Select either a MINERAL or a ROCK that has some economic value, practical use, or a harmful or beneficial effect. Create a discussion thread with the name of the mineral/rock as the title of the thread In your post, compose a paragraph or two and include the following:
The name of the rock or mineral.
A description of its chemical/mineralogical composition.
The geological conditions under which it forms.
Where it is found, and how it is collected.
A discussion of its economic value, practical use, harmful or beneficial effects.
Feel free to include an image of your rock/mineral (not required).
Include the NAMES and SOURCES of the materials you used to find the information you used in your post.
A MINERAL or a ROCK that has some economic value
Limestone
Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaC03. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water. Most of them are found in shallow parts of the ocean between 30 degrees north latitude and 30 degrees south latitude. Limestone is extracted from the rock either by blasting or mechanical excavation depending on the hardness of the rock. Limestone has numerous uses: as a building material, an essential component of concrete (Portland cement), and as white pigment or filler in products such as toothpaste or paints.
At the outset, language is an evident barrier to good communication. Ordering new materials supplies in a foreign language may be done with no trouble with the help of a translator, but to make clear complex technical methods or setting up marketing plans and recruitment will oblige a considerable amount of understanding of traditions and laws that may be relevant. Secondly local laws may be significantly different of those from the original base. Labour laws may vary, trade unions may be tougher resulting in more company disputes; environmental issues may mean an increase in production cost to manufacture in a more environmentally friendly manner furthermore the most common downfall are import restrictions for example businesses operating in the EU, but from non-EU countries, are needed to source more than 70 per cent of their production inputs from within the EU. Thirdly input factors can have varying quality. Labour is a good example, basic numeracy and literacy skills varying across developed and less developed countries. These skills are crucial for training staff particularly those who require using a computer controlled machinery. Enhancing skills within the work force will be beneficial but organisations aim to cut time by taking the international company’s highly productive workers. Lastly well known global companies such as Nike have been heavily criticised for the exploitation of their workers this has a very big effect on their brand image and negative press means that they may lose out on potential shareholders.
After evaluating both sides for and against globalisation, globalisation has brought the world together and with time and with all the advance in technology I feel that nations will begin to interact more effectively and efficiently. International trading means that more consumers needs are met and the broaden of independence ideals to developed nations. Globalisation can be beneficial to many countries around the world because regional economic mixing means that there are concurrence between countries in a geographic
