Those who understand geography are geographical...

It is correct that the beginning of July is at aphelion, and the beginning of January is at perihelion.

1. You say that aphelion is summer, which is relative to the northern hemisphere; If in the Southern Hemisphere, the Earth orbits at aphelion, then it is winter in the Southern Hemisphere. Don't forget that the Earth's axis and the ecliptic plane are angled, and the seasons in the northern and southern hemispheres are reversed.

2. The length of the distance from the sun does not determine the season, but the length of the season. According to Kepler's theorem, it can be seen that the earth orbits faster at perihelion and slower when it orbits to aphelion, so the summer in the northern hemisphere is longer than the winter, and the winter in the southern hemisphere is longer than the summer.

First of all, it's important to note that the Earth is inclined, not vertical, and if it's vertical, then that's true.

The farther away the same area, the cooler the temperature.

When there is an inclination, there is a change in the angle of direct sunlight (since we know that perihelion, aphelion, is one higher geography.

The characteristics of the bisected figure should be known) In winter, the sun shines directly on the Southern Hemisphere For people in the Northern Hemisphere.

It's winter, and people in the Northern Hemisphere are far away from the point of direct fire, and the natural temperature feels low.

Ahelion and perihelion only affect the speed of the Earth's revolution around the Sun, and the closer it is to the Sun, the greater the gravitational pull.

Gravitation) So the faster the revolution has nothing to do with temperature.

The earth rotates at the same time, and the attitude is tilted, so there is an angle between the earth's rotation plane and the orbital plane, and when the earth turns to the perihelion, that is, around December 22, because of the tilt of the earth, the sun directly hits the Tropic of Capricorn; When the earth turns to the aphelion, that is, around June 22, when the sun hits the Tropic of Cancer directly, it will be hot, As for the relationship between distance from the sun and temperature, the distance at that point in the huge universe is nothing, such as the plain and the plateau, according to your understanding, it is not that the plain will be cold, the plateau will be hot, hehe, the perihelion and aphelion point determine the rotation speed of the earth, and it should be faster at perihelion.

The temperature mainly comes from the ground rather than the sun. Because the atmosphere does not absorb solar short waves very much. and absorbs ground long waves.

In winter and summer, if there is no atmosphere, the temperature of the ground is almost indistinguishable from that of the moon and other planets without an atmosphere, only day and night. In other words, the ground temperature is not mainly affected by distance. It is affected by the height of the sun.

But in summer the sun is high, the light is concentrated, and the ground temperature is high. The ground also reflects more heat into the atmosphere. The temperature is high. Winter is the opposite.

This is because July is aphelion, but the sun shines directly in the northern hemisphere, and January is aphelion, and the sun shines directly in the southern hemisphere.

I've lived in the Northern Hemisphere, so the aphelion is summer. Perihelion is winter.

If you look at the countries of the southern hemisphere, it's the opposite, like Brazil, Australia

The near and far places do not have much effect on the Earth's temperature, what matters is the angle of the sun. The axis of rotation of the earth is inclined and the pointing is basically unchanged, our country is located in the northern hemisphere, when the orbit position is apogee (early July), the direct point of the sun is in the northern hemisphere, so it is summer, and when it reaches the perigee, the direct point is in the southern hemisphere, so it is winter at this time.

The earth revolves around the sun, yes. In the Northern Hemisphere, January at perihelion is winter, and July at aphelion is summer. Then in the Southern Hemisphere it's the opposite. Therefore, the question of the division of seasons is not a question of distance and proximity.

Confusing two issues: the relationship between air temperature and the distance of the Earth from the Sun.

First, air temperature has little to do with solar radiation, but with ground radiation. The atmosphere absorbs very little solar radiation energy directly, and its temperature comes mainly from ground radiation.

Second, aphelion and perihelion indicate how close the Sun is to the Earth, and there is no direct relationship with the temperature.

In January, the Earth is closest to the Sun, which is called perihelion (summer in the Southern Hemisphere and winter in the Northern Hemisphere).

In July, the Earth is furthest from the Sun, and this position is called aphelion (summer in the Northern Hemisphere and winter in the Southern Hemisphere).

b Fly north along the meridian coil, that is, towards the North Pole, and therefore north.

After flying to the North Pole, because the North Pole is the northernmost place, no matter where you fly over the North Pole, you will go south.

After flying south to the South Pole, the South Pole is the southernmost place, so no matter where you fly over the South Pole, you will be heading north.

To sum up, the direction is north-south-north.

b.The meridians represent the north-south direction. Flying along the meridian to the North Pole is due north, passing through the North Pole and reaching the South Pole is flying all the way to the south, and then flying north again after passing the South Pole.

