Immigrate to the dangerous Mara border

The name of North America is called North America for short.

Second, take care of yourself.

Coastline: The land coastline is about 60,000 kilometers. Compared with North Asia and America, the northern part of the west and the eastern coast of the north.

Tortuous island fjords; The southern half of the coast is relatively flat.

Peninsula and Islands: The total area of the peninsula is about 265,438 438+ 10/0,000 square kilometers, and the total area of the islands is about 4 million square kilometers, ranking first among all continents in Greenland.

Shape: The plains at an altitude of 200 meters account for about 20%, the plains and hills at an altitude of 200-500 meters account for about 22%, and the primitive mountains at an altitude of 500 meters account for about 58%. The basic feature of the whole continent is that the north-south mountains are distributed on the east and west sides and parallel to the coast, and the plains in the east of the three regions are distributed on the eastern mountain plateau with obvious shapes: the Appalachian mountains in the south of Labra Plateau on the St. Lawrence River are high in the south and low in the north, and the western side of the Appalachian mountains is 30 to the east, and gradually descends to the border of the plains: it is located between Labra Plateau, Appalachian Mountains and Rocky Mountains, starting from Hassan Bay in the north and reaching the Gulf of Mexico in the south, running through the northern half of the mainland plain. Mountain Plateau in the west of westworld: It belongs to the northern section of Cordillera Mountains and extends straight in Alaska. Southern Mexico mainly includes three parallel Shandong belts with an altitude of 2000-3000 meters. The Rocky Mountains, stretching for 5,000 kilometers from north to south, are an important climate dividing line in North America. The western belt starts from the mountains along the American coast in the south and flows into the sea in the north. The coastal islands in western Canada are 1, 000-500m above sea level. This belt includes alaska range in the north, Canadian coastal mountains, Cascade Ridge in the Sierra Nevada of the United States, etc. Mount McKinley in Alaska is 61.94m above sea level, and the bottom of the plateau basin in the eastern belt of North America is1.300-800m. The dead valley in the south of the basin is 86m below sea level, and the continental low point in the western hemisphere is 86m below sea level.

Volcanoes and Earthquakes: There are 90 North American volcanoes, 28 Aleutian Islands, 20 Alaska and 40 earthquakes in westworld, North America.

Water system: the outflow area of North America accounts for about 88% of the whole continent, belonging to the western basin, and 48% goes to the Pacific basin, each accounting for about 20%. Except the St. Lawrence River, all rivers originate in the Rocky Mountains, the East River flows into the Western Arctic Ocean, and the West River flows into the Pacific Ocean (including the current zone), accounting for about 65,438+02% of the whole continent, mainly including the Xibumei Basin and the Mississippi River in Greenland. The North American River is the fourth largest river in the world, including mackenzie river and yukon river. The waterfalls of North American rivers such as the St. Lawrence River and Rio Grande Falls are 700 meters high in the yosemite falls of Yosemite Park in the western United States. Niagara Falls is 565,438+0 meters wide. The total area of freshwater lakes in North America is about 400,000 square kilometers, ranking first in all continents. The five lakes in the plateau area in the northern half of the mainland are: Lake Superior, Lake Huron, Lake Michigan, Lake Erie and Lake Luoan, with a total area of 245,273 square meters.

Climate: The intertropical, temperate and frigid climate in North America is very complicated. The northern Arctic Circle is dominated by temperate continental climate and sub-frigid coniferous forest climate. The ice and snow world in the southern Caribbean benefits from the equatorial warm current and the average precipitation in North America.

Tropical hurricanes hit a large area of land in the north temperate zone. Because all the mountains are north-south or close to north-south, the humid air in the Pacific Ocean only reaches the western coastal areas. The cold air of the Arctic Ocean pushes southward across the plain; The humid air from the tropical western ocean passes through the plains and goes deep into the north, so the climate in North America is stable and it is cold and thawed in winter. In winter, the severe cold and snowfall occurred in the subtropical area along the Gulf Coast in Leng Yue, North America (65438+ 10), and the average temperature was below 0℃, accounting for about 3/4 of the whole continent. The whole Arctic Islands (collectively referred to as islands in northern North America and western Greenland) and Greenland are below -32℃, and Greenland is as low as -50℃. In the cold polar regions of the western hemisphere, the average temperature in the hot summer months (July and coastal August) in the northern hemisphere is 0~3℃. The rest of the vast areas are between 0℃ and 32℃, and the area of 20℃ accounts for about half of the whole continent. The area of 30℃ is larger than the Death Valley in the southwestern United States. The extreme high temperature reaches 56.7℃. The precipitation in eastern North America is about 500~300 mm higher than that in southeastern Greenland, eastern United States and Alaska Pacific coast. Canada's North American precipitation area can reach 2000 mm along Alaska's Pacific coast; The precipitation in Florida Peninsula, eastern foothills of Rocky Mountains, plains and Yukon Plateau is 250~ 100 mm; The Caribbean belongs to the tropical rainforest climate, where there is little final high temperature, rain and precipitation. The average precipitation in the southwestern part of the American basin, the Colorado River tourist area and the northern part of Greenland in the Arctic Islands is 65,438+000 mm. Every May, the southeastern part of North America is hit by a hurricane, which often causes serious disasters. In winter, there will be cold and strong storms in northern North America, and the west wind will burn wind in the foothills of eastern Chinnock through the Rocky Mountains.

Self-owned resources: The main proven minerals in North America are oil, natural gas, coal, iron, copper, nickel, uranium, lead and zinc, accounting for about 30% of the whole continental area and 65,438+08% of the total forest area in the world. The main Bush Hill is rich in Douglas fir, giant cypress, nut cobber, sugar maple, pine and redwood. Hemlock and other forest grasslands account for 14.5% of the whole mainland area and about 1 1% of the world grassland area. The hydropower resources in North America are about 248 million kilowatts, accounting for 8.9% of the world's water resources, and the developed water resources are 53.6 million kilowatts, accounting for 34.7% of the world. The coastal fishing grounds in North America account for about 20% of the total coastal fishing grounds in the world. Major fishing grounds in the eastern marginal waters of Canada

Third, the economic situation.

Industry: economically developed countries such as the United States and Canada have a solid industrial base, huge production capacity and advanced technology. Agriculture, forestry, animal husbandry and fishery are extremely developed in North America. In addition to some industrial bases in Mexico, the mining industry in North America is mainly engaged in mining tin, manganese, chromium, cobalt, bauxite, diamond, saltpeter, antimony and tantalum, such as crude oil, natural gas, iron, copper, lead, zinc, nickel and sulfur.

Agriculture: Agriculture in North America is highly specialized, commercialized and mechanized. Crops in world-famous agricultural areas include corn, wheat, rice, cotton, beans, tobacco and corn and wheat. World agriculture occupies an important position. America and the West Indies mainly produce tropical crops such as sugarcane, bananas and coffee.

Transportation: The total length of the North American railway is 420,000 kilometers, and the inland waterway is about 55,000 kilometers. Roads extend in all directions, and the developed traffic areas in the northeastern United States include the southeastern United States and the western coastal areas. Southeast Canada; The main roads and railways in eastern Mexico transport the special railway lines of Cuba Sugar Factory, which are relatively developed. River transportation in Canada in summer and sledge transportation in winter are very important, and sledge transportation in northern coastal areas is also very important.

Don't think such a question is meaningless.

A lot of trouble is my own fault.
