Geographical location of the United States
The United States is located in the southern part of North America, bordering the Atlantic Ocean to the east, the Pacific Ocean to the west, Canada to the north, and Mexico and the Gulf of Mexico to the south.
Terrain
The entire territory can be divided into 5 geographical regions from east to west: The southeastern coastal plain is divided into two parts: the Atlantic coastal plain and the Mexican coastal plain. The altitude of this area is below 200 meters, and most of it is formed by alluvial rivers, especially the Mississippi River Delta, which is the largest delta in the world. The soil is black and fertile. There are some marshy areas near the mouth of the river. The Florida Peninsula, located in this geographical area, is the largest peninsula in the United States. The Appalachian Mountains are located on the west side of the Atlantic Coastal Plain, basically parallel to the coast. They are about 2,300 kilometers long, generally at an altitude of 1,000 to 1,500 meters, and are composed of several parallel mountains. The interior plains are in the shape of an inverted triangle, stretching from the long border between the United States and Canada in the north to the Rio Grande River in the Atlantic Coastal Plain in the south. The Western Mountain System consists of two mountain ranges in the west, the Rocky Mountains in the east and the Sierra Nevada and Cascade Mountains in the west. The product of the old fold movement. Mount Whitney in the Sierra Nevada, with an altitude of 4,418 meters, is the highest point in the continental United States. Mount Rainier in the Cascade Range, with an altitude of 4,392 meters, is second only to Mount Whitney. The Western Intermountain Plateau consists of the Colorado Plateau, Wyoming Plateau, Columbia Plateau and the Grand Canyon. It is the most complex geological structure in the western United States. The Grand Canyon is located in northwest Arizona. It is composed of a series of twists and turns, intricate gorges and deep valleys. It is majestic and has steep rock walls. It is a rare natural landscape in the world. The United States has many rivers and lakes and complex water systems, which can be generally divided into three major water systems: All rivers east of the Rocky Mountains that flow into the Atlantic Ocean are called Atlantic water systems, including the Mississippi River, Connecticut River and Hudson River. The Mississippi River is 6,020 kilometers long, ranking third in the world. Any river that flows into the Pacific Ocean is called the Pacific River System. The main ones are the Colorado River, Columbia River, Yukon River, etc. A group of great lakes in central and eastern North America. Including Lake Superior, Lake Michigan, Lake Huron, Lake Erie and Lake Ontario, with a total area of ??245,000 square kilometers. It is the largest freshwater body in the world and is known as the "North American Mediterranean". Lake Michigan belongs to the United States, and the other four lakes Available exclusively for the United States and Canada. Lake Superior is the world's largest freshwater lake, ranking second in area among world lakes after the Caspian Sea.
Climate
The climate in most areas of the United States is temperate and subtropical, with moderate temperatures and abundant precipitation. Due to its vast territory and diverse topography, climate change is relatively complex. The southern tip of the Florida Peninsula is tropical. Alaska is located between 60 and 70 degrees north latitude and belongs to the cold climate zone within the Arctic Circle; Hawaii is located south of the Tropic of Cancer and has a tropical climate. The northeastern coast of the United States has a continental temperate broadleaf forest climate. Affected by the Labrador cold current and the cold air from the north, the winter is cold, with the average temperature in January being around -6°C, and the summer is mild and rainy, with the average temperature in July being around 16°C. The average annual precipitation is about 1000 mm. The southeastern United States and the Gulf Coast have a subtropical forest climate, which is warm and humid with luxuriant plants. Affected by the Gulf Stream, the climate is warm and humid. The average temperature in January is 96°C, the average temperature in July is 24-27°C, and the average annual precipitation is 1,500 mm. The central plains of the United States have continental climate characteristics, with cold winters, with an average temperature of about -14°C in January, and hot summers, with average temperatures in July as high as 27-32°C. The average annual precipitation is 1000-1500 mm. The plateau in the western inland region has dry and cold winters and dry and hot summers. It has an inland climate. The annual temperature difference on the plateau is large, and the annual temperature difference on the Colorado Plateau is as high as 25°C. The average annual precipitation is less than 500 mm, and the precipitation in the plateau desert areas is less than 250 mm. The northern section of the Pacific Coast is humid and rainy all year round and has a temperate maritime climate, but it is dry and rainless in summer. This area has warm winters and cool summers, with abundant rainfall. The average temperature in January is above 4℃, and in July the average temperature is around 20~22℃. The average annual precipitation is about 1500 mm.
Japan’s geographical location
Located on the west coast of the Pacific Ocean, it is an arc-shaped island country extending from northeast to southwest. It faces China, North Korea, South Korea, and Russia across the East China Sea, Yellow Sea, Korean Strait, and Sea of ??Japan to the west. The land area is 377,880 square kilometers, including the four large islands of Hokkaido, Honshu, Shikoku, and Kyushu and more than 6,800 other small islands. The territorial sea area is 310,000 square kilometers. There is a territorial dispute with Russia over the "Four Northern Islands" (Russia's name is the "Southern Kuril Islands"), and there is a territorial dispute with South Korea over Takeshima (the South Korea's name is "Dokdo"). Mountains and hills account for 71% of the total area. There are more than 160 volcanoes in the country, more than 50 of which are active volcanoes and are famous earthquake areas in the world. Mount Fuji is the highest peak in the country, with an altitude of 3,776 meters. Hot springs are located all over the country. The river flow within the territory is short, and the longest Shinano River is about 367 kilometers long. The largest lake is Lake Bipa, covering an area of ??672.8 square kilometers. Because it is surrounded by the ocean, it has a temperate maritime monsoon climate, which is mild and humid all year round, with no severe cold in winter and no scorching heat in summer. There are many typhoons in summer and autumn, and there are many plum rains in June.
