Yangtze river Done by: Shuaa AL Nasr 6B
What is the Yangtze river? Where is it located? The Yangtze River (or, "Changjiang" in Chinese, literally, this is the "longest river"), is the longest river in China, running 6,300 kilometers (3915 miles). It is also the third longest river in the world. Its basin, extending for some 2,000 miles from west to east and for more than 600 miles from north to south, drains a huge area in South China. The Yangtze also carries more water than any other river in China. http://depts.washington.edu/chinaciv/geo/yangtze.htm
These black and white bears can be as large as 250 pounds. According to the World Wildlife Fund (WWF), the giant panda is an endangered species that lives in rugged, mountainous areas of China, including along the Yangtze River. Giant pandas exist almost entirely on bamboo, despite the fact that they still have a digestive system more suited to carnivores. Chinese giant salamanders are found in several places in China, including in and around the Yangtze River. They live both in the water and in muddy cracks and under rocks along the river banks. The largest salamander in the world, this amphibian can grow to nearly 6 feet in length. It eats worms, smaller salamanders, snails and Cray fish. Growing to just 13 inches long, the Chinese grouse is the smallest grouse in the world. These birds live in the birch and coniferous forests in and around the Yangtze River at altitudes above 3,000 feet. This bird has black barring on its back, belly and tail, with a brown base color. Its chest is a reddish-brown, and its black throat is bordered by white. This beautiful tree has pure white flowers called dove flowers that resemble doves perched in the branches. This tree is very rare and exists only in a few areas near the Yangtze River and the Shennong Stream, a tributary of the Yangtze. Since doves are a symbol of peace, the Chinese government presents this tree as a gift to representatives of other countries as a symbol of friendship. This large flower is a variety of chrysanthemum that grows wild in dry, rocky pockets along the Yangtze River. It comes in many different colors, especially pale yellow, orange, and gold. Larger than many other chrysanthemums, these plants can grow to 5 feet tall, with blossoms that can be as much as 7 inches across. Some think this flower is called "mother" because of its size, and others say it is because of where it grows, as the Yangtze is sometimes called the Mother of China. China is also one of the countries with the most abundant plant life in the world. There are more than 32,000 species of higher plants, and almost all the major plants that grow in the northern hemisphere's frigid, temperate and tropical zones are represented in China. In addition, there are more than 7,000 species of woody plants, including 2,800-odd tree species. The metasequoia, Chinese cypress, Cathay silver fir, China fir, golden larch, Taiwan fir, Fujian cypress, dove-tree, eucommia and camplothecaacuminata are found only in China. The metasequoia, a tall species of arbor, is considered to be one of the oldest and rarest plants in the world.
A biotic factors The abiotic factors in the river includes acidity, turbidity (clarity), nitrogen nutrient concentrations plus dissolved oxygen concentration. Temperature and sunlight, but also it includes oxygen concentrations, PH levels, discharge, sediment amount and water.
These are some of the natural resources that we can find in rivers. Therefore, we should: • Preserve and protect the natural values of these rivers. • Enhance their water quality. • Fulfill vital conservation purposes by wise use of resources within their surrounding environment. http://dnr.maryland.gov/land/stewardship/scenicrivers.asp
How has science helped me? Science has helped me to discover the use of this natural resources through the following: My teacher has informed me about it. 2) I have observed in my own thinking. 3) I have seen it before. 4) I have researched and asked people around me about its use. 5) I read it in magazines, books, newspapers e.t.c. 6) I have seen it on television, advertisements and movies.
The human activities that affects my biome are: • Picnics • Over fishing/illegal fishing • Oil spills • Improper waste disposal • water pollution • Water poisoning • Killing plants and animals inside the biome.
Natural resources deals with the develop more improved methods of managing those resources to ensure their availability to the future. One way of how it will affect us is to make people’s life better, and another way is to earn money, happy jobs by using the natural resources that are available. Another thing is that it will affect people in the way they live and there shelter, clothing, food and other basic needs. More on next slide…
We are totally dependent on natural resources. Everything we have or use is made of natural resources, or raw materials and energy obtained from the environment. The clothes you're wearing, the chair you're sitting on, your house and TV and school and books, the school bus, city streets, whatever you ate for breakfast, and the package your breakfast came in are made of natural resources. Natural resources sustain human life. More… http://www.media-awareness.ca/english/resources/educational/handouts/ethics/wasting_away.cfm
