Question

Describe about amazon rainforest

Answer 1

Answer:

Explanation:

he Amazon Jungle, as it is commonly known in English, is a magnificent broad-leafed rainforest in the heart of Brazil, the basin of which covers an impressive area of 7 million square kilometres (or 1.7 billion acres).

It has an astonishing value in the natural world in terms of the Oxygen that it provides, the Carbon Dioxide that it consumes and the splendid array of exquisite plant- and animal species to which it is home. In fact, it is home to the most diverse and numerous arrays of species in the world.

However, the Amazon is not yet a very popular or frequented tourist destination.

Answer 2

The Amazon rainforest,[a] also known in English as Amazonia or the Amazon Jungle, is a moist broadleaftropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km2 (2,700,000 sq mi), of which 5,500,000 km2(2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations.The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Surinameand French Guiana. Four nations have "Amazonas" as the name of one of their first-level administrative regions and France uses the name "Guiana Amazonian Park" for its rainforest protected area. The Amazon represents over half of the planet's remaining rainforests,[1] and comprises the largest and most biodiverse tract of tropical rainforestin the world, with an estimated 390 billion individual trees divided into 16,000 species.[2]

The rainforest likely formed during the Eocene era (from 56 million years to 33.9 million years ago). It appeared following a global reduction of tropical temperatures when the Atlantic Ocean had widened sufficiently to provide a warm, moist climate to the Amazon basin. The rainforest has been in existence for at least 55 million years, and most of the region remained free of savanna-type biomes at least until the current ice age when the climate was drier and savanna more widespread.[4][5]

Following the Cretaceous–Paleogene extinction event, the extinction of the dinosaurs and the wetter climate may have allowed the tropical rainforest to spread out across the continent. From 66–34 Mya, the rainforest extended as far south as 45°. Climate fluctuations during the last 34 million years have allowed savanna regions to expand into the tropics. During the Oligocene, for example, the rainforest spanned a relatively narrow band. It expanded again during the Middle Miocene, then retracted to a mostly inland formation at the last glacial maximum.[6] However, the rainforest still managed to thrive during these glacial periods, allowing for the survival and evolution of a broad diversity of species.[7]
