Requirements for Agriculture

* Plants can remove metals from low grade ores. The metal can be recovered by processing the ash from burning the plants.

It is a long process to extract Iron to get it from an ore to its final product. In the beginning stages, an iron ore is heated along with limestone and pure carbon in a furnace that reaches temperatures ranging up to 1,500°C (2,700°F); this process helps remove oxygen from iron ore. The limestone is used to erase imperfectirons.

The first reason of why agriculture is a better way of life, is because according to document 1 farmers were less violent. Hunters and gatherers on the other hand were in constant state of tribal warfare. This resulted in 25-30% of adult males dying from homicide. Warfare was necessary to keep population density low. This was due to the fact that a certain place only had so much food to support one person. Farmers on the other hand could use a small piece of land and plant crops that could support many people. They do not have to fight over food therefore less war and violence.

8. To some observers, the mineral shown in Figure 1.6 (p. 5 lab book) exhibits a metallic luster, while others describe its luster as nonmetallic. Based on the streak of this sample, how would you describe its luster? Luster: nonmetallic

The process of transferring the cost of metal ores and other minerals removed from the earth to an

In the late 19th century, many factors affected agriculture in the United States as small farms transitioned to large farms. Technology, government policy, and economic conditions greatly influenced the way agriculture functioned in America. Farmers were exposed to advanced agricultural machinery and suffered from poor economic conditions due to a lack of government intervention. As production of crops increased thanks to the advancements in agriculture and processing, the prices of food dropped, leading to the eventual downfall of American farmers. In addition, the government was rooting for the success of the national economy, even if that meant choosing to neglect the struggling farmers and workers that made that success possible.

In the time period between 1865 and 1900 technology,government policy,and economic conditions really changed American agriculture. The technology made farming more efficient,and more profitable. Government policies both helped and hindered farmers with helping them transport their products,but they also “stole” from the farmers to help make the government more money. The economic conditions helped farmers with selling more products,and helping cities grow;along with starving families almost to death. All of these coming together really changed American agriculture.

1. Decide if the mineral is metallic or non-metallic based on its luster and streak.

Open pit mining is used when a resource is spread out in a rock formation. An enormous hole is dug, and the source is then removed. Open Pit mining is generally used for mining for gold, diamonds, coal, copper and other resources. This method consumes a large amount of habitat that becomes lost. Once mining is completed the pit will generally fill up with water.

Some rock’s in the Earth’s interior that are solid, are so hot that, if the pressure on these were released, or they are convected into a lower pressure zone, they could begin to melt

A mineral is homogenous, naturally occurring substance formed through geological processes that has a characteristic chemical composition, a highly ordered atomic structure and specific physical properties.

Iron can be used for a wide range of resources in the contemporary world. It is the most abundant, least expensive, and most used of all metals. It is vital to human and animal life, and humans use it in a variety of devices to make life convenient. It is combined with other elements to make steel or other compounds for many commercial uses, the most common of which include making fuels, lubricants, automobiles, machine tools, hulls of large ships, building parts, machine parts, cooking pots and pans, cutlery, surgical equipment, and aircraft. Iron (III) “is used in the treatment of sewage, as a dye for cloth, as a coloring agent for paint, an additive in animal feed, and in the manufacture of printed

Coal, a mineral I have discussed previously, is necessary to our everyday lives. Coal is an incredible source of energy; it heats our houses and buildings, and also fuels stoves. You may often wonder where this extremely useful mineral comes from. Coal does not just appear; it needs to be mined through a process which results in our being able to utilize it. Coal mining is fairly inexpensive, is carried out on a large scale and can be mined in either underground or surface mines.

I think agriculture can help schools. Through Agriculture in Schools, students ages 10-14 and their teachers receive training in best practices, including compost-making, proper sowing and cultivation. Students who participate learn to appreciate the great importance and dignity of agricultural work. Agriculture will help with fresh ingredients; young people often have a poor opinion of agricultural work. Clearly, this could be the answer to teach students, how to be able to grow more food of better nutritional quality. Agriculture should be an elective or even a requirement at schools.