Due North, Due South, Due North.

It's easy.

1.The distribution of crustal thickness in the area shown in the figure is thick in the west and thin in the east, and the thickness of the crust becomes thinner with the east. It is speculated that the contours of crustal thickness are related to altitude and land and sea location.

2.Since the depth of the epicenter is 14km, and the thickness of the crust in this area is about 40 45km and 14 40km from the local latitude and longitude position of Xingwen, Yibin, the thickness of the crust in this area is about 40 45 km and 14 40 km, so the ** in this area occurs in the crust.

3.**The waves generated are divided into transverse, longitudinal, and surface waves, with the first two occurring at the hypocenter. The propagation speed of longitudinal waves is faster, generally 5 6km s, which causes the building to shake up and down, and the damage search and pin force is small; The speed of the transverse wave is slower, generally 3 4 km s, causing the building to shake from side to side, and the destructive force is very large.

The vast majority of the world's ground bucket resistance is a shallow source (hypocenter depth 0 70km). Based on the thickness of the deepest crust, the longitudinal wave velocity is 6 km s and the transverse wave velocity is 3 km s, and the interval between the two waves is about 12 s.

4.Earthquake avoidance measures that schools can take: seismic reinforcement of buildings when there is no **; **When the incident occurred, the teachers and students on the ground floor evacuated to the playground, and the teachers and students at the top level hid under the tables and chairs nearby.

This is the Leizhou Peninsula, and the judgment is based on the fact that the island that is crossed by 20 degrees north latitude in China is Hainan Island, and to the north is the southernmost point of Guangdong and the southernmost Leizhou Peninsula in Chinese mainland.

Geography is a general term for the natural environment (mountains, rivers, climate, etc.) and social factors of the world or a certain region. The word "geography" was first used in the Chinese Book of Changes. Ancient geography mainly explored methods of measuring the shape and size of the earth, or describing known regions and countries.

Geography is the study of various natural and human phenomena in the geographical environment of the earth's surface, as well as the interrelationships between them. Geography is a comprehensive basic subject.

Geography is mainly a discipline that studies various natural and human phenomena on the earth's surface, as well as the interrelationship between them.

Geographically, there are six winds and seven belts.

Geography is a discipline about the relationship between a person living on earth and the geographical environment in which he lives. Generally speaking, geography covers the various environments of human life, that is, the natural environment and the human environment. The natural environment includes the atmosphere, hydrosphere, lithosphere, biosphere, pedosphere and other spheres, which gives rise to various branches of geography, such as climatic phenomena, hydrological phenomena and water environment, natural resources on the earth, landforms, the distribution of organisms and ecological phenomena, the distribution and types of soil, and many other phenomena, in addition to these, physical geographical phenomena also focus on the surface system phenomena due to the interaction of style, hydrology, plants, and soil, as well as various environmental phenomena and climatic phenomena due to human activities.

Therefore, scholars call such a discipline physical geography. In addition to physical geography, human beings are social, so they also include the relationship between various human social phenomena and the geographical environment, such as the distribution of agriculture, the distribution of industry, the distribution of settlements, etc., especially focusing on the relationship between human economic activities and the environment, but the content of this aspect is relatively broad, involving a lot of scope and it is not easy to distinguish from others, let's call it human geography (including economic geography). One of the most prominent concepts of human geography is to achieve the harmony and unity of human beings and the environment, that is, sustainable development.

Geography is a general term for the natural environment (mountains, rivers, climate, etc.) and social factors of the world or a certain region.

It is a discipline that studies the structure of the earth, etc.

In fact, the purple sand mine in Changxing is no worse than Yixing, Yixing City, located at the southern end of Jiangsu Province, belongs to Wuxi City. Changxing County, located at the northern tip of Zhejiang Province, belongs to Huzhou City, and faces Wuxi across the lake. Changxing borders the Yixing region, and its purple clay pot production uses the same purple sand mud vein.

Historically, Changxing and Yixing have had the saying of "South Kiln and North Pottery", "South Kiln" refers to Changxing, and "North Pottery" refers to Yixing. Taste tea and taste life).

Yixing's purple sand has formed an industry. In Shuangqiao Village, Yinjia Village and other villages in Dingshu Town, there are many purple sand workshops, almost reaching the level of "every family pounds mud and every household makes pottery". In 2005, Yixing's purple sand has been successfully declared as a national intangible cultural heritage and listed as the first in the handicraft technology category.

However, in recent years, the purple sand industry, which can represent Changxing, has gradually shrunk. Because the Changxing purple sand industry is shrinking under multiple pressures such as market and talents, it is facing the embarrassing situation of no successor.
