and Steel structure? And for what purposes is it better to use concrete or steel structures? Concrete is the second most used material for construction after water in the world. Concrete is widely used in today construction industry because of its durability and compatibility. It can be mounded in any shape which makes it a very useful. In addition to the unique aesthetics achieved with concrete construction. Steel has the highest strength-to-weight ratio of any construction material. steel used

one form. Carbon is one of the elements that contain many allotropes. Each allotrope of carbon has its own different properties. The allotropes of carbon are diamond‚ graphite‚ fullerenes‚ carbon nanotubes‚ carbon nanobuds‚ amorphous carbon‚ glassy carbon‚ lonsdaleite‚ and carbon nanofoam. Diamond is the best know allotrope of carbon. It is the hardest known natural mineral which makes it very rough. In the structure of the diamond‚ each carbon atom is covalently bonded to four other carbon atoms and

The carbon cycle shows how carbon is recycled -Carbon dioxide is taken in by plants in order to carry out photosynthesis and make food. -The carbon from the carbon dioxide is used to make carbohydrates‚ fats and proteins that make up the plant body. For example the cell wall of plants is made from cellulose - a carbohydrate. -Some of this carbon is returned into the atmosphere as carbon dioxide when the plant respires. When these plants are eaten by other animals this carbon becomes part

The Carbon Cycle Poppy Matless Carbon is present in all living organisms. When organisms die‚ the carbon is recycled for future generations. 1. Carbon is released as CO2 via respiration and combustion 2. CO2 is absorbed by producers (grass‚ plants etc) 3. Animals feed off of the plant‚ passing on carbon throughout the food chain‚ losing some carbon as CO2 respiration. 4. When the animal dies‚ it is eaten by decomposers‚ and the carbon returns to the atmosphere 5. If decomposition

Carbon is the fourth most abundant element found on Earth‚ and is essential to all life as we know it. It is found in all living substances‚ and is essentially the key element for life. Because the carbon atom has the ability to form bonds with up to four other atoms‚ it can help form solid minerals (such “ limestone)‚ ‘squishy’ organisms (such as plants and animals)‚ and it can be dissolved in water. Carbon is also present in rocks‚ dissolved in rivers‚ lakes and oceans‚ and is in the atmosphere
