Europe, Africa, North America, geographical location, topographical features, others.

Europe, whose full name is "Europe", is named after the character "Europa" in Greek mythology (Greek: ε υ ρ? πη? ), Europe is located in the northwest of the old hemisphere, bordering the Arctic Ocean in the north, the Atlantic Ocean in the west, the Mediterranean Sea and the Black Sea in the south.

The mainland is east to the polar Ural Mountains (6610' east longitude and 67 46' north latitude), south to Cape Maroqi (5 36 minutes west longitude and 36 degrees north latitude), west to Cape Rocca (9 31'west longitude and 38 47' north latitude), and north to Nuo.

The terrain in Europe has many unique features. The highest point is Mount Elbrus in the Great Caucasus, with an altitude of 5,642 meters.

The average height of Europe is 340 meters, and the terrain is mainly plain. A series of mountains stand in the south, collectively known as the Alps, of which Mont Blanc is 4807 meters above sea level, belonging to France and becoming the highest peak in Western Europe.

Europe has a dense river network and abundant water. The longest river is the Volga River, with a total length of 3,690 kilometers, and the second largest river is the Danube River, with a total length of 2,850 kilometers, which is the largest river in the world.

The coastline of Europe is very tortuous, with many peninsulas, islands, bays and inland seas. Scandinavia in northern Europe is the largest peninsula in Europe.

2. Africa

Africa (Latin: Africa), the full name of Africa, is located in the western part of the Eastern Hemisphere, southern Europe, western Asia, the Indian Ocean in the east and the Atlantic Ocean in the west, spanning the north and south of the equator, covering an area of about 30.2 million square kilometers (land area), accounting for 20.4% of the total land area of the world. It is the second largest continent in the world and the second largest continent in population (about 65,438+).

The African continent reaches Cape Hafeng in the east (5124' E and 0/0 27' N), Cape Gullers in the south (20 02' E and 34 51'S) and Cape Verde in the west (0/7 W).

Among the continents in the world, Africa has the least number of islands. Most of them are small islands except Madagascar (the fourth largest island in the world). The total area of the island is about 620,000 square kilometers, accounting for less than 3% of the total area of the whole continent.

The African continent is wide in the north and narrow in the south, showing an equilateral triangle. The longest from north to south is about 8,000 kilometers, and the widest from east to west is about 7,500 kilometers. Africa is a plateau continent with relatively flat terrain, and the obvious mountains are limited to the north and south ends. The average elevation of the whole continent is 750 meters.

3. North America

North America (English: North America) is located in the northern part of the western hemisphere. It is the second developed continent in the world, among which the American economy ranks first in the world, which has an important influence on the global economy and politics.

North America has a total area of 24.228 million square kilometers (including nearby islands), accounting for about 16.2% of the world's total land area, making it the third continent in the world. It is adjacent to the Atlantic Ocean in the east, the Pacific Ocean in the west, the Arctic Ocean in the north, South America bounded by the Panama Canal, and Europe across the Danish Strait in the northeast.

The mainland reaches Cape St. Charles (55 40 ′ w, 5213 ′ n) in the east, Cape Mariato (8105 ′ w, 712 ′ n) in the south and Prince of Wales (168) in the west.

Plains below 200 meters above sea level account for 20%, plains and hills above 200-500 meters account for 22%, plateaus and mountains above 500 meters account for 58%, and the average elevation of the whole continent is 700 meters. The basic feature of continental topography is that the north-south mountains are distributed on the east and west sides parallel to the coast, and the great plains are distributed in the middle.

Race:

1, Europe

The vast majority of European residents are white, and 99% belong to European race (white), which is a continent with relatively single racial composition.

Population: 73 1 100 million (up to 20 12), the population distribution is relatively uniform, with an average density of 70 people per square kilometer.

The urban population accounts for about 64% of the population of the whole continent, ranking third among all continents after Oceania and North America.

2. Africa

Africa is the region with the most complex ethnic composition in the world. Most ethnic groups in Africa belong to black people, and the rest belong to white people and yellow people.

By 20 16, the population of Africa will be about1200 million, and the world population will be 7.35 billion (20 16), ranking second in the world after Asia. The average annual population growth rate in Africa is 2.3%, much higher than that in Asia (1%), and the population growth rate in sub-Saharan Africa is higher than that in North Africa. There are many poor people, which are expected to reach 2 billion by 2050.

3. North America

Most of the residents are descendants of European immigrants, of which Anglo-Saxons are the most; Followed by Indians, blacks and hybrids. In addition, there are Inuit, Puerto Ricans, Jews, Japanese and China people. The languages are English and Spanish, followed by French, Dutch and Hindi.

The total population is 528.72 million (2008), accounting for about 8% of the world's total population. The population distribution of the whole continent is very uneven. Most of the population is distributed in the southeast and southwest coastal areas, and the population density is the highest near new york and around Lake Erie, with more than 200 people per square kilometer.

The vast northern areas and the western inland areas of the United States are sparsely populated, and some places are even uninhabited, with less than 1 person per square kilometer.
