How big is the area of the Amazon?

The lower reaches of the Amazon River in South America are the largest plains in the world, with an area of 5.6 million square kilometers.

The world's largest alluvial plain, located in the middle and lower reaches of the Amazon River in northern South America. It is located between the Brazilian Plateau and the Guyana Plateau, reaching the foothills of the Andes Mountains in the west and the Atlantic Ocean in the east, and straddles the territory of Brazil, Peru, Colombia and Bolivia, covering an area of 5.6 million square kilometers (of which more than 2.2 million square kilometers are in Brazil, accounting for about 1 3 of the country's territory). The plain is wide in the west and narrow in the east, and the terrain is low and flat.

At its widest point, it is 1,280 kilometers, mostly below 150 meters above sea level, only 44 meters above sea level near Manaus in the central part of the plain, and even lower in the east, gradually approaching sea level. The plain is formed by the alluvial alluvium of the main trunk and tributaries of the Amazon River on the basis of the Amazon depression in South America, after the rise and formation of land in the Quaternary period.

The Amazon rainforest area covers 50 percent of the total area of tropical rainforests on Earth, amounting to 6.5 million square kilometers, of which 4.8 million square kilometers are in Brazil. The Chinese word Amazon (also translated as Amazon) can be divided into three different concepts: the first is the well-known Amazon River, the largest river in the world, with a total length of 6,400 kilometers, originating in Peru, crossing Brazil, and flowing into the Atlantic Ocean; The second is the Amazon Plain, which is a forested plain irrigated by the Amazon River and its tributaries, covering an area of about 6 million square kilometers, stretching from the Guiana Plateau in the north to Matogrosso in Brazil in the south, bordering the Atlantic Ocean in the east and Bolivia, Peru, Colombia and Venezuela in the west.

The third is the Amazon forest, which extends beyond the Amazon plain and refers to the South American rainforest ecosystem that is consistent with the forest type of the Amazon plain.

The Amazon plain in South America.

Amazon, alluvial plain of South America.

It is wide in the west and narrow in the east, with a maximum width of 1,280 kilometers; The terrain is low and flat. The basin is a combination of plain terrain. Also known as the Amazon Basin or Amazon Basin, it is the Amazon River in South America.

and the entire area through which its tributaries flow.

The Amazon Plain is wide in the west and narrow in the east, with a maximum width of 1,280 kilometers; The terrain is low and flat. Most of it is below 150 meters above sea level, and Manaus, in the middle of the plain, is only 44 meters above sea level, and even lower in the east, gradually approaching sea level.

The floodplain of the Amazon plain accounts for about 10% of the plain area, composed of soft modern alluvium, the terrain is particularly low, beyond the floodplain, 45 60 meters above the steep bank is the high plain, Hu Xian is blind in the west of 60 ° west longitude is the widest, the surface material is composed of sand and clay of the Tertiary and Quaternary, has been in a state of partial consolidation.

Hydrology of the Amazon Plains:

Amazon River. It is the river with the largest flow and the widest basin area in the world. Rivers are meandering, lakes and marshes are dense, and flooding is common during the flood season, with poor drainage. The mouth of the river is 240 kilometers wide and flows 180,000 cubic meters per second during flooding periods.

10 times. The amount of water in the river is so large that it degrades the sea water within 160 kilometers from the shore.

There are more than 1,000 known tributaries, seven of which are more than 1,600 kilometers long. 65,000 square kilometers of fertile silt deposited by the Amazon River have been nourished.

Its basin covers an area of about 7.05 million square kilometers, almost twice the size of any other major river basin in the world.

The Amazon Plain is located in the northern part of South America。The plain lies between the Guiana Plateau and the Brazilian Plateau, stretching from the Andean foothills to the west to the Atlantic coast to the east. With an area of 5.6 million square kilometers, it is the largest alluvial plain in the world.

Brazil covers an area of more than 2 million square kilometers, accounting for about 1 3 of the country. The Amazon River runs through the middle of the plain. The plains are low and flat, and the altitude is mostly less than 150 meters.

It is wide in the west and narrow in the east, in the shape of a funnel.