The average temperature in January is -6℃ in the north and 16℃ in the south; in July, it is 17℃ in the north and 28℃ in the south. The annual precipitation ranges from 700 to 3500 mm, with the highest reaching over 4000 mm.
Resources:
Resources are scarce and more than 80% rely on imports. The main resource reserves are: 6.896 million tons of gold ore, 16.897 million tons of silver ore, 621,000 tons of iron ore, and 8.265 million tons of coal (the above figures are based on statistics from 2000). The amount of lead ore is 43.179 million tons (statistics in 1992), and the amount of copper ore is 11.553 million tons (statistics in 1996). Oil is 100% imported. Nuclear energy was developed earlier. As of August 2002, it had 53 nuclear power stations with a total installed power generation capacity of 45.907 million Kw (kilowatts). The forest area is 25.21 million hectares, accounting for 2/3 of the total land area. It is one of the countries with the highest forest coverage rate in the world. However, 52% of timber is imported, making it the country that imports the most timber in the world. Japan has many mountains and rivers and is rich in hydropower resources, with reserves of approximately 135.3 billion Kwh (kilowatt hours) per year. Japan's exclusive economic zone is about 10 times the size of its land and is rich in fishery resources. However, due to overfishing and other reasons, the amount of resources has gradually declined in recent years.
China’s geographical location
The People’s Republic of China is referred to as China. It is located in the northern hemisphere, on the east side of the world's largest continent - Eurasia - and on the west coast of the world's largest ocean - the Pacific Ocean, not far from the Indian Ocean to the southwest.
Most of China’s territory is located in mid-latitudes. The northernmost boundary is on the center line of the main channel of Heilongjiang north of Mohe, Heilongjiang Province (53°34′ north latitude), and the southernmost boundary is at Zeng of the Nansha Islands in Guangdong Province. Near the mother shoal (3°51′ north latitude), it extends 5,500 kilometers from north to south and spans about 50 degrees of latitude.
Due to different latitudes, the angle of incidence of the sun and the length of day and night vary greatly between the north and the south. This results in differences in radiant energy and temperature. From south to north, the country (except for the alpine areas of the Tibetan Plateau) spans six temperature zones: the equatorial zone, the tropics, the subtropics, the warm (southern) temperate zone, the middle temperate zone and the cold (northern) temperate zone. Among them, the subtropical zone, warm temperate zone and mid-temperate zone account for 70% of the country's area. And because it is located in the eastern part of the continent, the monsoon climate is significant. Most areas are affected by the summer monsoons from the Pacific and Indian Oceans. Rain and heat occur in the same season in the summer half of the year. The temperature and moisture conditions are well coordinated, providing superior conditions for the development of agriculture. In particular, the subtropical region, which accounts for 26% of the country's area, has high temperatures and abundant rainfall. The natural vegetation is subtropical monsoon forest and evergreen broad-leaved forest, which is suitable for growing rice and a variety of subtropical cash crops. This area is in the return high pressure zone with the same latitude as the western part of the mainland. Desert landscapes with little controlled precipitation are very different. Inland northwest China and the Qinghai-Tibet Plateau, which are far away from the sea and difficult to reach by the summer monsoon, are arid areas.
The easternmost boundary of China is at the confluence of the main channels of the Heilongjiang and Ussuri Rivers in Heilongjiang Province (135°05′ east longitude), and the westernmost boundary is on the Pamir Plateau in the Xinjiang Uygur Autonomous Region (near 73° east longitude) ). The distance from east to west is 5,200 kilometers, spanning nearly 62° of longitude. The time difference is more than 4 hours. In the world standard time zone, China’s territory is divided into five time zones from East 5th to East 9th. At present, except for the Xinjiang Uygur Autonomous Region, China uses the time in the East Eighth District where Beijing is located as the national standard time, and calls it "Beijing time".
China has a vast territory, with a total land area of ??approximately 9.6 million square kilometers, accounting for approximately 1/15 of the world’s land area and 1/4 of Asia’s area. Among countries in the world, China ranks third in area after Russia and Canada.
China’s land border is more than 20,000 kilometers long. Neighboring countries bordering China: North Korea in the northeast, Russia and Mongolia in the north, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, India, Nepal, Sikkim and Bhutan in the west and southwest, Myanmar, Laos and Bhutan in the south. Vietnam.
Eastern China faces the ocean, with a total coastline length of more than 32,000 kilometers. Among them, the mainland coastline is more than 18,000 kilometers long, starting from the mouth of the Yalu River in the north to the mouth of the Beilun River in the south. The seas surrounding the edge of mainland China include the Bohai Sea, Yellow Sea, East China Sea and South China Sea from north to south. They are connected with the Pacific Ocean (see China's offshore waters). China is one of the countries with the most islands in the world. Nearly 86% of them are distributed in the mainland offshore and South China Sea south of Hangzhou Bay. The eastern coast of Taiwan Island and the coasts of islands such as Diaoyu Island and Chiwei Island are directly adjacent to the Pacific Ocean (see China's Islands).
Countries facing China across the sea include South Korea and Japan in the east, and the Philippines, Malaysia, Brunei and Indonesia in the southeast
