A few geography questions for the first year of junior high school!!! A few geography questions in j

The general topography of Europe is characterized by plains, glacial landforms are widely distributed, high mountains and mountains converge in the south, plateaus, hills and mountains above 200 meters above sea level account for about 40% of the total area of the continent, of which only 15% are above 500,000 meters above sea level, and only about 2% are high mountains above 2,000 meters above sea level; Plains below 200 meters above sea level make up about 60% of the continent's area. The average altitude of the whole continent is 300 meters, which is the lowest average altitude of the continent. The European Plain stretches for thousands of miles from the Atlantic coast in the west to the Ural Mountains in the east, forming a great plain across Europe.

The Alps stretch to the south and are the largest mountain range in Europe. Mount Elbrus, the main peak of the Greater Caucasus Mountains in the southeast, is 5,642 meters above sea level, making it the highest peak in Europe. Scandinavia's mountainous terrain in northern Europe is relatively gentle, with steep fjords running deep inland.

The lowlands along the northern coast of the Caspian Sea are 28 meters below sea level, the lowest point on the continent.

Most of South Asia is located at low latitudes, that is, between 30°N latitude and the equator, and the Tropic of Cancer runs through the central part of South Asia; South Asia is surrounded by the sea on three sides and traverses the Himalayas to the north.

Refers to the southern region of Asia. These include Sri Lanka, Maldives, Pakistan, India, Bangladesh, Nepal, Bhutan and Sikkim. It covers an area of about 4.37 million square kilometers. It has a population of more than 1 billion people.

Refers to the southern region of Asia. These include Sri Lanka, Maldives, Pakistan, India, Bangladesh, Nepal, Bhutan and Sikkim. It covers an area of about 4.37 million square kilometers. It has a population of more than 1 billion people.

The northern part of the region is the mountainous region of the southern foothills of the Himalayas, the southern part of the Indian Peninsula is the Deccan Plateau, and the northern mountains and the Deccan Plateau are separated by the Indus Gangetic Plain. Country: Pakistan, Capital: Islamabad.

Country: India, Capital: New Delhi.

Country: Maldives, Capital: Male.

Country: Sri Lanka, Capital: Colombo.

Country: Bangladesh, Capital: Dhaka.

4. Profit: It can promote the rapid improvement of the level of science and technology, promote the quality of labor, and make industrial products more competitive in the international market. Disadvantage: A world-class crisis will inevitably affect Japan's economic development, sometimes with a fatal blow.

1Pacific Ocean, Seto Inland Sea.

2 Europe is the lowest continent in the world. The ground is gently undulating, the terrain type is mainly plain, and the mountains are mainly distributed on the north and south sides.

3 South Asia is located in the Himalayas in southern Asia, a vast area between the western part and the Indian Ocean. The latitude is between 0° 40°N (north latitude) and the longitude is 60°E (east longitude) 100°E. There are 7 countries.

Nepal and Bhutan are landlocked countries, India, Pakistan and Bangladesh are coastal countries, and Sri Lanka and Maldives are island countries. The capital of Nepal is Kathmandu, the capital of Bhutan is Thimphu, the capital of India is New Delhi, the capital of Pakistan is Islamabad, the capital of Bangladesh is Dhaka, the capital of Sri Lanka is Colombo, and the capital of Maldives is Male. The Himalayas separate South Asia from the rest of Asia, making it a relatively independent unit geographically.

4. Japan's small area and lack of mineral resources make the processing economy beneficial to Japan's economy; Japan's over-reliance on the international market for industrial products is her drawback.

One. Pacific coast and Seto Inland Sea coast.

Two. 2.Characteristics: The terrain is high from north to south, low in the middle, mainly plains, it is the lowest altitude in the world on a continent, and there are many glaciers.

Numerous rivers and lakes.

1. Inner rivers: mostly distributed in the northwest inland area, the river water mainly comes from (ice and snow melt and seasonal precipitation), and most of them belong to the (seasonal break) flow river.

2. Lakes: mostly distributed in the middle and lower reaches of the Yangtze River and the Qinghai-Tibet Plateau. It is relatively concentrated in the plain of the middle and lower reaches of the Yangtze River, the lower reaches of the Huai River and the southern part of Shandong Province.

2. Governance of the Yellow River.

1: The benefits of the Yellow River: there are many canyons, rich (hydropower) can be used for power generation, and water diversion irrigation makes (Hetao Plain) become "plugged in the south of the Yangtze River".

2: Damage of the Yellow River: Grassland degradation in the upper reaches, serious (soil erosion), and flooding.

There are many tributaries that flow through (Loess Plateau), carry a large amount of sediment, and the downstream formation ("above-ground river") has been formed in Shandong

3: The management of the Yellow River: the upper and middle reaches: especially in the Loess Plateau, carry out comprehensive management (afforestation), and build large reservoirs, such as (Xiaolangdi) water conservancy projects; Downstream: Reinforcement (embankment).