Natural resourcesThe Amazon Plain is located near the equator, backed by the Andes Mountains, and open to the Atlantic Ocean in the east, which is conducive to the convergence of hot and humid air currents from the sea inland, coupled with strong convection, high temperature and rain all year round, becoming the world's largest tropical rainforest climate zone, with a wide variety of flora and fauna. Among them, endemic plant species accounted for 1 3. It is estimated that about 800 million cubic metres of timber are stored in the forest sea, accounting for about 1.5 of the world's total timber stock.

The trees are dominated by myrtaceae, rutaceae, neemaceae, lauraceae, oleanderaceae and other tree species.

Rich in mahogany, ebony, green wood, Brazil fruit, clover gum, rolling repentance shea, Brazilian cherry fruit, ivory coconut and other economic forest trees, Brazilian cherry fruit trees can grow to 80 meters high, the oil content of cherry fruit is 73%, much higher than the oil content of sesame and peanuts, can be edible, and the economic value is particularly high.

The Amazon Plain is the world's largest mausoleum plain, located in the middle and lower reaches of the Amazon River in northern South America, between the western plateau of Ba and the Piana plateau of Guichi.

The Amazon plain in South America.

The Amazon Plain is a plain in the lower reaches of the Amazon River in South America, covering an area of 5.6 million square kilometers, making it the largest plain in the world. The Amazon Plain is low and flat, most of which are about 150 meters above sea level, and there are quite a few lowlands with lower altitudes, so it is called the "Amazon Lowland". The Amazon Plain is the alluvial plain of the Amazon River.

Once upon a time, it was a large depression submerged in the sea. The rivers of the Amazon River system, which originate in the Andes, bring large amounts of sediment and other materials from the Guiana Plateau and the Brazilian Altiplano, and over time, the depression is filled in, and a vast large plain has emerged.

The Amazon plain is lush with a wide variety of plants, with endemic species accounting for 1 3. It is estimated that about 800 million cubic metres of timber are stored in forests, accounting for about 1.5 of the world's total timber stock.

Tree species such as Myrtaceae, Rutaceae, Neemaceae, Lauraceae, and Oleanderaceae are dominant. Rich in mahogany, ebony, green wood, Brazil fruit, clover gum, shea, Brazilian cherry fruit, ivory coconut and other economic forest trees, Brazilian cherry fruit trees can grow up to 80 meters high, the oil content of cherry fruit is 73%, much higher than the oil content of sesame and peanuts, can be edible, and the economic value is particularly high.

The wildlife of the Amazon is very diverse and abundant. The rainforest is home to monkeys, tree sloths, hummingbirds, macaws, giant butterflies and countless bats, the Amazon River is home to caimans and freshwater turtles, aquatic mammals such as manatees and freshwater dolphins, and jaguars, slender-waisted cats, tapirs, capybaras and armadillos on land. There are also 2,500 species of fish, as well as more than 1,600 species of birds.

The Amazonian is the largest snake in the world, reaching a maximum of two meters and weighing more than 225 kilograms, as thick as the torso of an adult man. However, the length of the forest snake is generally about 3 meters. They are water-loving and usually inhabit muddy banks or shallow water, and prey on waterfowl, turtles, capybaras, tapirs, etc., and sometimes caimans.

The Amazon plain in South America. The Amazon Plain, located in the north of South America, in the middle and lower reaches of the Amazon River, between the Guiana Plateau and the Brazilian Plateau, west of the Andes, staring at the east of the Atlantic Ocean, across the territory of Brazil, Peru, Colombia and Bolivia, covering an area of 5.6 million square kilometers.

The Amazon Plain is wide in the west and narrow in the east, with a maximum width of 1,280 kilometers, and the terrain is low and flat. Most of them are below 150 meters above sea level, and Manaus, in the middle of the plain, is only 44 meters above sea level.

The Amazon plain is lush with a wide variety of plants, with endemic species accounting for 1 3. According to Kai's estimates, about 800 million cubic meters of timber are stored in the forest, accounting for about 1.5 of the world's total timber stock.

The Amazon Plain has a tropical rainforest climate and is the world's most extensive equatorial rainy region. It is controlled by the equatorial low pressure zone all year round, with prevailing updrafts and mostly convective rain.
