The Himalayas along China's southwestern frontier with India are the world's tallest mountains. China's greatest river, the Yangtze, is the world's fourth longest. The Taklimakan Desert, in western Xinjiang Uygur Autonomous Region, is one of the driest spots on Earth. The area of loessic soil (fine, siltlike soil created by wind action in dry regions) in Shaanxi and Shanxi provinces is probably more extensive than in any other place. China has a great wealth of mineral and natural resources. Re

It is located in two continents—Asia and Europe, but mostly Asia. There are a lot of things about Turkey that one could talk about… Let's talk about the size first. In area it is about 300,000 square miles. As mentioned

Transgenic Rice Plants For centuries, rice has been one of the most important staple crops for the world and it now currently feeds more than two billion people, mostly living in developing countries. Rice is the major food source of Japan and China and it enjoys a long history of use in both cultures. In 1994, worldwide rice production peaked at 530 million metric tons. Yet, more than 200 million tons of rice are lost each year to biotic stresses such as disease and insect infestation. This ext

Tungsten
Tungsten In 1779 Peter Woulfe examined the mineral known as Wolframite and concluded it must contain a new substance. Scheel, in 1781, found that a new acid could be made from Tungsten (a name first applied in 1758 to a mineral known as Scheelite). Scheele and Berman suggested the possibility of obtaining a new metal by reducing this acid. The de Eelhuyar brothers found acid in Worlframite in 1783, which was identical to that found in Tungsten (tungstic acid). In that same year they succeeded i

The toilet was first patented in England in 1775, invented by one Thomas Crapper, but the extraordinary automatic device called the flush toilet has been around for a long time. Leonardo Da Vinci in the 1400's designed one that worked, at least on paper, and Queen Elizabeth I reputably had one in her palace in Richmond in 1556, complete with flushing and overflow pipes, a bowl valve and a drain trap.

Platinum Platinum is a relatively rare, chemically inert, metallic element. It symbol is Pt, atomic number is 78, and its atomic weight is 195.09. Platinum is one of the heaviest substances known. One cubic foot of Platinum weighs 21 times as much as a cubic foot of water. A grayish-white metal, Platinum has a melting point of 1772 degrees C and a realatively high boiling point of 3827 degrees C. It has a high fusing point, is ductile and malleable, expands slightly upon heating, and has high el

Nuclear Energy
Nuclear Energy
Nuclear Energy Nuclear energy-This is energy that binds together components of an atomic nucleus. This is made by the process of nuclear fission. Nuclear fission is produced when an atomic atom is split. The way nuclear pore is made is in a nuclear reactor, this is most likely located in a nuclear power plant. the fission that is produced is when a heavy element splits in half or is halved into two smaller nuclei, the power of the fission is located by the rate of the splitting of the nuclei at

Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, oxygen is the most abundant element at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all living organisms. Oxygen is a gaseous chemical element in Group VA of the per

Peru Peru's gross domestic product in the late 1980s was $19.6 billion, or about $920 per capita. Although the economy remains primarily agricultural, the mining and fishing industries have become increasingly important. Peru relies primarily on the export of raw materials—chiefly minerals, farm products, and fish meal—to earn foreign exchange for importing machinery and manufactured goods. During the late 1980s, guerrilla violence, rampant inflation, chronic budget deficits, and drought combine
