First grade geography knowledge of the United States (1)

1. The United States is located in the Western Hemisphere. There are 48 continents in the continental United States, located in the north temperate zone; there are two overseas continents, one is Alaska in the cold zone Continent, one is Hawaii located in the tropics. The United States is bounded by the Atlantic Ocean to the east, the Pacific Ocean to the west, the Gulf of Mexico to the south, Canada to the north, and Mexico to the south.

2. The population of the United States exceeds 300 million. It is a country of immigrants, with white, black and yellow people. Overseas Chinese are concentrated in cities such as San Francisco, New York, and Los Angeles. The indigenous people of the United States are Indians.

3. The terrain of the United States is distributed in a longitudinal direction. The west is the Cordillera Mountain System, which is composed of multiple parallel mountain ranges. It stretches in the western part of North and South America and is the largest mountain system in the world. The central and eastern plains are vast, accounting for more than half of the country's total area, and have vast arable land, accounting for about 10% of the world's arable land. To the east are the Appalachian Mountains. The largest river in the country is the Mississippi River, which is the fourth longest river in the world. The Five Great Lakes (Lake Superior, Lake Michigan, Lake Huron, Lake Erie and Lake Ontario) are the largest group of freshwater lakes in the world and are part of the border between the United States and Canada. Lake Michigan belongs entirely to the United States. Lake Superior is the largest group of freshwater lakes in the world. Each lake is connected by waterways and flows into the Atlantic Ocean through the St. Lawrence River. The Mississippi River and the Great Lakes provide good conditions for irrigation, shipping, etc. in the United States.

5. The United States is a major agricultural country in the world. Agricultural production has achieved mechanization and specialization, with high efficiency and large output.

6. The United States is the most industrially developed country in the world. Its main industrial areas include the northeastern industrial area, the western industrial area, and the southern industrial area. The United States is the world's high-tech industrial base. Silicon Valley, located at the southeastern end of San Francisco (San Francisco), is the earliest and largest high-tech industrial center in the United States. Its famous product is silicon wafers.

7. The United States is the world’s largest economic power, as well as the world’s largest resource consumer and waste emitter. The capital of the United States is Washington, and the largest city is New York.

1. The Five Great Lakes (see North America)

2. The Mississippi River: Originates near the Great Lakes and flows into the Gulf of Mexico. It is the fourth longest and largest river in the world and has as many tributaries as the Great Lakes. The canals are connected to form a huge inland shipping system with convenient navigation; the main source of irrigation water in the central and southern parts; the tributaries are rich in hydraulic power

3. Colorado River: It originates from the Rocky Mountains and mainly relies on ice and snow melt water for supply. It flows through arid and semi-arid areas and pours into the Gulf of California, providing valuable water sources for irrigating agricultural areas

(4) Resources--rich in natural resources such as minerals, forests, and grasslands, coal, oil, natural gas, The reserves and output of copper and iron rank among the top in the world

Coal--Oil near the Appalachian Mountains--Gulf Coast Iron--Coast of the Great Lakes

3. Human Geography Overview

　(1) Population
