They are located in South America and stretch 4,500 miles from north to south, along the west coast of the continent. Types of vegetation The Polylepis forest is located in the Andes Mountains. Polylepis forests occur at altitudes of up to 4,500 meters in sheltered areas. Polylepis is a group of tree species belonging to the rose family. Fifteen species of the Polylepis genus grow in South America, from northern Venezuela to northern Chile and Argentina Another form of vegetation that is found the in the alpine biome of the Andes Mountains is the Wild Potato.
Peru and Colombia Peru and Colombia are both South American countries bordering the Pacific Ocean. They are two of eleven countries bordering water in South America. Peru was the center of several Andean Civilizations; the most common among which being the Incas. Peruvian independence was declared in 1821 after being controlled by Spanish forces for many years. There are currently 29,549,517 residents of Peru.
FARMING IN THE AMAZON According to Ladatco, the Amazon is the largest and densest rainforest in the world. Its vegetation represents 1/3 of the worlds remaining forest and provides about 15% of the earth’s new oxygen. It is located in northern South America and covers 2.5 million miles. It runs through eight countries and the second largest river is in the Amazon. The rainforest contains almost 40000 different plant species.
Today the Amazonia has had 20% of its forest destroyed as a result of cattle ranches, mining, logging and agriculture. Much of this has occurred in the last 50 years. A focus on Brazil: Brazil possesses the greatest portion of the Amazonia. Since 1970, over 600,000 sq km have been destroyed. Between 2000 and 2006 alone, 150,000 sq km (an area larger than Greece) was lost.
Organizational Method: Topical Topic : Rain-forest General Purpose: To inform Specific Purpose: To inform my audience about the two major cause rain-forest being destroyed. Central Idea : The area of rain-forest on earth is getting smaller, the reasons lead to this situation are deforestation and global climate change. INTRODUCTION: I. Rainforest are forests characterized by high rainfall, with definitions based on a minimum normal annual rainfall of 1750-2000mm. A. Around 40% to 75% of all biotic species are indigenous to the rainforests.
Machu Picchu is one of many royal estates built by the Inca Emperors. It is located in Cuzco, Peru. Machu Picchu is 7,970 feet above sea level. The mountain is smack dead in the middle of a tropical forest. Burger (n.d.), “The term Machu that precedes Picchu means old and was used by locals to differentiate it from the small hill behind it called Huayna Picchu, which means young” (p. 5) Machu Picchu was home for royal blood, servants, farmers, and care givers when not many people were around in the winter.
Plate tectonics was first suggested as a theory by the geologist Alfred Wegener in 1915 when he proposed the concept of continental drift. Back in the geological past, what is now South America, Africa, Australasia and Antarctica fitted together into a supercontinent known as Gondwanaland; with North America, Europe and Asia fitting into another supercontinent known as Laurasia. (OCR AS/A2 Geology, Mugglestone et al, 2008). These were once believed to be joined to form one major central global landmass known as Pangaea (Introducing Geology, Graham Park). But now due to the global distribution of these major plates it has been proposed by Wegener and his successors that convection currents in the mantle are the cause of the movement of plates.
Rainforest Facts • Rainforests are home to more species of plants and animals than the rest of the world put together. • An astounding number of fruits (bananas, citrus), vegetables (peppers, okra), nuts (cashews, peanuts), drinks (coffee, tea, cola), oils (palm, coconut), flavourings (cocoa, vanilla, sugar, spices), and other foods (beans, grains, fish) come from rainforests. • We lose between 50 and 130 species every day – 2 to 5 species per hour are being lost forever due to tropical deforestation. • Tropical rainforests act as a global air conditioner - by storing and absorbing carbon dioxide from the air, storing the carbon, and releasing fresh, clean oxygen. • Over 2000 tropical forest plants have been identified as having anti-cancer properties.
It has many tributaries but there are two main ones: the White Nile fed by lake Victoria and the Blue Nile coming from Ethiopian mountains. These two main branches join near Khartoum, the capital of Sudan and they continue together as Nile proper until meeting the Mediterranean Sea and forming the Nile delta in northern Egypt. Around 5000 BC, one of the first great civilizations developed in the northern Nile river valley dependent on agriculture in a land called Egypt. Water; Fertile soil; and river's flow north while prevailing wind blows south made the Nile the best transportation way, were examples of the Nile gifts. Another gift is that every year the flood came bringing disaster and famine due to destroying the crops and their villages.
Deforestation of the Amazon Rainforest The Amazon rainforest is the largest tropical rainforest in the world. It’s size is unmatched by other rainforests, because it covers over forty percent of South America, and is present in nine different countries. The total area of the Amazon consists of 1.7 billion acres, with 1.4 billion acres of dense forests. It is such a vast ecosystem, providing a home to one-fifth of the worlds plants and birds, as well as one-tenth of the world’s mammals. It is easy to see why this rainforest is so marveled upon.
