The Amazon Jungle is the world’s largest tropical rainforest. It is nearly 6 million square kilometers in size and houses the widest variety of plant and animal life than any other place on the planet. It also is home to the second largest river on Earth, the Amazon River. The jungle is mostly in Brazil, but it also spreads to eight neighboring countries in South America; Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname, and French Guyana. (Webmaster, “Amazon Jungle facts and history in brief”) There are believed to be around 6,000 different species of trees just in the Brazilian region of the Amazon. (Browder 247) Because of the mass amounts of plant…
Station 1: Our Australopithecene ancestors When comparing the two species Kenyanthrpus platyops and Australopithecus afarensis, there are many differences, some known and unknown. Looking at the canines of both species, we can see that Australopithecus afarensis didn’t have either prominent canines or a diastema and in Kenyanthrpus platyops we are not sure whether it did or not due to the lack of evidence in the fossil remains. As for the molars, Australopithecus afarensis had more parallel molars to apes than humans while in Kenyanthrpus platyops it is hard to tell whether it is parallel or parabolic: nevertheless, they look to be more parabolic shape. The cheek bones on Australopithecus afarensi are somewhat prominent compared to head size and there is no fossilization of the cheek bones in Kenyanthrpus platyops to determine the shape of them.…
The Amazon basin in South America, vegetated by tropical rainforest, lies within the equatorial climate zone and covers an area of some 8,235,430 km 2 mainly in Brazil. The Amazon River flows through the basin from its source high in the Andes towards its mouth in the Atlantic Ocean, and is the largest single source of freshwater runoff on Earth, representing 15-20% of global river discharge. At present the amazon rainforest acts as a carbon sink. It absorbs around 35% of the world’s annual carbon dioxide emissions and produces more than 20% of the world’s oxygen. It contains the greatest biodiversity on Earth, providing a habitat for more than half the worlds estimated 10 million species of plants animals and insects.…
The equatorial climate has little variation resulting in a hot wet climate all year round, the Amazon rainforest in Brazil has a mean monthly temperature of around 28°C, ranging between 25°C and 27°C. The Amazon rainfall averages 2677mm per annum. Most precipitation occurs during the day giving the Amazon its hot and wet climate. Primary productivity in the Amazon rainforest is very high, and is the most biologically diverse region in the world, it has nearly 200 species of mammals, more then 500 species of bird, more than 300 species of fish and 180 tree species. Competition being exceeding high ensures that very few species dominate. The rainforest has developed over a long period of time, which has encouraged complex food webs do develop. The constant warm temperatures allow for reproduction throughout the year, this allows for natural selection and evolution to take place at a rapid rate, showing how the Amazon rainforest is a natural response to the climate.…
The government of Brazil and America are both similar and different at the same time. Brazil was run as a monarchy up until 1988 when it developed into a federal republic and then created separate state powers. Brazil gained its independence in 1822 from Portugal. The government set up includes an executive, judicial, and legislative branch. The country is run by president, Michel Temer. America and Brazil have differences and similarities in their government that make them both unique.…
A tropical rainforest is an ecosystem that occurs roughly within 28 degrees north or south of the equator (equatorial zone between the Tropic of Cancer and Tropic of Capricorn). They are characterised by their humidity (average of 88% in the rainy season and 77% in the dry season), hot temperature (average 27.9 °C during the dry season and 25.8 °C during the rainy season) but more importantly their extremely high rainfall (torrential rainfall - between 1,500 mm and 3,000 mm annually). Tropical rainforests contain the most diverse range and highest volume of plant and animal life found anywhere on the Earth, however, they are amongst the most threatened ecosystem globally due to the large scale fragmentation due to human activity and expansion – 16% of the Earth’s surface was once covered by tropical rainforest, yet the figure has significantly dropped to approximately 6% with no optimism of it increasing again. In this essay I will focus on the Amazon Rainforest, it is 2 times the size of India harbouring 10% of the world’s known species and is home to 350 ethnic groups.…
Many species of animals live in the Amazon Rain Forest. The rain forest itself, covering nearly 40 percent of South America, contains one in every ten species known on earth (“World’s” 1). Around 500 species of mammals, 475 reptiles, and one third of the world’s birds live in the Amazon. Although they all live in the same general area, animals have different habitats, diets, and life spans. A few of the many animals are the Scarlet macaw, Anaconda, Giant Amazon River Turtle, and the Howler Monkey.…
The Amazon is a tropical rainforest. Each year the Amazon Rainforest gets about 9 feet of rain. During the months of maximum precipitation, broad areas traversed by the Amazon are subject to severe floods. The Amazon contains more species of fauna and flora than any other ecosystem in the world. Also, the Amazon basin covers more than 2.5 million square miles more than any other rainforest.…
The Amazon is the largest tropical rainforest on Earth. It covers over 1.4 billion acres of land. About two and half million different insects and 40000 plant species live in the Amazon. Location • South of the equator • 3.1600° S and 60.0300° W • Stretches across 9 different countries in South America The abiotic factors in the Amazon Rainforest are important because they affect the plants and animals that live there. Without these factors trees and plants would not be able to grow and ultimately die.…
Human beings have exploited the tropical rainforests for many years now for their abundance of resources and their biodiversity. The moist exploited is the Amazon rainforest which has already lost 20% of its area forever. Deforestation is the single biggest threat to the rainforest; the prime cause of it is cattle ranching. This is when land is cleared to provide space for cattle ranchers to herd their livestock to help increase beef production. This activity accounts for 60% of deforestation in Brazil, which is having a major effect on the biodiversity of the ecosystem. The impacts of deforestation are wide. In the Amazon there have been problems with increased forest fires, soil erosion and decreased biodiversity, caused by habitat loss. Subsistence farming is another factor…

Brazil is home to nearly 60% of the Amazon Rainforest. The Brazilian government recognizes only 13% of the total land mass of Brazil as being designated to its native tribes. Of this 13% total land mass, 98.5% lies in the Amazon Rainforest (http://survivalinternational.org/tribes/brazilian). In Chapter 5 of Mann’s 1491, Mann retells the story of the Gonzalo Pizarro exhibition. The first recorded and written description of the Amazon comes from Gaspar de Carvajal, the chaplain on the Pizarro voyage.…
The Amazonian Rainforest consists of an expansive 350 million square acres smack in the middle of Brazil and many other countries. It is the largest rainforest in the world and is home to hundreds of indigenous species of plants and animals. However Brazil’s developing status is endangering the rainforests existence. It is currently reported that 500,000 trees are cut down every hour, and the country is losing anywhere from 20,000 to 100,000 species a year. To many this is unacceptable and the amazon should be protected, others believe that operations should continue as is. In reality the Amazon Rainforest needs to be developed in a sustainable manner because the rainforest is home to many species and is detrimental to global health, Brazil…
The Amazon is the longest river in the South America. It originates in the Peruvian Andes, and flows approximately 6, 450km (4, 000 miles) to its mouth in the Atlantic Ocean. It is the world’s second longest river. No other river approaches its volume of flow, which exceeds that of the world’s 10 next largest rivers, combined.…