Three: Yangtze River. 1. Development of shipping.

1: Conditions: The main branch of the Yangtze River accounts for 73% of the country's navigation mileage, known as the "** waterway" The main stream runs through the east and west, does not freeze all year round, and is navigable in all seasons.

2: Measures: focus on the management of the Sichuan River and the "Jiuqu ileum" (Jingjiang waterway), the Yangtze River waterway, the Pingzi flood, (strengthen the construction of the port.

3.North temperate zone.

4.Mediterranean climate Location on land and sea.

1.China's economic growth rate is faster than that of the United States and the world average, ranking first in the world.

2.The top three countries in the world in terms of both area and population are China located in Asia. But the theme of this century is peace and development

3.Warm in spring, hot in summer, cool in autumn, and cold in winter describe the change in temperature in the temperate zone.

4.The type of climate that is lacking in the southern hemisphere is the subarctic coniferous forest climate The main reason for the lack of precipitation in Urumqi, Xinjiang is that it is deep inland

1 Japan....Two.

2 China, Asia, peace and development.

3 mid-latitudes. 4. Kelp tundra climate (check the review materials for the third year of high school to the college entrance examination), deep inland.

1. c 30°N and its vicinity are controlled by the subtropical high all year round.2 and d Since this is over the North Pole, a 60° rotation from 180° clockwise is 120°e near the morning line, so it is about to sunrise The answer d is the closest.

3. d The occurrence of polar day in the Arctic Circle indicates that it is the summer of the Northern Hemisphere a - North China is a temperate monsoon climate The southeast wind prevails in summer b - The Thames River is located in the United Kingdom Typical temperate oceanic climate The annual precipitation is relatively average Slightly more in winter But.

In the summer, it does not cause a significant decrease in the water level The word "obvious" is too highc - at the beginning of July, the sun is near aphelion, and the time should be around July from this question, and it is clear that the sun does not have perihelion.

1. The dimension of A is 30 degrees N, so C (polar high pressure zone, subpolar low pressure zone, subtropical high pressure zone) is selected

2. The line that passes 180 degrees is the ray and crosses the other side of the earth, then here is the prime meridian, which is 0 degrees, and the Beijing time is 108 degrees north, which is not bad at A, analyzing this figure, the left is day, and the right is night, (the area of day is larger than the area of night), so it is about five o'clock in the morning.

D3,a North China northwest wind, which is caused by the Siberian high in winter.

b The Thames River has the greatest flow in winter.

c, January Sun is at perihelion.

d, summer is the rainy season in South Asia.

Option D (this diagram is not winter, because the Arctic is all night in winter, and there is no day) is welcome.

c d d

The three pressure zones in the shade are the polar high pressure zone, the subpolar low pressure zone, and the subtropical high pressure zone from the inside to the outside.

Judging from the morning and dusk line, the north of 70 degrees north latitude has entered the polar day, so the time should be at the end of May and the beginning of June, when South Asia enters the rainy season.

The position of the 180-degree meridian in the figure can be judged to be the position of 120 degrees east longitude, that is, the position of the local time in Beijing time, so it can be judged that Beijing is about to rise at this time, so 5 o'clock is the closest.

The highest altitude angle of the sun is 12 o'clock at noon and 11:20 in Beijing, which is almost 40 minutes, so it is 130 e east longitude. ）

It should be the local summer solstice night length equal to 9 hours, so the winter solstice day length is 9 hours) Beijing time at 6 o'clock is also 7 o'clock in the local area, so it is excluded for the winter half year ab, c is not necessarily if it is close to the vernal equinox can also be, and the revolution is slower)

4b (remember that in the second half of the year, the whole world is northeast and northwest).

According to ** data, 3:50 Beijing time is the sunrise of the observation site, 11:20 Beijing time is the noon of the observation site, and 18:50 Beijing time is the sunset of the observation site.

7. When Beijing time is 11:20 and the local area is noon, the local longitude can be calculated as 120+ (12:00-11:

20) 15 degrees = 130e, and according to the solar altitude angle of 73 degrees 26 minutes at this time (noon), the latitude of the observation site is x, i.e.

73 degrees 26 minutes = 90 - (x - 23 degrees 26 minutes), so the latitude is 40n, choose a for question 7

8. The day length of the observation site on this day (June 22) = sunset - sunrise, that is, 15 hours, so the day length of December 22 is 24-15 = 9 hours.

Therefore, choose C9, when the school rises at 6 o'clock Beijing time, it is 6:40 locally, so it should belong to the winter half of the year, and the direct sun point moves southward, so choose C

On the 1st of the month, the direct point of the sun is in the northern hemisphere, and at this time, except for the polar daytime region, the sunrise direction is northeast, and the sunset direction is northwest. Therefore, when the students of the school observe the sunrise and sunset, the sun is located in the northeast and northwest directions of the observer, respectively, so B is chosen.
