Plants and Life on Earth Essay

Plants are the only organisms that can convert light energy from the sun into food. And plants produce all  of the food that animals, including people, eat. Even meat. The animals that give us meat, such as chickens and cows, eat grass, oats, corn, or some other plants. Plants make oxygen One of the materials that plants produce as they make food is oxygen gas. This oxygen gas, which is an important part of the air, is the gas that plants and animals must have in order to stay alive. When people breathe, it is the oxygen that we take out of the air to keep our cells and bodies alive. All of the oxygen available for living organisms comes from plants. Plants provide habitats for animals Plants are the primary habitat for thousands of other organisms. Animals live in, on, or under plants. Plants provide shelter and safety for animals. Plants also provide a place for animals to find other food. As a habitat, plants alter the climate. On a small scale, plants provide shade, help moderate the temperature, and protect animals from the wind. On a larger scale, such as in tropical rainforests, plants actually change the rainfall patterns over large areas of the earth’s surface. Plants help make and preserve soil In the forest and the prairie, the roots of plants help hold the soil together. This reduces erosion and helps conserve the soil. Plants also help make soil. Soil is made up of lots of particles of rocks which are broken down into very small pieces. When plants die, their decomposed remains are added to the soil. This helps to make the soil rich with nutrients. Plants provide useful products for people Many plants are important sources of products that people use, including food, fibers (for cloth), and medicines. Plants also help provide some of our energy needs. In some parts of the world, wood is the primary fuel used by people to cook their meals and heat their homes. Many of the other types of fuel we use today, such as coal, natural gas, and gasoline, were made from plants that lived millions of years ago. Plants beautify Plants, because of their beauty, are important elements of out human world. When we build houses and other buildings, we never think the job is done until we have planted trees, shrubs, and flowers to make what we have built much nicer.

Ocean, Meteorology and Atmosphere - Assignment Example The movement of sand on a beach environment is a complex process controlled by natural processes such as winds and storms as well as human-induced factors such as destruction of dune vegetation as well as construction structures such as jetties, groins, and seawalls among others. 13. Distinguish between a flood current and an ebb current. Of flood current, ebb current, high slack water, and low slack water, when is the best time to navigate a boat in a shallow, rocky harbor? A flood current is the tidal current moving from the sea to the shore while ebb current is the tidal current receding seawards. It is best to navigate a boat in a shallow, rocky harbor during low slack tides. 14. Are estuaries associated with submerged or emergent coasts? Yes, Estuaries are associated emergent or submergent coasts with the ones along submergent coastlines being larger while the ones along emergent coasts are smaller. 4. How does the Coriolis effect modify air movement? The Coriolis effect normally modifies air movement by deflecting the air to the right of its motion in the Northen hemisphere and to the left of its motion path in the Southern hemisphere. 9.Describe the principle of the aneroid barometer. An android (no liquid) barometer is made of evacuated metal chambers that work by compressing with the increase in air pressure.

The Rock Cycle Essay Example | Topics and Well Written Essays - 250 words

The Rock Cycle - Essay Example The rock cycle is a way of representing the relationship among the three main types of rocks namely sedimentary, igneous and metamorphic rocks. The rocks undergo a constant gradual transition from one form to another. The transitions depend on the physical conditions around them. This paper discusses the cycle and the way in which the rocks change from one form to the other.  The rock cycle is a way of representing the relationship among the three main types of rocks namely sedimentary, igneous and metamorphic rocks. The rocks undergo a constant gradual transition from one form to another. The transitions depend on the physical conditions around them. This paper discusses the cycle and the way in which the rocks change from one form to the other.  Under the earth surface, the conditions available do not allow the rocks to exist in their solid state. Instead, they exist as magma that is a hot liquid. As the magma moves upwards, cooling takes place, and it finally solidifies to for m the igneous rocks. Some of the magma under pressure during the process of volcanicity moves out as lava on the earth surface. The result is volcanic rocks, which are of fine grains (Mattern, 2005).   On the earth surface, igneous rocks undergo the process of weathering since their components do not stabilize at the surface conditions. Moving water and wind are the main factors of weathering. The rocks are broken down to pieces or sediments and carried away mixing up with other components. After quite a long duration of time, the sediments are finally glued together to form sedimentary rocks (Mattern, 2005). Exposing the rocks to high temperature and pressure on the earth surface causes a physical change on them. The high temperature cause hardening of large masses of rocks called metamorphic rocks. The metamorphic rocks are responsible for forming Mountains. Both the metamorphic and sedimentary rocks can melt again to form magma under high temperature. Weathering occurs again on metamorphic rocks, resulting to the formation of sedimentary rocks. The rock cycle starts over continuously (Mattern, 2005).

