The Grand Canyon
The Grand Canyon is a steep-sided gorge carved by the Colorado River in the United States in the state of Arizona. It is largely contained within the Grand Canyon National Park — one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery. This picture is a view from the South Rim of the canyon.
Longstanding scientific consensus has been that the canyon was created by the Colorado River over a six million year period. The canyon is 277 miles (446 km) long, ranges in width from 4 to 18 miles (6.4 to 29 km) and attains a depth of over a mile (1.83 km) (6000 feet). Nearly two billion years of the Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. The "canyon began in the west, followed by another that formed in the east. Eventually, the two broke through and met as a single majestic rent in the earth some six million years ago. The merger apparently occurred where the river today bends to the west, in the area known as the Kaibab Arch.
GALÁPAGOS ISLANDS
Galápagos Islands are home to many different life the population is now 40,000 it has grown 40 fold. The language spoken there is always Spanish. There are 13 different Galápagos islands and only about 200 Galápagos tortise. The Galápagos islands are east to the Pacific Ocean. Out of all the 13 islands the oldest know to man is 3.5 million years old. All the islands are very steep due to the erosion but it is very good to some of the animals that live there such as the waved albatross. There are only two ways to enter and exit the islands. The names of the 13 islands are Narborough, Santa Maria, Tower, Ecuador, Bindloe, Duncan, Abingdon, Jervis, Chatham, Indefatigable, Barrington, San Salvador and Wenman. The Europeans discovered the islands on March 10, 1535 the islands first appeared on a map drown by two men named Abraham Ortelius and Mercator. They first named the islands the land of the tortoises. One of the first men to visit the islands is captain Richard Hawkins in the 15-century or the year 1593. In 1793 James Colnett wanted to use the islands as a type of base called a whaler in the Pacific Ocean.
The Amazon Rainforest
The Amazon Rainforest is also know as Amazonia or as the Amazon jungle it’s a moist forest that covers most parts of the Amazon Basin and the South America. The Basin encompasses has about seven million square kilometers and (1.7 billion acres) and which five and a half million square kilometers are covered by the rainforest. The territory belongs to nine nations.
60% of the rainforest was followed by peru with 13%.States and departmemts of four nations has named the Amazonas after them.
The Amazon represents half of the planet’s remaining rain forest and it’s the largest and most species rich tract of tropical rainforest. As of February 2009 the Amazon was ranking first in Group E, the category for forests, were national parks, and nature reserves. The rainforests contains several species that can pose a hazard. In the river, electric eels can produce electric shock that can stun or kill. Wild peranha’s are known to bite and injure humans. The Amazon rainforest has poison dart frogs that secrete lipophilic alkaloid toxins through there flesh. Malaria, yellow fever and Degue fever can also be contracted in the Amazon region. The main sources of deforestation in the Amazon are human settlement and development of the land. Between 1991 and 2000 the total area of forest lost in the Amazon rose from 415,000 to 587,000 km2 with most of the lost forest becoming pasture for cattle.
LGUAZU FALLS
Lguaz falls is a river but it combines into a waterfall. This is one of the new 7 wonders of the world nature because of the new 7 wonders of the world foundation. This is the group of the fifth for the lake, river and waterfall .The European to find this falls was the Spanish.
The waterfall system is 275 falls along with 2.7 kilometers 1.67 miles of the Lguazu River. The fall can be reached from two towns. You have better views and walk ways. On July24, 2006 a big drought happened in south America  |
it reduced a lot of water to come over on the land and flowing over the fall.
They said that this waterfall looked alike to Victoria falls they said sometimes there can be a lot of floods extreme ones. Victoria splits her pants to five islands. In one of the pictures they have people standing on a bridge looking at the waterfall. This waterfall has a lot of waterfalls from each side and there are little islands in the middle of the waterfall. The walls are very steep and there are bushes and vines and trees around the waterfall and in the middle.
Victoria Falls
At the time: November 17 1855, David Livingstone was the first person to view Victoria Falls. In Zambia, Victoria Falls is called Mosi-oa-Tunya. They also call it “The Smoke that Thunders”. The reason why the waterfall is called Victoria Falls is because, at the time, their Queen was Queen Victoria. So David decided to call the waterfall: Victoria Falls.
Victoria Falls is the largest waterfall in the world. The width of Victoria Falls is 1,728 meters. The height of Victoria Falls is 108 meters. The highest recorded flow rate  |
was 12,800 meters. Victoria Falls was split into five islands.
Victoria Falls has its own national park. Mosi-oa-Tunya also has it very own national park. Victoria Falls National Park is 23 square kilometers. Mosi-oa-Tunya National Park is 66 square kilometers. Victoria Falls has 39 different species of fish below the waterfall. 89 different species above the waterfall.
In the national parks, elephants, buffalos, giraffes, and zebras are mostly seen. Lions and leopards are occasionally seen in the (national) park. Baboons and vervet monkeys are commonly seen at the national park. Hippopotamus and crocodiles have large populations in the above the waterfall. Victoria Falls is a shelter home to many different animals.
Great Barrier reef
The Great Barrier Reef is located in the Coral Sea. It is 1,600 miles long and covers 133,000 square miles. The Great Barrier Reef is the largest reef system in the world and can be seen from space. The Great Barrier Reef is the largest structure made by living organisms they are called coral polyps. A great part of the reef is protected by The Great Barrier Reef Marine Park it helps to limit fishing and tourism.
There are thirty recorded species of whales, dolphins, and porpoises in the Great Barrier Reef as well as 6 species of sea turtles. There are about 125 types of sharks, stingrays, and skates live there. Along with lots more sea creatures there are 215 species of birds 22 of them are seabirds and 32 are shorebirds. The Great Barrier Reef is also home to 2195 plant types the plants are spread by birds.
The biggest threat to the reef is change in temperature because of change in the temperature there has been large coral bleaching. The coral bleaching probably become annual. The climate change also affects some fish that live there, the fish prefer a certain climate so they are leaving so the birds that eat them have no food.
