Question

how is the raw material of coal produced?

Answer 1

Coal is formed from plant remains that have been compacted, hardened, chemically altered, and metamorphosed by heat and pressure over geologic time.

Coal was formed in swamp ecosystems which persisted in lowland sedimentary basins similar, for instance, to the peat swamps of Borneo today. These swamp environments were formed during slow subsidence of passive continental margins, and most seem to have formed adjacent to estuarine and marine sediments suggesting that they may have been in tidal delta environments. They are often called the "coal forests".

When plants die in these peat swamp environments, their biomass is deposited in anaerobic aquatic environments where low oxygen levels prevent their complete decay by bacteria and oxidation. For masses of undecayed organic matter to be preserved and to form economically valuable coal the environment must remain steady for prolonged periods of time, and the waters feeding these peat swamps must remain essentially free of sediment. This requires minimal erosion in the uplands of the rivers which feed the coal swamps, and efficient trapping of the sediments.

Answer 2

coal doesnt need raw material. It occurs in free form. Being an organic material it doesnt react unless heat is provided. It is just mined out
However, if youre looking for coal free from impurities like dust, destructive distillation of coal is important. For this you take it in a test tube and heat it in absence of air

Answer 3

Most of our coal was formed about 300 million years ago, when much of the earth was covered by steamy swamps. As plants and trees died, their remains sank to the bottom of the swampy areas, accumulating layer upon layer and eventually forming a soggy, dense material called peat.

Over long periods of time, the makeup of the earth's surface changed, and seas and great rivers caused deposits of sand, clay and other mineral matter to accumulate, burying the peat. Sandstone and other sedimentary rocks were formed, and the pressure caused by their weight squeezed water from the peat. Increasingly deeper burial and the heat associated with it gradually changed the material to coal. Scientists estimate that from 3 to 7 feet of compacted plant matter was required to form 1 foot of bituminous coal.

Answer 4

by decomposed wood lying under ground for a very long time and submitted to great pressure and warmth. If it gets hot and squashed enough you get diamond. Not a very scientific answer but you get the idea.

Answer 5

You sound like me when i was 16. ^_^ Jobs for biology: any type of Medical Doctor, but this requires 4 years of undergraduate school, at least six years of post graduate school and then years of internships Clinical Research, which involves working with pharmaceutical companies to develope and test experiment drugs that haven't been approved by the FDA to sell in the market yet. There are all different kinds of stages of clinical research from the initial testing on animals, all the way through to the drug being on the market for people and reevaluating it for further benefits. There is also just any type of scientist, from digging up dinosaur bones as a paleontologist or studying weather patterns as a metiorologist. You have to narrow it down to what type of science you like the best. There are a lot of Ivy League schools that have great biology programs, like Penn U, Princeton and UMDNJ. Find out what colleges your science teachers attended and if they liked the programs. Also, go to college fairs and sign up to receive info in the mail. You'll receive piles and piles of college stuff in the mail, but take a Saturday afternoon and go through all of them. Anything that looks like it would be strong in science, look them up on the internet for more information. To get into a good college, take as many science classes in high school as you can. Most high schools will give students the standard curriculum: 1 math, 1 science, 1 social studies and 1 english/literature. However, when you get to your junior and senior year, you can usually opt out of some classes and take additional science classes instead of something like a foreign language or phyis ed. my 11th grade year I took biology and chemistry and then in 12th grade I took AP biology and physics. You may think, "but i'm not interested in chem or physics." but, in college with a biology major you'll be required to take upper level chem and some physics classes to graduate. Having a strong background in these classes will aid you in getting accepted into college. Also, find out if there are any science fairs you can participate in locally. Even if you don't win, that's still bonus points on your application. And, of course, apply early! Take your SATs junior year and apply before the end of your junior year. Early acceptance is a big plus. Also, apply to at least four schools. hmmm, fun facts, eh? Let's see.... -Look up a guy named Phineas Gage. Interesting story. -your brain is the size of a grapefruit and your heart is the size of your fist. -there are 206 bones in the adult human body, but 300 when we are children. Many of our bones fuse together as we get older -the more bumpy your brain is, the smarter you are. Its all about surface area. -the smallest bone in your body is in your inner ear -the longest cell in your body is your motor neuron that can stretch from your big toe to your lower spinal cord -the most poisonous animal in the world is a frog in south america -the stegosaurus was over 25 feet long, but had a brain smaller than a golfball -the human eye blinks over 4 millions times per year -it takes about 12 hours for food to entirely digest -the longest living cells in the body are neurons, which can last your whole life. However, neuron cells cannot regenerate or replicate, so once they die, there is no going back -there is more computer technology in a Nintendo game system (the ones from the 1980s) than in the Hubble Space Telescope. -the average human brain weighs 3 lbs, but the heaviest ever recorded was over 5lbs -plants "lean" towards a sunny window because the lack of sunlight on the dark side of the plant causes a reaction that makes the cells swell. The plant is not "leaning towards the light" on purpose.