The advances of military logisitics since WWI Research Paper

The advances of military logisitics since WWI - Research Paper Example Because of its central contributions to combat, military logistics has received a significant amount of critical attention. Indeed, the 20th century witnessed tremendous innovation and development in military logistics. This research considers American military logistic advances since World War I. World War I witnessed considerable advances in American military logistics. One of the greatest considerations within World War I logistics was that the sheer enormity of the war resulted in past logistic processes being outstripped. This war witnessed amounts of men and machines that the country had never prepared. It’s considered that the average amount of ammunition used was as much as ten times pre-war estimates. Adding to these logistic problems was the consideration that establishing trenches required significant amounts of supplies. As a result, the early stages of the conflict experienced tremendous shortcomings in logistic transport, particularly in the areas of ammunition. Much logistic innovation during World War I then emerged as a response to these infrastructure challenges. A major innovation during this period was the implementation of tanks and gun sleds to lead the military advance, while military supplies would be delivered to railheads and ports many miles away (Lynn 1993, p. 109). In addition to logistic innovations, logistic shortcomings during this period had a corresponding impact on military strategy. The main recognition in these regards was that it no longer was more efficient to supply armies on the move than static armies. This realization had a corresponding impact on the very strategic initiatives within the conflict. Namely, the significant size of military operations necessarily resulted in trench warfare. There were a number of major logistic innovations during World War II that revolutionized military conflict. One of the most seminal innovations was the development of the

English 32 world literature Essay Example | Topics and Well Written Essays - 1250 words

English 32 world literature - Essay Example The diary is in fact a criticism of the traditional authoritarian ways of society. First of all, the narrator repeatedly mentions that parents pass on their tradition to their children and that this tradition is evil. In Part II, he notices that the children are looking at him with a certain kind of hatred. Now, since these children were not there twenty years ago when he committed a mistake with â€Å"Mr. Ku Chiu’s account sheets† (Lu Xun II), he concluded that â€Å"they must have learned this [mistake] from their parents!† (Lu Xun II). That is why they seem to look at him with contempt and hatred. It seems then that the parents of these children must have taught them how to hate and insult others. Through this particular line, the narrator also implies that, in the place where he lives, parents teach the wrong values and practices to their children, like how to insult and criticize other people. He also mentions the same thing in Part VIII when he argues with a twenty-year-old man about the rightness of eating human flesh. Towards the end o f their conversation, he says perhaps with disappointment and fear, â€Å"[The young man] must have been taught by his parents [and] I am afraid he has already taught his son† (Lu Xun VIII). Through this line, he implies once more that the people in his place always pass on the wrong values and practices to their children, such as the idea that cannibalism is right. Finally, he also uses this line to affirm the reason he has stated earlier on why the children look at him: â€Å"That is why even the children [in Part II] look at me so fiercely† (Lu Xun VIII). From this line he implies that perhaps all the children in his village have the same fate as the young man’s son – the fate that they are destined to follow the evil of their parents. Another proof that the diary is about a condemnation

Women's Liberation Movement Essay Example | Topics and Well Written Essays - 2500 words

