ox bow lakes are better described as diagrams, its hard to explain,

meanders look back on themselves forming a curve
lateral erosion(dont see why it cant be called 'erosion') cuts through the narrow meander neck.
the river straightens it course
the old meander is now isolated on the flood plain.

an onomatpia, *sorry about the spelling* i think....is a word that sound like the word? for example, clatter of cans and cups? to evoke the sound of the hard material? im not sure though...i get them mixed up sometimes. :)
 
:sl:

Yeah, that's right. :) Onomatopoeia is like a splash or a bang, which sounds like the sound associated with the object or action it's referrin to. :)

How to Revise in Business Studies​
​
Revision List​

​
​


Make sure you have a full revision list from your teacher. You must have a checklist of all the topics you must cover. Each topic must also be broken down into sub-topics. Put them in to a table so that you can tick them off as you complete them.


​

​
Revision Plan​
​
Make sure that you have planned when you will revise each topic. Try to stick to this plan as best you can. The important thing is to give yourself enough time to cover all topics before you sit the examination.​
​
Topic Read Through​
​
Read through your class notes on the topic in question. Get a feel for what the topic is about and get yourself familiar with the specialist terminology used.​
​
Condensed Summary Notes​
​
You now need to reorganise your notes in to a more manageable revision form. You can do this on post card sized paper, or even blank post cards themselves.​
​
​
​
This will give you a series of prompt cards for each topic studied. There is no point completely re-writing all your notes – remember that a little knowledge will go a long way if you have good exam technique.​
​
​


Formulae, calculations and definitions​
​



​




​
Revision is not about trying to commit things to memory. You cannot possibly memorise everything in your exercise books, and you should not attempt to. Revision is about understanding. However there are some elements of the subject that you really do need to have firmly in your mind before you go into the examination.


These are largely to do with the Finance and Accounts topic. You must know how to define and calculate:​

​
Costs and Revenues


Gross and Net Profits (or Losses)​

Gross and Net Profit to Sales Ratios​

Break Even output/sales levels​

Contribution​

Assets and Liabilities (Current and Fixed/Long Term)​

Working Capital​

Current Ratio​

Acid Test Ratio​

Return on Capital Employed​

Net Cash Flow and Closing Bank Balances​


​
Write out a sheet with all the necessary formulae and definitions of each of these. It is very important that you know each of these and how to calculate them – they are easy marks to get if you can do it.


​
Examination Skills and Technique​
​



​




​
​
Your final mark is going to be based not only on what you know but how well you are able to use that knowledge in the examination situation. To do this you must remember that every time you look at a question you must be able to SCAM:


​

​
​
S​
UBJECT MATTER: know what the subject matter of the question is


​





​
C​
OMMAND WORD: how does the examiner want you to answer the question? Is it a straightforward ‘State’ or ‘Outline’ , or does it require a more demanding approach, such as ‘Discuss’, ‘Explain’ , ‘Evaluate’ , ‘Describe’ or ‘Examine’ ?


​





​
A​
ND………………..


​





​
M​
ARK ALLOCATION: make sure you write with the mark allocation firmly in mind. have you got enough detail and explanation into your answer for the mark allocation?


​




​
The only way to develop these skills is to keep on practising past questions. These are always available form your teacher.​

What is the catalyst used for the purification of haematite in the blast furnace and what waste products does it produce and how are these removed?
 
aslaam alykum,

limestone is used to purify, in the heat of the furnace the calcium carbonate breaks down to form carbon dioxide and calcium oxide, the calcium oxide reacts with the acidic impurities to form slag, it is ligher than molten iron so floats and can be tapped of.

ok when slag cools, what are its uses? list three.

apply into concrete and cement
used for road making
used in making mineral wool

:D Mineral Wool: http://www.eurima.org/mineral_wool/composition.html

what_m_w.gif
Mineral wool has a unique range of properties combining high thermal resistance with long-term stability. It is made from molten glass, stone or slag that is spun into a fibre-like structure which creates a combination of properties that no other insulation material can match.







Namely the ability to:


  • Save energy
  • Minimise pollution
  • Combat noise
  • Reduce the risk of fire
  • Protect life & property in the event of fire
The properties derive from its structure, a mat of fibres which prevent the movement of air and from its chemical composition. All mineral wool products exhibit exceptional thermal, fire and acoustic properties. Inorganic rock or slag are the main components (typically 98%) of stone wool. The remaining 2% organic content is generally a thermosetting resin binder (an adhesive) and a little oil. Glass wool products usually contain 95% to 96% inorganic material.

Stone wool is made from volcanic rock, typically basalt or dolomite, an increasing proportion of which is recycled material in the form of briquettes. Slag wool is made from blast furnace slag (waste).

The briquette can be from recycled material
​
Glass wool is made from sand or recycled glass, limestone and soda ash; the same ingredients as for familiar glass objects such as window panes or glass bottles. In addition, glass fibre has boron added to improve its moisture tolerance.

CE Marking

The Construction Products Directive (89/106/EEC) requires products to be 'CE' marked which shows their conformity with EU standards. The CPD aims to harmonise the tests, performance declarations and conformity testing across Member States in order to remove any barriers to trade through having to comply with differing national standards.

A CE marked product can be sold anywhere in the European Economic Area. It should be noted that it is not a label of quality with, for example factors such as reliability or durability not taken into account.

Uses:

The using mineral wool section of this site focuses on Health Aspects to provide Practical Tips on using mineral wool and offer a series of case studies.
