In 2005 it was estimated that 48.6% of the world's population lived in urban areas (Encyclopedia of Earth, 2009) with this number constantly on the rise. Urban water provision usually depends on inefficient infrastructure which is susceptible to leakage. People living in cities depend more on large scale farming and food processing industries that require large amounts of water and energy. Urban sprawl contributes to increased flooding and contamination of freshwater supplies because of impermeable surfaces which can negatively affect groundwater levels by decreasing the possibility of water seeping into the ground, increase evaporation of rainwater off bare ground and by polluting groundwater with urban waste (Pennington & Cech, 2010).
"Physical science stands as one of the great achievements of the human spirit."
-Arthur David Ritchie
From the sighting of the Higgs boson to the development of clean energy, physical science research consistently alters the way we see the universe, and brings us life-changing technologies. If you're a science person who wants to learn about the universe and its properties-skimming over details like the organisms that live on earth-then a university degree in one of the physical sciences could be a great choice for you.
Strong written communication skills are important for any student of science, so be prepared to roll up the sleeves of your lab coat, and write some reports and essays. If you need a push in the right direction, browse Marked by Teachers' collection of physical science essays. The teacher annotations will show you what should be included in a good piece of science writing, and before long, you'll be writing and editing your own work with confidence.
Students of the physical sciences often take a higher degree in their field, or in a related subject like one of the biological sciences.Careers paths include business, education and research within academia and industry.
Good conclusions usually refer back to the question or title and address it directly - for example by using key words from the title.
How well do you think these conclusions address the title or question? Answering these questions should help you find out.
Do they use key words from the title or question?
Do they answer the question directly?
Can you work out the question or title just by reading the conclusion?
"In conclusion, it would be impossible to say that there are clear-cut answers to this question as there are both advantages and disadvantages of genetically modifying crops in developing countries. For example, although GM crops could be easier to grow in the infertile soils of Africa and Asia, thus providing more food, there is no guarantee that these crops won't cause serious damage to people's health and to the environment. Scientists cannot yet say whether or not GM crops are safe, simply because they don't know. It therefore seems clear that if people's health is at risk, that should be the most important factor, showing that GM crops are more of a disadvantage than an advantage. However, if it can be proven that Genetically modifying crops is safe to people and to the environment, this opinion would probably be reversed.
"In conclusion human geography focuses on all that is human and physical geography concentrates on the physical processes of the environment. Both elements are interrelated and the focus of their study has changed over time, both areas of geography have made an effort to move away from out dated simplistic theories and both areas have an interest in current affairs. It can be said that although both areas come under the heading of "geography" recently the two disciplines have moved away from each other and have established their knowledge in separate fields of expertise, this can be seen by the fact that human geography articles are published in journals of social science and physical geography articles are published in natural science journals. Space is the key to both sides of geography as both areas are concerned with how communities or environments and their distribution change dependant on their location. Despite the fact that there are many linkages between the two sides of geography, the fact that they are diverging suggests that there are rarely similarities within the two disciplines. That is not to say that this was always the case as geography began as one subject which was concerned with the mapping and cataloguing of regions in order to describe parts of the earth."
"In conclusion, slope movement and magnitude of this movement can be measured and determined in many different ways. Techniques involving technology are the most astute in comparing and contrasting slope movement and the magnitude of this movement. However, the physical measuring of the slope movement highlights and determines ultimately the statue of the slope movement."