Women's Liberation Movement - Essay Example The women were forced; especially the American women used all the possible means to liberate themselves during the time. They needed to stand on the political throne, vote and receive votes just as the men and that Collins compared with the 2008 parliament. American women also got tired with the house slavery, as their chore was to rear children and keep houses while men get to work. The women also had the urge to work and earn income just like the men. In addition, economic situation in the 1960s offered them a lot for them in the job market. Life was not easy for women as men censored most of the things they did while no one, not even the legal system was on their side to defend their plights. The women had no option, but to receive a just amicable way of pleading for their rights. However; the government was adamant, Washington never took the time to address their plight thus they were forced to come up with more aggressive moves. At this time, the American women find it hard to l ive without controlling their dressing mode as this was governed and evaluated by the society. The women could not make their independent choices on their leisure activities, as travels, as well as they were not accepted in some modest places due to gender imbalances. They felt closed and enslaved that they opted for liberation measure. As Collins takes the comparison to today’s American woman has made a number of great steps, although all their expectation as equity is concerned have not been achieved. Thesis Statement Though, women are often despised, they have made a lot of progress and constantly struggled to liberate themselves from economic, political and social discrimination. Introduction Women liberation movements have immensely succeeded in many spheres of women life. Collins has produced a book, which significantly describes the effect of gender and societal perception on it. She gives a detailed account after account of women from 1950s to 2008 to draw the distinc tion of the position of a woman in the different societies over the time. She writes this based on researches and data from different times. She uses real people to show the reality of women situation across the times. Collins puts side-by-side comparison of the American woman before and after her fights for liberation. He depicts an enslaved 1950s woman and measures their achievement against those like Hilary Clinton. The books shows that woman liberation, although has been tough, has seen woman freer and more protected by her rights and economically. Social Organizations When women started to realize that they could preform equally like men, they started voicing their grievances, but Washington was so reluctant to help them, thus the women sought alternative measures. Although, the women got some support from some men, most of their queries were addressed by themselves. The period of history that Collins writes about is regarded as the time when life was much less enjoyable to the women, also referred what the women on ‘Mad Men’ know1. The book gives accounts of women from politicians to homemakers, underwent suffering due to their feminine nature. The societal values and cultural system gave the women the lowest state in the society. Collins accounts for the effects of the battles these women fought to achieve acceptability in the society. The book gives early lives of women like Phyllis Schlafly, who worked hard trying to convince her sisters about their

International Business Globalization and Trade, Multinational Research Paper

International Business Globalization and Trade, Multinational Enterprise - Research Paper Example China and India are becoming economic giants and this evident by the way their products are competing perfectively with goods from developed countries like the U.S, UK, and Germany. The two nations have embraced ‘frugal innovation’ system which advocates for producing more for less. The frugal invention helps in cutting production cost of production and this has been an added advantage to Companies operating in the two upcoming economic superpowers. (Urata and Chia et al., 2006). Factors leading to Economic growth in Asian States Innovation is the application of improved solutions which meet the new requirements, inarticulate needs or the existing market needs. This is achieved through more effective products, processes, services, technologies or ideas which are readily available to markets, governments and society. This is happening in Asia where China and India have decided to end developing country life and join the group of developed countries. Frugal innovation has been highly used in China and India. Frugal innovation is the process of reducing the complexity and cost of production of a product. This kind of innovation helps firms in growing at a faster rate by reducing production cost. Frugal innovation has made many firms in Asia to have a competitive advantage (Mason, 2001). Reverse innovation is the kind of innovation used by most of the developing countries. This is a kind of innovation whereby goods developed as inexpensive models to meet the needs of the developing nations. (Govindarajan and Trimble, 2012). Jugaad invention is in full force in both China and India. This is a process of improvising production materials due to lack of enough resources for production. China and India have been using and producing their products using their local readily available resources. These forms of innovations used by the two Asian nations has played a big role in product development (Radjou and Prabhu et al., 2012). China and India incorporated gl obalization in their system. This process has helped the two nations in borrowing technology from developed countries and use them in the production of high-quality affordable products. Frugal innovation in Asia The origin of Frugal Innovation Using the concept of innovation, frugal innovation develops on the theories of movements and capabilities that have been there before. Frugal innovation can be traced back from the appropriate technology movement. This was as a result of a publication by Schumer in 1975 with the topic, ‘Small is beautiful: Economics as if People Mattered’ this was aimed in campaigning the local development of low technology, labour-intensive, environmentally technologies as the substitute to depending on technology- transfer from developed countries. After growing as a global movement, the attractiveness of the intermediate which later became appropriate technology sends a warning message, for it was increasing the implications of second class qua lity. Due to threats like environmental challenges due to ozone layer depletion, the appropriate technology was overtaken by sustainable development which forced countries like China and India to come up with ways of growing their economy (Bound & Thortin 2012). The evolution of frugal innovation was influenced by several factors. The factors included; social movements which helped in the globalization of science technology and innovation. There was the availability of technology for the two countries had tapped it from some developing countries. The growth of the private sector increased networking of the global innovation system as multinational firms explored new locations for R&D.
