian water in one place.

First of all, Q1 is low pressure, because only low pressure will bring a front. Because it is summer, there is a lot of convective rain at noon in summer, and after 30-48 hours, it can be calculated that the center of low pressure or the front may control the plutony, so the upward movement of the air flow is more obvious, so there may be strong convective rain. The continuous drizzle is generally brought by a quasi-stationary front and is not distressed, including the low pressure center, and this low pressure center moves very quickly, indicating that the rain generally lasts for a short time and has a high intensity, so it is not right.

There will be no sandstorms in the middle and lower reaches of the Yangtze River. Because it is a center of low pressure, it will not be sunny.

, India is the second most populous country in the world, more than one billion, no matter how low the rate is, it is higher than Vietnam, excluding a, there is no data on the participation rate of men, it cannot be compared with the participation rate of women, excluding b, Japan has the most developed economy, the participation rate is higher than Vietnam, China, Vietnam's economic level is lower than Japan, but the participation rate is high, it cannot be compared, excluding d, the wage level is low, whether it is the employed or the unemployed, the total number of them and the ratio of the population over 16 years old,

As shown in the figure, because the slope is 45 °, in order to maximize the solar radiation, it should be perpendicular to the slope surface, at this time the local sun height should be 45 °, according to the noon solar height formula, the latitude of the direct point can be calculated: 14 °s, according to the direct point moving speed of about 4 days (because of the three-month movement, it can be known that 56 days away from the spring or autumn equinox, it should be d, or use the elimination method, the direct point in the southern hemisphere The time should be between September 23 and March 21, and it can also be determined that it is d, and it is best to use the elimination method for multiple choice questions.

In order to have the strongest solar radiation at noon in place a, it is necessary to make the sun shine as directly as possible, which is possible given that the slope of place a is about 45 degrees.

In order for a place with a slope of 45 degrees to receive direct sunlight, the angle between the sunlight and the ground should also be 45 degrees (the two angles are mutually reinforcing).

Because the latitude of this place is 31 degrees north latitude, in order to make the angle between the solar radiation and the ground 45 degrees, the latitude difference between this place and the direct sun point at that time should also be 45 degrees (or a reciprocal relationship), it cannot be 76 degrees north latitude, but only 14 degrees south latitude.

This time should be between the autumnal equinox and the eastern solstice, so choose D, mid-November.

To add that the angle of solar altitude at a certain latitude at noon is equal to the co-angle of the latitude difference between this place and the point where the sun is shining directly at that time.

For example, if the sun shines directly at the equator, then the angle of the sun's altitude at 40 degrees north latitude is the coincidence angle of the latitude difference of 40 degrees, that is, 50 degrees; If the sun shines directly at 15 degrees south latitude, then the solar altitude angle of 40 degrees north latitude is the coincidence angle of the latitude difference of 55 degrees, that is, 35 degrees.

This theorem is very easy to use.

This has to add up the latitude of 31 north and the slope.

What I said upstairs was right, I used a different method. Draw the earth as one. Now make a tangent at 31 degrees north latitude, and then make a tangent 45 degrees to the north.

The angle between the other side x and the equator is 104 degrees (first calculate the tangent and the equator angle: 90-31=59, plus the slope of 45 degrees, to get 104 degrees). Do the perpendicular line L of x, translate L to the center of the earth, and intersect at point M.

It is known that m is located at 14 degrees south latitude. (180-104 = 76, 90-76 = 14) The sun directly hits 14 degrees south latitude, which can only be d.

In late June, the sun shines directly near the Tropic of Capricorn, when solar radiation is strong.

This question is not that complicated, it mainly asks you about the amount of radiation, and there are two main cases: 1. The Earth is closest to the Sun 2. The direct point of the Sun is in the Northern Hemisphere (n).

The picture is so ugly, I don't want to do it.

The crux of the matter is that the point of direct sunlight should be at a 90° angle to point a, and you can see it at a glance in this way.

A False The upper reaches of the Zambezi River flow through the highlands with a small difference in elevation and a slower current, b Correct Lake Malawi is indeed located in the East African Rift Belt, which has been verified by the Atlas.

cError The midstream is located in the highlands of South Africa.

DFalse The Zambezi River flows through an area between 10 and 20 degrees south latitude, which belongs to the tropical savanna climate, with dry and wet seasons, and the flood season is in January.

The upper reaches flow through the plateau area, and the river slopes gently on the river.

The road is crooked, the water flow is slow, and the swamps along the river are widespread; The middle reaches are also located on the South African plateau, with only the lower reaches of the river area having some plains; The lower reaches of the river flow through the Dien Sang Pec Plain, and the valley widens to 3-8 km. A huge estuarine delta is formed in the vicinity. The Zambezi River Basin is located in the savannah climate zone and the southern hemisphere, and the flood season is in March and April every year. I want to choose C

A is correct, reference.

The Zambezi River belongs to the savannah climate, but it is in the southern hemisphere, so the flood season is in winter, not the month, the Great Rift Valley is in East Africa (extending to West Asia and Israel), and the Zambezi River is in Southern Africa, and the downstream is low-lying and has many tributaries.

b There are many rivers and lakes, and the terrain of Otan can grow many vegetables.

a North-East Plains.

b Increased hazard index.

23aThe area of sandbanks decreased twice in spring and summer, indicating that there were two flood seasons. It belongs to the Northeast River.

The construction of dams in the upper reaches of 24C has impounded sediment, reduced sediment, and slowed down the growth rate of sandbar area.

25d flows from east to west, the north bank is the right bank, find the location of the waterfall, and the downstream of the waterfall is d.

There are no diagrams, just estimates.

First, the sandstone is mainly produced in Yunnan, Sichuan, China, and second, the right bank of the river is seriously eroded along the right bank of the river.

Based on these two points, it should be more or less solved.
