Copper and molybdenum resources were not recognized as valuable commod
Copper and molybdenum resources were not recognized as valuable commodities until economic needs demanded the collection and processing of these minerals in large amounts. The most expansive deposits of copper and molybdenum occur in massive low grade ores and are found in intrusive porphyry formations, although many smaller sized but higher grade ores are located in non-porphyry areas. The nation has abundant domestic copper ore reserves but because of many detrimental economic factors much of

Fertilizer
Fertilizer
Fertilizer A fertilizer is any natural or manufactured material that is added to soil to increase plant growth. Plants cannot live without the primary nutritional elements, nitrogen, phosphorus, and potassium; the secondary elements, calcium, magnesium, and sulfur; and small amounts of boron, chlorine, cobalt, copper, iron, manganese, molybdenum, and zinc--called micronutrients or trace elements. Plants obtain all these elements from the soil. They must be added to soils deficient in them becaus
The Arctic
The Arctic
The Arctic The Artic is a region at the upper most tip of the Northern Hemisphere. The Artic includes the area around Greenland, USSR, Canada and Alaska. Much of the Artic circle is permanently frozen ice. The Artic is a pristine environment, clean and void of human interference. However as humans move into these areas and begin to extract what ever they can be balance can be tipped, resulting in pollution and destruction of the environment. Climate. The Artic winters much longer than the Summer
Differences and Effects of Natural and Synthetic Fertilizers
Differences and Effects of Natural and Synthetic Fertilizers
Differences and Effects of Natural and Synthetic Fertilizers At the core of the growth and germination of plants lie the nutrients they receive from the soil. The nutrients required for growth are classified into two groupings, macronutirents and micronutrients. Macronutrients are those that are needed in very large amounts, and whose absence can do a great harm to the development of the plant life. These nutrients include calcium, nitrogen, phosphorus, and potassium, and are very sparse in most
Diverrsity of Plants
Diverrsity of Plants
Diverrsity of Plants Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago, trees had evolved and formed forests, within which the diversification of vertebrates, insects, and fungi occurred. Roughly 266,000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes and ferns require free water so that sperm can swim

Peru
Peru
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
